Abstract

The invention provides a pesticide composition. The pesticide composition comprises dufulin and a dithiocarbamate bactericide, wherein the dithiocarbamate bactericide is one or more selected from propineb, metiram, mancozeb, thiram, zineb and ziram; the weight ratio of dufulin to the dithiocarbamate bactericide is (5:1)-(1:100). The invention also provides a bactericide containing the pesticide composition, wherein the pesticide composition takes up 0.1-90% of the total weight of the bactericide. The pesticide composition and the bactericide provided by the invention show an obvious synergistic effect relative to a single dosage, improve the preventive and treating effects, are suitable for preventing and treating various viral diseases and most fungal diseases, and are an ecological pesticide with relatively high safety and extremely low toxicity.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a pesticide composition containing toxic fluorophosphorus and dithiocarbamate fungicides and a fungicide thereof. Background technique [0002] Dithiocarbamate fungicides are well-known and disclosed pesticide varieties in the art. It is an organosulfur fungicide derived from dithiocarbamic acid, which can prevent and treat various fungal plant diseases, and is not easy to induce The drug resistance of pathogenic microorganisms is widely used in the world. However, due to the long service life of this type of fungicide, the resistance of pathogenic bacteria to this type of fungicide is strengthened, and the control effect of preventing and controlling crop diseases decreases, which cannot meet the control requirements of farmers. [0003] And hexafluorophos is a new generation of plant anti-virus product introduced by the inventor from Guizhou University (Patent No. ZL2005100...
