Bactericide composition and application thereof

Abstract

The invention discloses a bactericide composition. The bactericide composition contains pyrimethanil and berberine, for 1 part of pyrimethanil, the content of the berberine is 0.01-90 parts by weight. The invention further provides application of the bactericide composition in prevention and control of botrytis of cucumbers, tomatoes, strawberries, grapes, rieger begonia, cyclamen, cineraria, phalaenopsis, poinsettia pulcherrima, peony, China aster, camellia, chrysanthemums, begonia, dahlia, geranium and gladiolus. Through the adoption of the technical scheme, the bactericide composition has obviously enhanced prevention and control effect with respect to the pyrimethanil and berberine.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a fungicide composition and its application. Background technique [0002] Botrytis cinerea is a common and difficult to control fungal disease of open field and protected crops. The disease is an infectious disease caused by Botrytis cinerea, and can affect flowers, fruits, leaves, and stems. The fruit is infected with the disease, and the green fruit is severely damaged. Once the disease occurs, the whole fruit will rot, and the edible value of the fresh fruit will be completely lost. [0003] For a long time, the application of chemical pesticides has been an effective means of preventing gray mold. However, due to the continuous use of similar fungicides, the pathogenic bacteria have changed, produced resistance genes, and reproduced offspring, gradually forming resistant groups, resulting in drug resistance problems. The fungicides that have been used for decades to prevent gray ...

AI Technical Summary

Problems solved by technology

[0003] For a long time, the application of chemical pesticides has been an effective means to prevent and control Botrytis cinerea. However, due to the continuous use of similar fungicides, the pathogenic bacteria will change, produce resistance genes, and reproduce offspring, gradually forming resistant groups, resulting in resistance problems. The fungicides that have been used for decades to prevent gray mold, such as carbendazim, thiophanate, procymidone, and difenazol, have all reported drug resistance

[0004] In the past ten years, new fungicides have emerged, such as triazole fungicides, Ditofencarb, pyrrole fungicides, pyrimidine amine fungicides, and pyridinamine fungicides, etc. Fungicides have poor or even no effect on resistant pathogenic bacteria, and it is difficult to meet the current demand for pesticides to prevent Botrytis cinerea
