Abstract
The invention provides a sterilization composition containing a naphthenic sulfonamide compound and application of the sterilization composition, and belongs to the technical field of pesticides. Thesterilization composition comprises an active component A and an active component B, the active component A is a naphthenic sulfonamide compound SYQUP-CN-26, the active component B is one of triclopyricarb, boscalid and difenoconazole, and the weight ratio of the active component A to the active component B is 1: 4 to 4: 1. The sterilization composition is applied to prevention and treatment of gray mold of crops, and when the weight ratio of the active component A to the active component B is 1: 1, the prevention and treatment effect on gray mold is the best. After the active component A andthe active component B are compounded, the bactericidal composition has obvious synergistic and lasting effects, increases the yield and prevents drug resistance. The bactericidal composition has a good effect of preventing and treating gray mold of crops.
Description
technical field [0001] The invention relates to the technical field of pesticides, in particular to a bactericidal composition containing cycloalkylsulfonamide compounds and its application. Background technique [0002] Phytopathogenic fungi are widely distributed, causing huge economic losses worldwide, and seriously threatening food production and safety (Gurr et al.2011). Botrytis cinerea is one of the top ten fungal diseases that harm various crops. Botrytis cinerea can infect almost any part of a plant, including fruits, flowers, roots, stems, and leaves, reducing crop yield and quality. Its mode of transmission is mainly airborne, and vegetative reproduction is an important way of life. It can kill the host by producing toxins, reactive oxygen species and inducing the burst of plantreactive oxygen species (Dean et al.2012; Escobar- et al. 2019; Choquer et al. 2007). According to reports, botrytis cinerea can cause serious losses before and after harvesting of crop...
