Problems solved by technology

[0002] Traditional pesticides such as "DDV", "Omethoate", and "Monocrotophos" that have lasted for many years are all chemical oils and emulsions made of chemical raw materials. These chemical insecticides have many advantages in terms of efficacy and environmental protection. The shortcomings are gradually discovered by people in practical application, and they can no longer meet the needs of modern agricultural production.
