Blending preparation of chemical pesticide and biological pesticide and application thereof

Abstract

The invention discloses a blending preparation of a chemical pesticide and a biological pesticide and an application thereof. In the blending preparation, the chemical pesticide is dimehypo, and the biological pesticide is one or more of Azadirachtin missible oil, rotenone missible oil, bacillus thuringiensis and Jinggangmycin. The blending preparation of the invention can obviously reduce the dosage of the chemical pesticide, increases the pesticide effect of the pesticides, reduces pesticide residues, lightens environment pollution and can enhance the resistance of rice so as to reach the purposes for increasing the yield of the rice and improving the quality of the rice, and the blending preparation can be mainly used for preventing and treating Cnaphalocrocis medinalis, Chilo suppressalis, tryporyza incertulas or banded sclerotial blight of the rice.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a compound preparation of chemical pesticides and biological pesticides and applications thereof. Background technique [0002] Pest control is an important part of rice cultivation. For a long time, people have been using chemical pesticides to prevent and control rice diseases and insect pests. Although good results have been achieved, with the passage of time, the change of varieties and the enhancement of the resistance of crop diseases and insect pests, the amount of chemical pesticides has gradually increased. The pesticide residues are increasing, the environmental pollution is becoming more and more serious, the ecological balance is seriously damaged, and human health is seriously threatened. Moreover, the occurrence of a large number of diseases and insect pests has also become an important obstacle restricting the stable and high yield of rice. Contents of the invention ...
