Problems solved by technology

[0005] Practical pesticide use experience shows that single and repeated application of an active compound to plant diseases will lead to rapid selection of plant pathogens, that is to say, it is easy to form resistance
Although syringstrobin is a high-efficiency broad-spectrum agricultural fungicide, as a methoxyacrylate compound, it has a single mechanism of action, and long-term repeated use in field applications will cause resistance to pathogens, resulting in reduced control efficiency and increased use costs.

Embodiment 1

[0026] Weigh 5% syringstrobin, 50% fluphenamide, 3% TERSPERSE 2700, 2% diffusing agent NNO, 3% pull open powder BX, 2% K-12, 3% white carbon black, 5% ammonium sulfate, Diatomaceous earth is added to 100% by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, ie, mixing, ultrafine airflow pulverization, mixing, and granulating steps to prepare 55% syringstrobin-fluphenamide water-dispersible granules.

Embodiment 2

[0028] Weigh 50% syringstrobin, 10% fluphenamide, 3% TERSPERSE 4894, 2% TERSPERSE 2500, 1% TERSPERSE 2425, 0.2% xanthan gum, 3% white carbon black, 5% ethylene glycol, 0.3% Benzoic acid, 0.5% silicone defoamer (trade name: s-29 produced by Nanjing Sixin Applied Chemicals Co., Ltd.) and deionized water were 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 60% syringstrobin-fluphenamide suspension concentrate.

Embodiment 3

[0030] Weigh 20% syringstrobin, 2% fluphenamide, 5% calcium lignosulfonate, 2% pull-off powder BX, 2% K-12, 3% white carbon black, kaolin and add to 100% by weight. The above-mentioned raw materials were mixed and air-jet milled to obtain 22% wettable powder of syringstrobin-fluphenamide.

Abstract

The invention relates to a bactericidal composition containing coumoxystrobin and florfenicol, and provides a bactericidal pesticide composition. The active ingredients of the composition are the coumoxystrobin and the florfenicol. The composition has obvious synergism on the rice sheath blight disease; the usage amount of the active ingredients can be lowered, and the use cost is lowered; the generation of the disease resistance can be postponed; and the bactericidal composition is used for the governance on the resistance.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a mixed bactericidal composition containing syringstrobin and fluphenamide. Background technique [0002] Syringstrobin is a methyl methoxyacrylate compound, English common name: coumoxystrobin, chemical name: (E)-2-(2-((3-butyl-4-methyl-coumarin-7 -yl-oxy)methyl)phenyl)-3-methoxymethyl acrylate. It has protective and therapeutic effects. It is an efficient and broad-spectrum agricultural fungicide. It is effective against plant diseases caused by flagella, combined fungi, ascomycetes, basidiomycetes and half-knowledge fungi, such as rape sclerotinia, apple tree rot, cucumber It has good control effect on downy mildew, rice blast, banana leaf spot, apple leaf spot and so on. [0003] Fluphenamide is a pyrazole amide compound (ZL2013105024737) newly developed by Central China Normal University, which has a certain control effect on rice and wheat sheath blight, cucumber and oth...
