Plants as "pesticide" use absolutely no pesticides

In crop production, pesticides are impossible or lacking, but the problem of pesticide residues has caused headaches for farmers. I want to completely remove pesticide residues, unless there is no pesticide. I think many people here think that this is heaven and night, in fact, life. There are many plants that can also act as “pesticides”. Let's learn together.

The above are several plants that can act as pesticides. To learn more about pesticides, please pay attention to the Chinese pesticide network.
