Most infestations are killed by azadirachtin without hurting pollinators or useful creatures like earthworms or predator species. It will, however, aid in the treatment of a variety of bacterial and fungal illnesses, including some types of root rot.

When NOT To Use Neem Oil

While neem is non-toxic and is commonly used in toothpaste, it is generally acknowledged that you should not apply it to a food plant on the day it is harvested.

You can use a foliar spray the day before harvest or soil soaks. If you don’t apply it on the day of harvest, you’ll consume less.

Another important requirement is to test a small portion of a plant one day prior to utilizing neem oil goods.

Even natural materials can cause allergies and sensitivities in plants, just as they can in humans.

You can check for evidence of chemical burns or allergic responses by testing a small section of the plant first.

You may only need to test once if you use neem on a regular basis. However, if you haven’t applied neem oil on the plant for a long time, you should always retest it.

You should stop using neem products on that plant right once if you see an adverse reaction during testing or regular use.

What Neem Oil Does

Neem oil includes at least five recognized insecticidal compounds in its pure form, the most important of which is Azadirachtin.

The Azadirachtin is then removed from raw neem, and the clarified hydrophobic neem oil that results becomes a contact poison, blocking the airways of any insects that come into touch with it.

This makes it effective against a variety of fungi, including sooty mold, and it can even assist your plants resist root rot to some extent.

Neem Oil Toxicity

Despite the fact that neem oil is generally harmless and is utilized in a variety of healthcare items, some people remain concerned.

  • You or a family member is expecting or breastfeeding a child (Neem soil soaks and cakes)

In little children, azadirachtin has been known to produce seizures and other serious side effects. There is some evidence that it can cause miscarriage or other pregnancy issues.

Honey, like many other natural compounds, carries similar hazards throughout pregnancy and infancy, so be cautious, not alarmed.

Neem oil does not harm bees, ladybugs, or other beneficial insects when used properly.

However, any sprays should be applied at twilight or morning to prevent injuring these garden pals.

Always remember that neem oil is non-discriminatory, but it also evaporates quickly when applied topically, so timing is crucial.

Neem Oil Foliar Spray

Simply add 1 teaspoon of Dawn dish soap or pure castile soap per gallon of water to emulsify the water.

After that, add 2 teaspoons of clarified hydrophobic neem oil to a spray bottle or a garden sprayer.

Spray the entire plant, paying special attention to the undersides of leaves and any crevasses.

Harvest your crop after waiting at least one full day following the last treatment and properly washing it.

This will not only ensure that there is no liquid neem stuck in the crevasse, but it will also remove any soap residue.

While foliar sprays are the safest alternative, they do take more time and work than other options.

What Concentration Should I Use?

Clarified neem is available in a variety of concentrations, ranging from.5% to 3%.

The various numbers show how much Azadirachtin is left, and each concentration excels at distinct tasks:

  • The most common dosage used for preventive and mild infestations is 1% percent.
  • For heavy infestations where the 1% percent isn’t strong enough, the 2% percent is employed.

Although there are additional percentages, these are the ones you’ll utilize the most.

Neem Oil Soil Soaks

Neem soil soaks, the polar opposite of foliar sprays, are the simplest to use but the most effective.

A soil soak is created in the same way as foliar sprays, with the exception of two tablespoons of 100% cold-pressed raw neem oil per gallon.

Pour 2 to 4 cups of the mix straight onto the soil surrounding the plant’s roots on a day when you would typically water the plant, being careful not to splash the plant itself.

In the soil, neem can persist anywhere from 3 to 22 days, however the majority of it is absorbed by the plant roots.

After being absorbed, neem becomes a systemic insecticide that can last up to 22 days in the plant.

Only pests that gnaw or penetrate the plant will be exposed since it mixes with the sap.

There is no proof that this method contains neem in fruits like tomatoes or other berries or vegetables, but it is better to err on the side of caution if needed.

Neem Cakes

Neem cakes are the materials left behind from the production of neem oil, and they are perhaps the most underrated variety of neem.

Only trace amounts of oil are present in the cakes, which are employed as a fertilizer with an NPK of 4-1-2.

Follow any product directions, and keep in mind that neem cakes are only effective against ground-based pests like grubs.

Because the cake contains very little neem oil, it should not pose a risk to infants.

However, there is no solid evidence that any neem makes its way into the produce from neem cakes, so proceed with caution.

Is it possible to overuse neem oil on plants?

Yes, too much neem oil can harm plants by forming a coating on the leaves’ surface. The leaves are suffocated and unable to produce food as a result.

The active element in neem, azadirachtin, is made up of liminoids, which are steroid-like chemicals. When insects consume neem-coated leaves, the liminoids disturb regular hormone production and processing, causing some insects to lose their appetite and disrupting normal reproduction, maturation, and molting processes in others.

Neem, when used as a spray, will suffocate pests on contact and prevent eggs from hatching. Neem oil comes in two forms: concentrate (which must be blended with water) and ready-to-use portable spray bottles. It’s safe to use on both ornamental and food plants, and it can be sprayed on herbs and vegetables right up until harvest time. Applying neem oil to a drought-stressed plant might cause the foliage to burn, so make sure the plant is well-watered before applying it.

How often should I use neem oil?

Neem oil can damage some plants, especially if it is applied heavily. Before spraying a full plant, test a tiny section and wait 24 hours to observe if any harm has occurred to the leaf. The plant should not be affected by the neem oil if there is no damage.

To avoid foliage burning and to allow the treatment to penetrate into the plant, use neem oil only in indirect light or in the evening. Also, neem oil should not be used in extreme temperatures, such as those that are too hot or too cold. Avoid using it on plants that have been stressed by drought or overwatering.

Neem oil insecticide, applied once a week, will help eliminate pests and prevent fungal infections. Apply as you would other oil-based sprays, being sure to completely coat the leaves, especially where the pest or fungal problem is the severe.

Benefits of Neem Oil on Tomatoes

Is it okay to use neem oil on lettuce?

When it comes to my food plants, I prefer to use natural insecticides whenever possible as an organic grower. I’ve read a lot about neem oil and how effective it is at preventing insect infestations and fungal diseases. However, I’ve read conflicting accounts concerning its safety. So I decided to investigate it further and discover the truth.

Is neem oil safe to use on plants? Yes, neem oil is completely safe. For nearly 400 years, neem oil has been used as a pesticide on plants in India. Plants, vegetables, and people who eat them are not harmed when neem oil is applied. When spraying neem oil, take precautions because some people may have an allergic or respiratory reaction.

It turns out that neem oil is a fantastic weapon in the war against garden pests. It isn’t a panacea for all problems, but it is a useful tool to have in your toolbox. Neem oil contains a natural pesticide that can only be found in neem. It is non-toxic when used as an insecticide. The type of neem utilized, as well as the application method, are important. Before you start using neem oil for garden insect infestations, here’s what you should know.

If neem oil is sprayed on the plants, such as lettuce and kale, can I harvest and eat those greens right away, or do I have to wait a certain length of time?

It’s fine as long as the greens are fully cleansed. Spraying the oil on the kale before harvesting, on the other hand, makes no sense. First, harvest the kale, then spray. On plant leaves, neem oil degrades after 2-5 days. Spraying long before you plan to harvest is the perfect situation.

Is neem oil safe for humans, dogs, and cats?

The Food and Drug Administration (FDA) considers neem oil to be generally safe for people. Toothpaste, shampoos, and soaps include neem oil extracts and components. However, the goods are not completely concentrated neem and are not identical to what is used in insecticides.

If not used appropriately, neem can be hazardous. Neem oil applied correctly to plants and vegetables will not produce dangerous levels. However, all treated veggies should be washed before consumption. The oil can be removed by thoroughly washing with water.

Neem oil can irritate the skin or induce an allergic reaction. When working with neem, extreme caution is advised, such as donning protective clothes.

The American Society for the Prevention of Cruelty to Animals (ASPCA) does not consider neem to be poisonous to dogs or cats. Aquatic creatures are somewhat harmful to neem oil.

Which pests does neem oil kill?

Only soft-bodied insects, larvae, and eggs are affected by neem oil. It is not effective against hard-bodied insects such as beetles, but it is effective against their larvae. It can also be used to treat white powdery mildew.

Aphids, mealybugs, caterpillars, spider mites, lace bugs, thrips, whiteflies, cabbage looper, leafhoppers, leafminers, and beetle larvae are just a few of the pests that neem oil can help with.

Furthermore, we exult in our sufferings, knowing that suffering produces endurance, which produces character, which produces hope, which does not put us to shame, because God’s love has been poured into our hearts through the Holy Spirit who has been given to us.

How does neem oil work?

Neem oil has two purposes. The sprayed oil coats the leaves of the plant. The oil seeps into the insect’s respiratory system and suffocates it when it consumes the leaf.

Azadirachtin, a natural pesticide, disturbs insect systems. They are unable to forage, fly, or mate because their hormonal functions are disrupted, and they will finally perish.

Neem oil does not work right away. It takes around 72 hours for the insects to entirely perish. Results can occasionally be apparent in as little as 24 hours, but the entire effect takes a little longer.

Does neem oil harm beneficial insects?

Because they don’t eat the treated leaves, beneficial insects like bees, butterflies, and ladybugs are unaffected by the insecticide. It’s possible that they’ll land on the leaves, but this isn’t detrimental. If butterflies or ladybugs lay eggs or larvae on the leaves, they may be harmed. Use it sparingly and only on pesty insect-infested plants; don’t spray it all over the place.

Neem oil kills all insects when applied because it blocks their airways and suffocates them. Apply neem oil in the morning before butterflies and bees emerge to avoid killing helpful insects. Also, just spray the plants that are afflicted to reduce the risk of harm.

Which neem oil product is best?

There are various ready-to-spray neem-based pesticide products at the garden store. The majority of these contain a neem oil hydrophobic extract. Parts of neem oil are mixed with alcohol or a chemical to make this extract. Azadirachtin, a natural pesticide, isn’t included. Don’t waste your time with these items. They don’t do anything different from vegetable oil.

Cold-pressed 100 percent neem oil is the best neem pesticide. This contains all of the neem seed’s characteristics, including azadirachtin. It must be combined before use, although this is a straightforward procedure.

Here’s a link to Amazon for the 100% Cold Pressed Neem Oil that I used in the above photos.

How to Mix Neem Oil

*You can use up to 2 tablespoons of neem oil, but it’s better to start with the least amount.

  • To ensure that the mixture is emulsified, add all of the ingredients in the container and shake vigorously (combined). The dish soap serves this purpose.
  • If the oil begins to separate from the water, add a little more dish soap and shake the container again. For at least 30 seconds, the mixture should be emulsified. If necessary, add additional dish soap, but don’t go overboard because it will influence how the oil sticks to the leaves.

How to Apply Neem Oil

  • Wear long-sleeved shirts, long pants, and a face mask to protect yourself.
  • Test the mixture on one leaf to make sure it won’t harm the plant. Some plants’ leaves may be damaged by a mixture containing too much soap or oil.
  • Spray the entire plant, especially the areas beneath the leaves where eggs and larvae are most likely to appear.
