Problems solved by technology

[0006] Regardless of whether it is pyrimorph, trifloxystrobin, or other high-efficiency fungicides, long-term single use will easily cause disease resistance, and lead to problems such as increased dosage, reduced control effect, and shortened duration, which is not conducive to environmental sustainability. develop

Abstract

The invention provides a sterilization composition comprising pyrimorph and trifloxystrobin. The sterilization composition is used for preventing and curing ascomycetae, basidiomycetae, oomycetes and deuteromycetes diseases; the active ingredients of the composition are pyrimorph and trifloxystrobin; the weight ratio of the pyrimorph and trifloxystrobin is (1-50):(1-60). The composition reflects excellent synergism within a certain matching range; compared with a single agent, the sterilizing effect of the composition is improved remarkably; pesticide using dosage and cost are reduced; residue is reduced; adverse effect to environment is relieved.

Description

Technical field [0001] The invention belongs to the technical field of pesticide preparations, and specifically relates to a bactericidal composition containing butyromorph and trifloxystrobin. [0002] technical background [0003] Plant diseases have always been one of the important constraints to high-quality and high-yield crops. It is estimated that the average loss of major global crops accounts for about 10% to 15% of total production, and the annual direct economic losses are as high as hundreds of billions of dollars. Among plant diseases, 70% to 80% are caused by infection by pathogenic fungi. Plant fungal diseases not only directly cause crop yield and quality degradation, but also some pathogenic fungi can secrete a variety of toxins and metabolites harmful to humans and animals during the process of infecting crops, thus posing a great threat to the safety of agricultural products. [0004] The English common name of pyrimorph is: pyrimorph, chemical name: 4-...
