Neem benefits

Neem is an excellent organic pesticide / repellent with a broad-spectrum pest control activity and is proven effective against 350 species of insects which are extremely damaging to agricultural crops. It works on chewing and sucking insects and interrupts their basic instincts to eat, breed and lay eggs. Eating is interrupted soon after neem is applied, while other behavior disruptions may occur up to a few days later, if the insect is not already dead from starvation. Neem is non-toxic to crops, humans and animals and birds can eat debilitated insects with no ill-effects. Neem does not destroy natural predators and parasites of pests thereby allowing these natural enemies to keep a check on the pest population. It is biodegradable; does not harm beneficial insects and insects do not build-up a resistance. Just one litre of Neem Oil is required per spraying for the protection of two & a Half acres of crop. Use 20 ML / four teaspoons of neem oil to produce 4 liters /one gallon sprayer.

Apply neem oil only in indirect light or in the evening to avoid foliage burning and to allow the treatment to seep into the plant. Also, do not use neem oil in extreme temperatures, either too hot or too cold. Avoid application to plants that are stressed due to drought or over watering. Avoid spraying neem oil solution when the temperature is over 90 F. Spray during the cooler periods of the day, early morning or evening. If you use neem spray during hot weather, it can cause leaf curling. Using neem power, the mixing ratio is 20 gms power to 10 lts of water and 3gs of bar or liquid soap or lemon juice to emulsify the oil so it will mix with the water. Let mix overnight or two then stain with finest cloth to prevent clogging of sprayer.

The oil has a half-life of three to 22 days in soil, but only 45 minutes to four days in water. Only mix the quantity of neem solution needed for immediate use. Dispose of any leftover neem solution after you finish spraying. Do not keep it for later use, because it begins to break down within a few hours. Mix a new batch of fresh solution each time you need to spray. Neem is most effective when used to protect plants prior to infestation. To respond to infestation, repeat the spraying once a week for five weeks.

The Neem Leaf power is diluted and is use for a spray pesticide on average 2 -3 times during the year. It takes 2 kg of diluted Neem power to spray one acre for the year. To make five litres of spray use about one kilogram of fresh neem leaves. Put the leaves into a pot and add five litres of water. Boil the mixture until the green color is gone from the leaves. When the green color is gone it means that the part of the leaves that affects the insects has gone into the water. Let the water cool overnight. The next day, remove the leaves or filter the mixture through a fine cloth. If you find that this spray is not strong enough, try using two kilograms of leaves in five litres of water instead. Also, you can use cold water and crush the neem leaves before putting them in the water. The next day, remove the leave power by filtering the mixture through a fine cloth. Use lemon juice of liquid soap as an emulsifier.

Neem Oil is a very cost – effective means of pest control. Just 1.25 litres of Neem Oil is required per spraying for the protection of 1 hectare of crop (16 fl.oz. per acre). Add 10 milliliters of any suitable emulsifier to 50 milliliters of Neem Oil and mix with water. Local price of neem oil per liter approximate. ksh 2,700 and neem leaf power 600 a kg. The global market for neem is booming alongside a growing interest in natural and organic products around the world. The neem market [1] is expected to grow from $653 million in 2015 to $1.8 billion in 2022, at a compound annual growth rate (CAGR) of 16.3%.

The majority of the neem extract market is currently based in the Asia-Pacific, with significant demand now coming from the United States, Spain and Italy. The major factors driving the global neem market are the crop’s efficient, safe and cost-effective applications in organic agriculture. 

  • The global neem extract market is expected to grow from $653.7 million in 2015 to $1.87 billion in 2022 at a CAGR of 16.3%.
  • Among all application areas, the agriculture segment accounted for the highest share of 40% in the total revenues of neem extract products.
  • Used extensively in the manufacture of high quality and organic cosmetics (due to their efficiency, low toxicity and lack of side effects), this segment accounted for 30%
