Bactericidal composition containing valifenalate and procymidone

Abstract

The invention provides a bactericidal composition containing valifenalate and procymidone. According to the bactericidal composition, effective components including the valifenalate and the procymidone are subjected to binary compounding and the balance is auxiliary components. When the mass ratio of the effective components including the valifenalate and the procymidone in a pesticide compositionis (1 to 80) : (80 to 1), preferably (1 to 10) : (10 to 1), the synergistic effect is optimal. In a preparation, the mass percent content of the effective components including the valifenalate and the procymidone is 1 percent to 90 percent of the total weight; preferably, the mass percent content of the effective components is 3 percent to 80 percent when the bactericidal composition is used fortreating tomato gray mold and rape sclerotinia rot; the balance is auxiliary components allowable and acceptable in pesticide; preparations of the pesticide composition comprise wettable powder, waterdispersible granules, a suspending agent, a dispersible oil suspending agent and the like; the pesticide composition is mainly used for preventing and controlling sclerotinia sclerotiorum, gray mold,venturia inaequalis, brown rot and leaf blight of fruit trees, vegetables, flowers and the like.

Description

technical field [0001] The invention belongs to the technical field of pesticide compounding, and in particular relates to a bactericidal composition, in particular to a bactericidal composition containing valerosamine and procymidone. Background technique [0002] Procymidone is a protective and therapeutic fungicide with a certain systemic effect, and is currently the backbone of cyclophthalimide agricultural fungicides. It has high efficiency, low toxicity, safe use, short half-life in soil, and no adverse effects on the environment and ecology. It mainly acts on the cell membrane to inhibit the synthesis of triglycerides in the bacteria, hinder the normal synthesis of the cell wall at the top of the hyphae and inhibit the development of the mycelium. It has the effect of sucking from the leaves and roots, so it has good resistance to rain erosion, and can control diseases that are not directly sprayed on the part of the agent. It is also effective for pathogens that hav...

Problems solved by technology

Although there are many researches on the control methods of Botrytis cinerea, as the antigen of Botrytis cinerea has not been found so far, it is difficult to implement disease-resistant breeding, so at present China mainly relies on chemical methods to control Botrytis cinerea

[0006] However, in practical applications, long-term single application of an active compound to control diseases will lead to the development of disease resistance, resulting in a decrease in the control effect of the compound, or even a complete loss of control effect.
