botanical insecticide | azadirachtin is a botanical insecticide extracted from neem tree and is recognized as the best biological pesticide in the world today. It is characterized by high efficiency, low toxicity, broad spectrum, less interference to natural enemies, no obvious vertebrate toxicity and crop damage, and rapid degradation in the environment. Azadirachtin has the effects of anti-feeding, avoidance, absorption and inhibition of growth and development. It mainly acts on the endocrine system of insects to reduce the release of ecdysone; it can also directly destroy the epidermal structure or prevent the formation of epidermal chitin, interfere with respiratory metabolism, and affect the development of the reproductive system. The mechanism of action is special, the action location is many, and the pests are not easy to develop drug resistance. The content of azadirachtin in seeds is about 0.01%. Azadirachtin mainly exists in the seed nuclei of Neem and Neem, and even factors such as growth period and natural conditions will affect the content of active ingredients. Azadirachtin has a strong anti-feeding and insect growth regulation effect, and can be absorbed by plants. It has antifeedant activity at 0.1 mg/kg, and 0.35 mg/kg can make armyworm antifeedant. Azadirachtin has a strong anti-feeding effect on brown rice lice and can prevent oviposition. Safe for people, animals, etc. |
toxicity | azadirachtin is safe for humans, animals, birds and bees, does not affect predatory and parasitic natural enemies, and is easy to degrade in the environment. |
action characteristics | azadirachtin has many effects on pests, such as anti-feeding, anti-avoidance, poisoning and affecting insect growth and development, and has good internal absorption and conduction characteristics. The azadirachtin preparation is applied to the soil and can be absorbed and transported to the stems and leaves by the roots of cotton, rice, corn, wheat, broad beans and other crops, making the whole plant resistant to insects. The agent can effectively control gypsy moth, Japanese scarab, Spodoptera spout, Spodoptera, Spodoptera litura, Spodoptera litura, vegetable moth, leaf miner, meadow borer, desert locust, migratory locust, corn borer, rice brown planthopper and other pests. Usually 2 ~ 5kg of neem leaves are added to every 100kg of grain to control grain storage pests. |
application | neem preparation can effectively control various pests, such as gypsy moth (Lymantria dispar), Japanese golden tortoise shell (Popillia japonica), Spodoptera robusta (Heliothis virescens), Spodoptera robusta (Heliothis zae), Spodoptera litura (Prodenia litura), Plutellamaculipennis moth (nubilalis), leaf miner (Agromyzidae), grass moth (Spodoptera frugiperda), desert locust (Schistocerca gregaria), African locust (Locusta migratoria migratorioidis), corn borer (Ostrinia), rice brown planthopper (nilaparvata lugens), etc. 0.1 ~ 1% nuclear ethanol extract spray is commonly used. Add 2 ~ 5kg of neem leaf powder per 100kg of grain to control grain storage pests. |
control object | azadirachtin can control various crop pests. For the control of red spiders, rust spiders, aphids, leaf miner, whitefly on citrus crops; diamondback moth, cabbage worm, tobacco worm, cotton bollworm, tea green leafhopper, tea yellow thrips and various locusts on vegetables Good control effect. (1) using 0.3% azadirachtin emulsifiable concentrate 2.25~4.5g (active ingredient) per 100 square meters, mixed with water spray, can effectively control diamondback moth of cruciferous vegetables. (2) to control pests on citrus, it is recommended to use 1000~1300 times of 0.3% azadirachtin emulsifiable concentrate with an interval of 8~10 days. water spray can control red spiders, rust spiders, aphids, leaf miners and whiteflies on citrus crops. |
precautions | (1) azadirachtin is a plant-derived insecticide with slow efficacy and should be used for prevention before larvae occur. Azadirachtin has a long efficacy. (2) It cannot be mixed with alkaline fertilizers and pesticides, nor can it be diluted with alkaline water. |
