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, which not only increases production costs, but also kills a large number of natural enemies of pests and pollutes the environment, resulting in Rampant damage from pests
[0003] Rotenone is a compound derived from plant rotenone root and edamame leaves. It has excellent insecticidal activity and is effective against most agricultural pests. The dosage is low and it degrades quickly in the environment without harming natural enemies and other non-target organisms. It is an excellent biopesticide, but its disadvantage is that it is not systemic

Abstract

The invention discloses an agricultural chemical preparation which has elliptone and pymetrozine, and is mixed by elliptone with the weight proportion 0.05-70%, pymetrozine with the weight proportion 0.5-70% and residual assistant agents. The invention utilizes the efficiency-increasing complementary function between the toxicity performance of the active component of elliptone and the strong inward-absorbing performance of pymetrozine, and attains the aims of making up the shortcoming of single-dose agricultural chemical, overcoming the drug resistance of pests, improving the effect of the preparation, enlarging the employing scope of the preparation and prolonging the persistent period of the preparation. The invention has important sense in developing and applying natural pesticides, has little damage to biological environment and is beneficial for protecting safety of people and animals.

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a compounded pesticide of rotenone and pymetrozine. Background technique [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, which not only increases production costs, but also kills a large number of natural enemies of pests and pollutes the environment, resulting in Rampant damage from pests. [0003] Rotenone is a compound derived from plant rotenone root and edamame leaves. It has excellent insecticidal activity and is effective against most agricultural pests. The dosage is low and it degrades quickly in the environment without harming natural enemies and other non-target organisms. It is an excellent biopesticide, but its disadvantage is that it is not systemic. [0004] Pymetrozine is a new pyridine heterocyclic ins...
