Problems solved by technology

However, not any two pesticide single agents can be compounded and used in this way, because there are also problems in this compounding. For example, although some active ingredients have no problem in their respective use, after compounding and using, they will produce The intermediate products may have adverse chemical reactions and cause environmental pollution problems
At present, there is no report on the compound combination of pentothiastrobin and difenoconazole

Abstract

The invention relates to a sterilization compound containing benzothiostrobin and difenoconazole. The sterilization compound comprises active ingredients and pesticide preparation auxiliary components, wherein the active ingredients comprise benzothiostrobin and difenoconazole. The benzothiostrobin and the difenoconazole in the sterilization compound provided by the invention belong to two bactericides with different mechanisms, and can be compounded within a certain proportion range to generate a remarkable synergistic role. The sterilization compound is remarkable in prevention and control effect, is safe to crops without damage risk, is reduced in acute toxicity to mammals, and is improved in safety.

Description

technical field [0001] The invention belongs to the technical field of pesticide application, and relates to a fungicidal composition containing benzathystrobin and difenoconazole, and also relates to the application of the fungicidal composition. Background technique [0002] Penthiastrobin is a methoxyacrylate fungicide, and its mechanism of action is to inhibit mitochondrial respiration. It is an environmentally friendly fungicide with high efficiency, broad spectrum and low toxicity. In addition, benzothiastrobin has a good control effect on powdery mildew, stripe rust, downy mildew, leaf spot and rice blast on fruit trees, vegetables and cereal crops due to its good protection, treatment, eradication and bactericidal effects. [0003] Difenoconazole is a triazole fungicide. It inhibits the synthesis of fungal ergosterol and hinders the formation of cell walls. It is a C-14 demethylase inhibitor in sterol biosynthesis. It is safe and effective for crops at recommended do...
