technical field [0001] The invention relates to an insecticide, in particular to a plant insecticide, its preparation method and application. Background technique [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. [0003] Based on the above background, it is necessary to propose a new type of plant insecticide on the basis of the prior art, so as to break through the limitations that exist in the current practice. Contents of the invention [0004] The object of the present invention is to provide a new type of plant insecticide, which not only has good insecticidal effect but also is friendly to t...
