Abstract

The invention discloses a sterilization composition containing benzothiostrobin and amino-oligosaccharin. The weight ratio of benzothiostrobin to amino-oligosaccharin in the composition is 1:40 to 40:1, preferably 1:20 to 10:1. The composition has a better synergetic effect on cucumber downy mildew within the formulation range, and the composition is good in safety and worthy of popularization and application in production.

Description

technical field [0001] The invention belongs to the field of pesticide compositions, and in particular relates to a fungicidal composition containing penthiostrobin and amino oligosaccharins and an application thereof. Background technique [0002] Benthiastrobin is a new type of methoxyacrylate fungicide developed by Central China Normal University. It has the advantages of broad bactericidal spectrum, high bactericidal activity, low application amount, and long-lasting effect. It has both therapeutic and protective effects. Not only has good control effect on cucumber downy mildew and powdery mildew, but also has excellent control effect on scab, anthracnose, gray mold, corn leaf spot, rice smut, banana fusarium wilt, banana brown gray spot Inhibitory activity, but long-term use alone can easily make the disease resistant. [0003] Amino oligosaccharins (chitooligosaccharides) refer to oligosaccharides linked by D-glucosamine with β-1.4 glycosidic bonds, which are made by...
