How to use theNeem oil in agriculture
There are many plant protection products used in agriculture and based on the active ingredient of Neem, azadirachtin. L'Neem oilit can be successfully used against gray apple aphid, various lepidoptera that attack citrus fruits, some thrips and whiteflies. It is also effective on cicadellidae and the Colorado potato beetle. How to use theNeem oil in agriculture?
Like fungicide and broad spectrum pesticide (you can therefore also use it as an insecticide for plants affected by fungal diseases)you just need to mix it with lukewarm water in a 1/100 ratio. That is to say, for every 100 liters of natural plant insecticide produced sinceNeem, only one liter of oil and 99 liters of warm water must be used.
The natural insecticide obtained can be sprayed directly on the leaves to be treated, possibly at sunset (the active ingredient is photosensitive and may lose its effectiveness if used in full sun). The treatments can be repeated every 10 - 15 days until the infestation has completely disappeared.
In case of very acute infestations, you can make a smaller dilution using 2 liters ofNeem oilfor every 98 liters of warm water (2%). If you want to use theneem oilfor preventive purposes you can make dilutions with a concentration of 5% (500 ml of Neem oil for 99.5 liters of warm water).
Neem oil in organic farming
L'Neem oilis allowed in organic farming. To fully exploit the anticryptogamated effect, the Neem oil solution should be stirred continuously even during use. I remind you that the oil is immiscible in water and to obtain a more homogeneous application it will be necessary to use an emulsifier. As an emulsifier, I recommend using the Lavanoci decoction or a few drops of dishwashing liquid.
Neem oil in agriculture to eliminate aphids
L'Neem oilcan be an excellent natural remedy for aphids. A foliar treatment to eradicate an aphid infestation can be performed with:
- 100 ml of Neem oil
- 100 ml of ethyl alcohol
- 10 liters of warm water
With the solution obtained, plants in full vegetation grown in about 10 square meters of surface can be treated. L'Neem oil it is a bit difficult to "dissolve" in water and alcohol, so even in this case it will be necessary to stir the mixture continuously, even during application (unless you decide to use an emulsifier). The treatment must be repeated at least once 20 days after the first application.
Where to buy Neem oil
Neem oil is a product with multiple properties, however it is not very widespread and can only be found on sale in shops specializing in the sale of natural products, or in more specialized agricultural consortia.
It is not particularly expensive especially if you buy it online but be careful! In ecommerce, generally, there is a form ofneem oilrefined and suitable for cosmetic use, this shape is perfect for agricultural use but is more expensive.
To use theneem oil in agriculture, as an insecticide, you can buy crude neem oil, much cheaper. Just think that,"To this Amazon page" 1 liter of pure neem oil is offered at a price of 16.95 euros.
Note: The manufacturers claim that it can also be used for cosmetic use, however, having tried both this oil and a neem oil for cosmetic use, I can say that there is a slight difference. I specify that our website has no connection with producers, so feel free to choose the neem oil you prefer! :)
Azadirachtin in agriculture
Not just neem oil, you can buy preparations formulated directly from the active ingredient extracted from neem oil. It is clear that these are more effective products. Azadirachtin is allowed in organic farming and it is only the active substance responsible for the antifungal and antiparasitic properties of neem.
Also in this case, for the purchase, you can contact garden centers, agricultural consortia or take advantage of online sales. For a complete overview of the products available, I refer you to"This Amazon page".
Speaking of oil to use in the kitchen, however, we recommend the article onExtra virgin olive oil. You may also be interested in the article on Nematocides
