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.

Embodiment 1

[0052] Weigh 5% cycloflufen, 30% tridemorph, 4% TERSPERSE 4894 (produced by Huntsman, USA), 1.5% TERSPERSE 2500 (produced by Huntsman, USA), 2% TERSPERSE 2020 (produced by Huntsman, USA) Mai company), 1% magnesium aluminum silicate, 0.2% xanthan gum, 5% ethylene glycol, 0.5% formaldehyde, 0.5% silicone defoamer (trade name: s-29 produced by Nanjing Sixin Applied Chemicals Co., Ltd. ), 2% triphenyl phosphate, and deionized water are added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 35% cycloflufenad·tridemorph suspension.

Embodiment 2

[0054] Weigh 5% cycloflufen, 50% tridemorph, 2% TERSPERSE 2020 (produced by Huntsman, USA), 2% Span-60#, 2% Tween-60#, 1% TERSPERSE 2500 ( Produced by Huntsman, USA), 0.5% white carbon black, 0.3% xanthan gum, 5% ethylene glycol, 0.5% benzoic acid, 0.5% silicone defoamer (trade name: s-29 Nanjing Sixin Applied Chemical product company), 1% epichlorohydrin, and deionized water are added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill to prepare a 55% cycloflufenad tridemorph suspension.

Embodiment 3

[0056] Weigh 20% cycloflufen, 10% tridemorph, 2% TERSPERSE 2020 (produced by Huntsman, USA), 4% Span-60#, 3% Tween-60#, 4% Nongru 2201 #, 3% Nongru 700#, 1% TERSPERSE 2500 (produced by Huntsman, USA), 0.5% white carbon black, 5% propylene glycol, and methyl oleate are added to 100% by weight. The above-mentioned raw materials were mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill to prepare a 30% cycloflufen-tridemorph dispersible oil suspension concentrate.

Abstract

The invention discloses a bactericidal composition containing cycloflufen and tridemorph and its application. The effective active ingredients are composed of the first active ingredient cycloflufen and the second active ingredient tridemorph. The weight ratio of the ingredient to the second active ingredient is 1:15˜5:1. The composition can be formulated into agriculturally acceptable suspensions, dispersible oil suspensions, aqueous emulsions or suspoemulsions. The composition of the present invention is reasonable, the bactericidal effect is good, and its activity and bactericidal effect are not a simple superposition of the activities of each component. Compared with the existing single preparation, it not only has a significant bactericidal effect, but also has a significant synergistic effect. Good for crop safety. The invention has remarkable control effect on crop powdery mildew.

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...
