Lemon Diseases And Treatment - Tips For Treating Lemon Diseases
If you are lucky enough to be able to grow your own lemon tree, chances are good that you have encountered one or more lemon tree problems. Unfortunately, there are a plethora of lemon tree diseases, not to mention pest damage or nutritional deficiencies that can affect how, or if, your lemon tree bears. Knowing how to identify lemon diseases and the treatment for diseases of lemons will allow you to take immediate action to mitigate potential negative impact on fruit.
Below are some of the most common diseases of lemon with tips for treating them.
Citrus canker – A highly contagious bacterial infection, citrus canker causes yellow halo-like lesions on fruit, leaves and twigs of citrus trees. If allowed to progress unchecked, this lemon tree problem will eventually result in dieback, fruit drop, and leaf loss. This disease is spread through the air with the aid of air currents, birds, insects and even humans. Spray with liquid copper fungicide as a preventative for treating citrus canker lemon disease. If the tree is already infected, there is no treatment and the tree will have to be destroyed.
Greasy spot fungus – Greasy spot is a fungal disease of lemons whose symptoms include telltale yellow-brown blister on the underside of the leaves. As the disease progresses, the blisters begin to look oily. Treating this lemon disease also requires an application of liquid copper fungicide. Spray first in June or July and follow up with another application in August or September.
Sooty mold fungus – Sooty mold is a fungal infection resulting in black leaves. This mold is the result of honeydew excreted from aphids, whiteflies and mealybugs. To eradicate sooty mold, you must first control the insect infestation. Spray the lemon tree with Neem oil insecticide, both the top and undersides of the foliage. You may need to repeat in 10-14 days, depending upon the extent of the infestation. Follow up by treating the mold growth with liquid copper fungicide.
Phytophthora fungus – Phytophthora root rot or brown rot or collar rot is caused by the phytophthora fungus resulting in hard dark brown patches on the trunk of the tree often accompanied by oozing from the affected area. As the disease progresses, the patches dry, crack and die leaving a dark, sunken area. Fruit may also be affected with brown and decayed spots. This fungus lives in the soil, especially wet soil, where it is splashed up onto the tree during heavy rain or irrigation. To treat, remove all infected leaves and dropped fruit from the ground. Prune the lower branches from the tree, those that are more than 2 feet (.6 m.) from the ground. Then spray with a fungicide such as Agri-Fos or Captan.
Botrytis fungus – Botrytis rot is yet another fungal infection which may afflict lemon trees. It tends to develop after prolonged rainy periods, usually along the coastline, and moves from old blooms to newly developing blossoms in the spring. For this fungal infection, spray the lemon tree with a fungicide according to the manufacturer’s instructions.
Anthracnose – Anthracnose is also a fungal infection that causes twig dieback, leaf drop and stained fruit. It is caused by Colletotrichum and is also more common after prolonged periods of rain. As with Botrytis, spray the lemon tree with a fungicide.
Other less common diseases which may plague lemon trees are:
- Armillaria root rot
- Dothiorella blight
- Tristeza twig dieback
- Stubborn disease
Consult your extension office or a reputable nursery for information on these diseases and how to combat them.
Most importantly to prevent not only disease but other lemon tree problems, be sure to be consistent with your irrigation and feeding schedules, and monitor for pests and treat accordingly at the first signs of infestation. Also, keep the area around the lemon tree free from debris and weeds that harbor fungal disease as well as insects.

7 Common Lemon Tree Problems & How To Fix Them
Sometimes life hands you lemons. Other times, we actively seek them by growing our own lemon trees.
There really isn’t anything like having a citrus tree in your garden. They look great, making any space look like a summer paradise. Lemon trees are no exception. They’re a favorite to grow, mainly because they’re relatively easy to care for. They also grow well in various climates and conditions. Their main benefit is how quickly they produce fruit.
However, lemon trees have one downside.
They’re prone to a long list of pests, diseases, and problems. If you don’t catch them in time, you could end up with no fruit at all. Some of these problems could be the result of bad gardening habits, others are just pets and diseases that spring up when you least expect it.
Luckily, there are solutions and preventative measures. You’ll be making lemonade in no time.
Care Guide To Lemon Trees
Before we get into the list of lemon tree issues, let’s recap on the best way to care for your lemon tree.
Lemon trees love plenty of light. Plant them in the sunniest spot in your garden so they can bask in the rays for at least six hours a day at minimum. Semi-tropical and tropical climates are the best for lemon trees (USDA zones 8-11).
Lemon trees are the most sensitive of citrus trees when it comes to colder temperatures, thriving in temperatures in the upper 70s and 80s. They also love high levels of humidity.
Like most citrus trees, lemons need well-draining, textured soil with slightly acidic levels. Avoid mulching around the base of your lemon tree and make sure there is no pooling water when you do water.
Speaking of watering your tree, make sure you maintain moist soil throughout the warmest days of summer. Younger trees need frequent watering, sometimes as often as twice a week. Older lemon trees do become more drought-tolerant, but don’t skip out on watering altogether.
Younger lemon trees may need more regular pruning to encourage healthy branch growth. Pruning also allows for air to flow easily between branches and leaves, and allows more light to reach all areas of the tree.
Now that we’ve got the care guide down, let’s get into the seven problems of lemon trees, and how to tackle them.
1. Lesions On Leaves – Citrus Canker
One of the most devastating common lemon tree diseases is citrus canker. This disease is caused by the bacterium Xanthomonas citri. Going back to the 1900s, it was first discovered in Texas and Florida. Many believe that it originated in Japan, finding its way to the states on shipped lemon tree seeds.
Citrus canker first appears on your lemon tree leaves. Small lesions pop up on both sides of the leaves. They’re often raised and look like small craters. These cankers or spots look like water stains and have a yellow ring around them. If left unattended they will spread to the stems and fruits.
Citrus canker infections aren’t harmful to humans, but they will devastate your lemon tree and other members of the citrus family. Defoliation, fruit drop, and shoot dieback are common symptoms of citrus canker that’s been left to spread.
What’s worse is that this disease spreads easily by cross-contamination of plant tools, wind, and rain. The movement of infected plants and even birds can also spread citrus canker. The citrus canker bacteria survive for 10 months on leaves, plant debris, and the bark of infected trees, making this disease difficult to control.
Prevention is the only ‘cure’ when it comes to citrus canker.
When the disease first appeared and destroyed agricultural citrus trees, the solution was to burn all infected trees. Other trees within a 50-foot radius were burnt too. Today though, preventative measures are the go-to way when dealing with citrus canker.
Preventative copper bactericides are often used, together with good garden maintenance. You could even opt to grow resistant varieties. But, if you notice a citrus canker infection, your only option is to, unfortunately, destroy your lemon tree.
2. Black Moldy Spots – Sooty Mold (And Aphids)
Sooty mold is a common disease for many plants, especially those loved by aphids. Lemon trees are no exception. Sooty mold grows on the sticky substance secreted by aphids, known as honeydew.
This mold is black and while technically not harmful to the plants, it prevents photosynthesis, having devastating consequences. And, a huge aphid infestation leads to defoliation and the death of your lemon tree.
You’ll quickly know if you have an aphid and sooty mold problem. Your lemon tree leaves and branches will look like they’ve been dusted in ash and covered in black grime.
One of the best ways to prevent sooty mold from taking over your lemon tree is to get rid of aphids. They’re an easy pest to evacuate from your garden. You can simply pick them off your lemon tree leaves and throw them in a bucket of soapy water.
Another go-to hack is to spray them off your leaves with a trusty water spray bottle. Alcohol sprays and horticultural oils can be thrown in the spray bottle as an added aphid-killing measure. You can also use them to wipe the aphids off the infected leaves.
Introducing natural aphid predators is another great way to get rid of aphids and with them, prevent sooty mold. Ladybugs are great little aphid eaters that won’t harm any of your plants or other helpful insects. You’ll want to check out how to purchase and release lady bugs if you choose that route.
Once you’ve got your aphid infestation under control, you can simply wash off all that black sooty mold. Use horticultural oils to wipe off mold stubbornly sticking to leaves and branches.
3. Fuzzy Gray Mold And Brown Spots – Botrytis Blight
Seasoned gardeners are probably no strangers to botrytis blight.
Botrytis cinerea, the fungus causing this disease, grows best in high humidity and most often occurs after long periods of rain. It lives on infected plant debris and easily spreads by wind and rain. Once it lands on your lemon tree, all it needs is a little bit of moisture to germinate.
This fungus quickly attacks lemon tree leaves, small branches, flowers, and even the lemons, leaving behind a brown or gray fuzzy mold and dark brown spots. Flowers eventually drop and fruit won’t set. This gray mold ends up covering fruit that has already set and causes the branches to die back.
Botrytis blight can easily be prevented. Lemon trees planted in the sunniest spot in the garden and spaced out correctly eliminate some conditions that botrytis blight thrives in. Your lemon tree dries faster in the sun and with good air circulation.
You should always practice good garden hygiene, especially if you’re wanting to prevent diseases like botrytis blight. Throw away dead foliage and plant debris to avoid attracting disease. Be careful during wet weather though, as you could accidentally spread the disease when handling infected debris.
If you spot botrytis blight growing on your lemon tree leaves, prune them away immediately. Make sure you clean your pruning shears when you’re finished.
4. Tan Spots with Dark Outlines – Anthracnose
Another fungal disease to look out for is anthracnose. Like botrytis blight, it affects leaves, shoots, twigs, and stains lemons.
Anthracnose is easy to spot. Like most fungal diseases, it first appears as odd-colored lesions on affected areas, like leaves and branches. These spots are tanned with a noticeable dark outline, looking like a healing bruise. Eventually, the middles of these lesions turn dark, and often small black specks appear when the fungus spreads.
Anthracnose on lemon fruits looks slightly different. The spots are often sunken and sickly brown. When it spreads across the fruit, the center of these spores turns pink and the fruit begins to rot. Small twigs and baby shoots are also affected, causing dieback and defoliation.
Anthracnose thrives in cold, wet, and humid conditions. It spreads quickly and easily, especially during the wettest times of the year. Water splashing off infected plant debris helps this disease spread to your lemon tree.
As devastating as anthracnose may be, you can easily control it. Simply remove all plant debris from the base of your lemon tree. From there, you’ll need to prune and destroy all infected wood, twigs, and leaves.
The correct watering methods and lemon tree care help prevent anthracnose from occurring. You may want to use some copper-based fungicides and neem oil to prevent the fungus from taking root. But, these do affect beneficial insects, in some cases harming them and stopping them from taking up residence in your garden, so use them as a last resort.
5. Brown Scabs – Lemon Scab
It seems that fungal diseases love lemons as much as we do. Another to keep a close eye out for is lemon scab or citrus scab.
This fungal infection doesn’t harm the fruit and you can still eat them – they just don’t look great. But, if left completely unattended, your tree’s health deteriorates, reducing its ability to fruit.
As its name suggests, lemon scab spots look like ugly brown scabs. At first, they look like small pustules, and as the disease spreads, it takes on its scab-like appearance.
Lemon scab affects twigs and leaves too.
Twigs and leaves become misshapen and withered. You’ll find that your lemon tree will seem stunted and bushy if it’s infected with lemon scab.
As with other fungal infections, wet and humid conditions are perfect for this disease to thrive and take hold.
Your first line of defense, as always, is to maintain good garden hygiene and correct watering methods. Many suggest culling the infected tree as an alternative to harmful fungicides that may damage other plants in your garden.
6. Yellowing Leaves – Chlorosis
If you notice yellowing on your lemon tree leaves, you’ve may have a case of chlorosis on your hands.
Many factors can lead to the yellowing of leaves. Sometimes it could be poor drainage or soil that is too alkaline. Compacted soil and damaged roots could also lead to chlorosis.
Sometimes though, you’ll notice yellow veins streaking through your lush green leaves. Simply named yellow vein chlorosis, this form of chlorosis could mean your tree has a nitrogen deficiency. Increase the levels of nitrogen on your next fertilizing day and your tree will take care of itself.
But, yellow vein chlorosis can also be a result of trauma experienced by your lemon tree. Physical damage from garden tools, pests, and diseases could cause this phenomenon.
Always be careful with your gardening equipment, maintain high levels of garden hygiene and care for your lemon tree correctly. Ensure you’re managing pests and diseases too. Chlorosis, especially if caused by trauma, could lead to fruit drop and defoliation.
7. Silver Streaks On Leaves – Citrus Leaf Miner
Aphids are always a major concern in citrus gardens, but when it comes to lemon trees, they’re not the only pests to look out for.
Citrus leaf miners are small moths native to Asia. Adult moths aren’t the concern – their larvae are. These small pests get their unique name because they tunnel across citrus leaves, leaving silvery trails streaking across your lemon tree leaves. Eventually, these leaves become distorted, and the growth of younger leaves can be affected.
Adult citrus leaf miners are minute and often go unnoticed. These silver moths have a black spot on the tips of their scaled wings. Larvae are equally as small but have a glass-like greenish hue.
Female moths tend to lay their eggs on the underside of leaves. Pupation occurs in under a month and inside the leaf margin. In as little as a week, you’ll notice their trails all over your leaves.
It’s important to note that these little pests don’t attack the fruit itself, just the leaves. Young lemon trees are especially vulnerable though, with the citrus minor infesting young foliage. If left unattended, the growth of your lemon tree will be affected.
The best way to deal with citrus leaf minors is to introduce beneficial insects. Not all bugs are bad. Some munch away at the pesky insects destroying your plants. Parasitic wasps and spiders are great insects to introduce into your garden. They can eliminate the majority of larvae and pupae in a matter of days.
Lemon trees are great additions to any garden capable of accommodating them. While they may seem to come with a plethora of problems, don’t let that stop you from growing one. They’re easy to care and they grow and fruit quickly. And, whether it’s a fungal disease, deficiency, or pest, there is usually a solution to the problem.
If you’re interested in adding more fruit trees to your property, check out some of these great dwarf options. Or maybe you don’t have room outdoors, you can still grow fruit trees indoors.
Lemon tree, diseases, species, care
Lemon tree diseases and pests
Lemon tree belongs to the Rut family of the genus Citrus. Incredibly, this beloved and healthy fruit is an accidental hybrid that originated in India in the natural environment. It is not difficult to grow this plant at home, it is enough to know some subtleties of care and choose the right plant variety.
Lemon tree varieties
Indoor low-growing and fruit-bearing plants include the following types of lemon tree:
Each of these species can be grown even in a small apartment. But sometimes a variety of diseases affect the lemon tree, and it is important to know how to get rid of them quickly.
Lemon disease causes
A number of factors lead to many diseases of this plant:
- Incorrect watering, lighting, temperature, top dressing, pruning.
- Infection from poor quality soil or a pot previously used for another plant.
- Infection with parasites during the growing season.
- Infection with bacteria from insects.
- Introducing viruses from outdoors during ventilation (extremely rare).
Lemon diseases and methods of combating them
Lemon trees often get sick due to improper care. In this case, in order to cure the plant, it is enough to correct some points of care.
If the leaves of a lemon tree have faded, turned pale green or yellow, the plant most likely lacks light or nutrients. Move the lemon to the east window and fertilize the soil. Thin shoots and small leaves also indicate a lack of light.
In case of leaves and buds falling, watering the tree should be increased, the leaves should be sprayed, since most often this problem is associated with a lack of moisture and drying out of the soil. Drying and curling of the leaves, as well as darkening of the tips of the leaves, if they turn brown, are associated with the same reason - the air is too dry in the room.
Are you all waiting for flowering, but it never comes? Perhaps your lemon is growing in a cramped pot. Try repotting the plant and fertilizing it.
Principal pests of the lemon tree
- Spider mite
Pale green small parasites that stick to young leaves in whole colonies, causing them to curl and die. First, the aphid sucks the juice from the inside of the leaf, and then spreads to the branches. The parasite can enter the house along with another houseplant or with a bouquet of wildflowers. To get rid of aphids, treat the plant with an insecticide, diazmnon will do. From folk methods, an infusion of garlic helps well. Take seven heads of peeled crushed garlic in a bucket of water and leave for a day, then strain and spray the lemon. If aphids have infested the roots, the plant needs to be repotted. At the same time, completely get rid of the infected soil, and dip the lemon roots into the insecticide solution.
The parasite takes up residence on the plant as a larva. Adults stick to the bottom of the leaves and remain motionless covered with a waxy coating. Infection with a scab is manifested in drying out and a strong weakening of the plant. You can get rid of the parasite using the same methods as in the fight against aphids. And also with soapy water. To do this, two tablespoons of soap should be diluted in a liter of water and thoroughly treat the affected areas. Then we send the lemon under a warm shower and thoroughly rinse off the soap. The procedure should be repeated after 2-3 days.
The parasite settles on young leaves, causing them to dry out and curl up. Sick leaves are covered with small cobwebs, by which you can recognize the tick. This parasite settles only on those plants that stand in dry rooms. Therefore, it is best to deal with it with abundant spraying. You can spray the lemon with a 1% solution of boric acid. As a rule, this procedure helps to kill the tick the first time, but if the parasite has not gone away, repeat spraying with the solution after a few days.
information articles from the company "August"
Among the trees that are grown at home, the lemon is unpretentious. This small tree is quite easy to care for, aesthetically pleasing in appearance and, under the conditions of maintenance, usually remains strong and healthy. But, like any houseplant, lemon is susceptible to a number of infectious diseases. Diseases of the lemon tree spoil its appearance, weaken the roots and leaves, and in advanced cases can even lead to the death of the plant. In order to prevent such an outcome, you need to carefully monitor the condition of the lemon, take care of it competently, and begin treatment at the first appearance of suspicious symptoms.
Causes of diseases
Most often, a lemon tree is sick if:
- it did not have time to get stronger after a transplant or other disease;
- it is not properly cared for, the plant has poor immunity;
- contaminated land was used for landing;
- an infection - a virus, bacterium or fungus - was accidentally brought into the ground on a shovel or other garden tool.
A healthy, strong and strong lemon gets sick less often: the plant's immune system helps to cope with disease-causing agents. He gets sick if the concentration of pathogens around greatly exceeds the norm, or in case of problems with immunity. The diseases themselves can be divided into several groups.
Infectious diseases. Infections are caused by fungi, bacteria and viruses that live in the soil and sometimes in the air, eg fungal spores can be carried by the wind. Most often, a home plant becomes infected if the pathogen gets on a garden tool; infection rarely occurs during airing.
Pests . These include insects and arachnids that settle on a lemon and begin to feed on its juices. This weakens the plant, depresses its immunity, causes a lack of nutrients. The tree becomes more vulnerable to infections, in addition, pests themselves can carry diseases, infecting the lemon with them.
Weakening of immunity. Sometimes the stunted and diseased condition of a tree is not caused by some infectious agent or pest, but by a poor condition: lack of nutrition or moisture, lack of top dressing. Such a plant is more likely to get sick and become infected more easily, pests love it more. This condition is treated with competent and thoughtful care.
Major diseases of the lemon tree
Gommoz . It is also called gum treatment. This is the state in which the lemon releases gum, a reddish, sticky liquid that is often confused with resin. Gum disease occurs due to mechanical damage to the cortex or infectious diseases, fungal, viral and bacterial. Some sources separate simple gum disease and gummosis: the first is a reaction to mechanical injury, the second is the outflow of gum caused by infection.
Determination of the cause and treatment of damaged areas will help to combat this phenomenon:
- the wound will need to be cleaned down to healthy tissue;
- the cut will need to be disinfected and treated with special preparations that will help the damaged area recover faster, then cover it with garden pitch.
Even if the cause was not a disease, but an ordinary injury, treatment should not be neglected: a wound on the bark of a tree can lead to infection. The damaged area is vulnerable to disease.
Sooty fungus. This is a fungal disease commonly referred to as black mold due to its characteristic appearance. The fungus infects the leaves: they are covered with dark spots, similar to soot, which increase in size and spread. Occurs against the background of pest infestation: many insects secrete sticky sweet substances that contribute to the appearance of the fungus. The disease does not destroy the tissues of the tree, but interferes with photosynthesis, as a result, the lemon grows poorly and receives less nutrients. Since the main reason for the appearance of soot fungus is pests, in order to completely eliminate the disease, you first need to get rid of them and clean the tree of traces of their secretions. After that, the fungus, which feeds on the waste products of insects, will disappear. Fungicide treatment may also be required.
Scab . This disease is caused by a fungus that infects the leaves and spreads fairly quickly. In diseased areas there are hard convex spots of dark color. They are round in shape, with time they begin to become covered with plaque. In addition to leaves, scab also affects other above-ground parts of the plant, such as fruits: spots, red and orange dots, and plaque also appear on them. If measures are not taken in time, the fungus can completely destroy the plant, so treatment should be started at the first symptoms.
- Affected areas may need to be cut and removed so that they do not infect other parts of the tree.
- The lemon itself will need to be treated with fungicides - drugs that fight fungal diseases.
Scab is especially active at high humidity, in such cases it is recommended to check how optimal the conditions for keeping a lemon are.
Root rot. The disease is caused by a fungus that lives in the soil: it manifests itself with excessive moisture or stagnant water. The disease is very dangerous, spreads rapidly, depriving the plant of the opportunity to eat normally, and eventually completely destroys the tree. You can suspect the disease if the lemon stopped growing, began to wither, leaves began to fall off it, while there are no signs of infectious diseases of the aerial parts, as well as insects. It will be necessary to act urgently: the lemon will need to be transplanted from infected soil to clean and treated with modern fungicides. Root areas affected by rot will have to be removed, cuts should also be treated with plant injury healing agents, such as charcoal. If the disease is started, the root system can completely rot, after which it will not be possible to save the lemon.
Warty . It is also a fungal disease that looks like scab, especially in the early stages. The difference is that the spots eventually turn into hard warts that cover the entire plant. Over time, the disease can lead to the death of a lemon tree, requiring urgent treatment with fungicides. You will also need to remove all damaged areas and burn them.
Products "August" for the treatment of lemon diseases
- Pure Flower. This is a systemic fungicide that fights fungal diseases in ornamental crops. Allows you to get rid of spots and gray rot, accumulates in tissues and protects the plant for 2 weeks. It has a preventive and curative effect. 2 or 4 ml of the agent, depending on the disease that is supposed to be fought, is dissolved in 10 liters of water and the affected plant is sprayed when the first symptoms appear. May require 2-4 treatments spaced 14 days apart.
- Healthy Earth. To make sure that there are no pathogens in the soil, use the Healthy Earth preparation. The product includes two fungicides that destroy possible pathogens in the soil and minimize the chance of the plant becoming infected. Soil treatment is carried out with a solution of 2 ml of the agent per 1 liter of water before or after planting. Prevents root rot, lasts up to 30 days.
Lemon tree pests
Lemon can get sick not only because of fungi or bacteria. The cause can also be harmful insects and arachnids that suck the juices out of it and contribute to the development of infections. Pests multiply rapidly, and if they are not dealt with, over time they are able to completely destroy the plant - you will have to act quickly.
Shield . These small insects are covered with a shield - a protective shell that makes them invulnerable to contact agents. Their bodies are up to 5 mm long, brown, rounded. The scale insect sticks mainly to the places of attachment of the leaf cutting to the branch: there they can be found most often. Some recommend using drugs only to kill the larvae, and collect adult insects from the tree with your hands. But you can also destroy insects with the help of Aliot. It has a triple action: in addition to the contact mechanism of work, the agent affects the respiratory and digestive systems of the pest. The pesticide destroys both adults and larvae, allows you to cope not only with scale insects, but also with a number of other pests. You will need to spray the tree with a solution in the proportion of 10 ml per 10 liters of water. Pests will die within 2 hours after treatment, the tree will be protected for another 7–14 days.
Spider mite. This tiny arachnid is difficult to see with the naked eye: the infestation is identified by the characteristic cobweb that appears on the plant. If you look closely, among the cobwebs you can find small running dots - ticks. They mainly feed on the juice of young shoots, as a result, they gradually die off, the plant withers and dries out. If you neglect the treatment of a lemon tree, it may die. The drug "Kleshchevit", specially designed to destroy harmful arachnids, will help fight the tick. This is an acaricide of contact-intestinal action, which leads to the death of the pest within 3-4 days after treatment. Ticks stop eating within 6 hours after spraying. The drug must be dissolved in water in a ratio of 2 ml / 1 liter. In case of a massive lesion, up to 4 treatments may be necessary.
Aphid . A small insect only up to 5 mm in size feeds on plant sap, secretes honeydew, which, in turn, can attract ants or become a haven for infections. Aphids are most often green in color, a different color is less common. The insect sucks the juices from the lemon tree, as a result it receives less nutrition, gradually dries up and dies. Aphids multiply rapidly and are able to soon infect all indoor plants: some pests can fly. At home, the only measure to combat them is insecticides. The preparation "Biotlin" of the company "August" was developed specifically for the destruction of aphids of various species, which lives on various horticultural, horticultural and ornamental crops. This systemic remedy works both by contact and by ingestion, killing both larvae and adult insects in a few hours. The protective effect lasts for 2-3 weeks.
