Problems solved by technology

[0002] Because people rely solely on the use of a certain type of pesticide for a long time, pests are prone to develop resistance, resulting in a sharp increase in the amount of chemical pesticides used, polluting the environment, and killing a large number of natural enemies of pests. It will produce drug resistance, lead to rampant damage of pests, and easily cause human and animal poisoning
[0003] Azadirachtin is a compound derived from the plant Neem. It has excellent insecticidal activity and is effective against almost all agricultural pests. It degrades quickly in the environment and does not harm natural enemies and other non-target organisms. It is a universally recognized Excellent biopesticide, its disadvantage is unstable
Flufenuron is a kind of insecticide with high efficiency and low toxicity, especially for lepidopteran pests with high efficiency and strong selectivity.
