Bactericidal composition containing cyflufenamid and tridemorph

Abstract

The invention discloses a bactericidal composition containing cyflufenamid and tridemorph and an application of the bactericidal composition. The active ingredients of the bactericidal composition comprise a first active ingredient cyflufenamid and a second active ingredient tridemorph, wherein the weight ratio of the first active ingredient to the second active ingredient is (1 to 15)-(5 to 1). The composition can be prepared into agriculturally allowable dosage forms such as suspending agents, dispersible oil suspending agents, emulsion in water or suspension emulsion. The bactericidal composition has the advantages of reasonable ingredients and good bactericidal effects; the activity and bactericidal effects of the bactericidal composition are not simple superposition of the activities of the ingredients; compared with existing single preparations, the bactericidal composition has obvious synergistic effects besides obvious bactericidal effects, has good safety to crops and has obvious control effects on powdery mildew of crops.

Description

technical field [0001] The invention relates to a bactericidal composition, which is composed of a first active ingredient cycloflufen, a second active ingredient tridemorph and an auxiliary agent, and belongs to the technical field of compound pesticides. Background technique [0002] Cyflufenamide, English common name cyflufenamid, chemical name: (Z)-N-[α-(cyclopropylmethoxyimino)-2,3-difluoro-6-(trifluoromethyl)benzyl]- 2-Phenylacetamide. Cyflufenamide is a phenylacetamide fungicide developed by Nippon Soda Co., Ltd., which has excellent preventive effect and certain therapeutic activity. characteristics, but poor systemic absorption. It is mainly used to control powdery mildew on vegetables, fruit trees, and various grains. [0003] Tridemorpholine, English common name Tridemorph, chemical name: 2,6-dimethyl-4-tridecylmorpholine. Tridemorph is a broad-spectrum systemic fungicide with protective and therapeutic effects, which can be absorbed by the roots, stems and le...

AI Technical Summary

Problems solved by technology

[0004] Powdery mildew is an important disease that commonly occurs on crops such as wheat, melons, beans, strawberries, flowers, grapes, and apples, and often causes great losses. Currently, tebuconazole, myclobutanil, triadimefon, and fluorine are commonly used to prevent and control crop powdery mildew. Silazole, pyrimethrin, kresoxim-methyl, thiophanate-methyl, carbendazim and other pesticides have been used for many years, and the bacteria have developed resistance to these pesticides, and triazoles are not safe for dicotyledonous crops and are used improperly Pesticide accidents are often caused, and it is urgent to invent a pesticide with good control effect on crop powdery mildew and high safety to crops

There is a risk of resistance after cycloflufen is on the market. Tridemorph is registered for the prevention and treatment of rubber red root disease. At present, there is no literature report on the mixture of cycloflufen and tridemorph to control crop powdery mildew. The inventor passed the test It is found that the combination of cycloflufen and tridemorph with different action mechanisms has obvious synergistic effect, can significantly improve the control effect on crop powdery mildew, reduce the dosage of drugs, reduce the cost of control, and have high safety for crops.
