Embodiment 1

[0015] Weigh 0.5% cyclostrobin, 1% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, USA), 1% TERSPERSE 2500 (produced by Huntsman, USA), 3% TERSPERSE 4894 (produced by Huntsman, USA) produced), 2.0% polyvinylpyrrolidone, 0.2% xanthan gum, 5% ethylene glycol, 0.3% benzoic acid, 0.5% silicone defoamer (trade name: s-29 produced by Nanjing Sixin Applied Chemicals Company) to Ionized water was 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 0.5% cyclostrobin suspension seed coating agent.

Embodiment 2

[0017] Weigh 15% cystrobin, 3% TERSPERSE 4894, 2% TERSPERSE 2500, 1% TERSPERSE 2020 (produced by Huntsman, USA), 3.0% hydroxypropyl methylcellulose, 0.5% bentonite, 5% ethylene glycol , 0.3% sodium benzoate, 0.5% organic silicon defoamer deionized water 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 15% cyclostrobin suspension seed coating.

Embodiment 3

[0019] Weigh 30% cyclostrobin, 3% TERSPERSE 4894, 1% alkylphenol polyoxyethylene ether formaldehyde condensate sulfate, 1% diffusing agent NNO (alkylnaphthalene sulfonate formaldehyde condensate), 2.0% poly Vinyl acetate, 0.2% xanthan gum, 5% propylene glycol, 0.3% benzoic acid, 0.5% silicone defoamer 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 30% cyclostrobin suspension seed coating.

Abstract

The invention discloses an application of JS399-19 (2-cyano-3-amino-3-phenylacrylic acetate) in preventing and controlling wheat take-all. The JS399-19 can be prepared into agriculturally allowable suspending seed coating agents, seed treatment dispersible powder, and seed treatment dispersible granules. The JS399-19 has effects of controlling and protecting the wheat take-all, good sterilizing effect, low use cost, and good crop safety, and can slow down the production of resistance and meet the safety requirement of the pesticide preparation. The indoor toxicity EC50 (50% effective concentration) of the JS399-19 to the wheat take-all bacteria is 3.62 mg / L, and the JS399-19 has higher activity, the prevention and control effect to the wheat take-all is 82.20%-94.15%, the production of the wheat is increased by 75.2%-83.3%, and the JS399-19 is superior to the like product abroad.

Description

technical field [0001] The invention relates to the application of cyprostrobin in preventing and treating wheat take-all, and belongs to the technical field of pesticides. Background technique [0002] Cyclostrobin, chemical name: ethyl 2-cyano-3-phenyl-3-aminoacrylate, belongs to cyanoacrylates, is a new type of fungicide independently created by Jiangsu Pesticide Research Institute Co., Ltd. Cyclostrobin is highly efficient, slightly toxic, low residue, and environmentally friendly. It has protective and therapeutic effects on various plant diseases caused by Fusarium, and can be used to prevent and control wheat scab, cotton wilt, banana Panama disease, rice bakanae disease, watermelon wilt, etc. At present, there is only one type of 25% cyanoxystrobin suspension concentrate on the market, and the control objects registered in the Ministry of Agriculture are wheat head blight and rice bakanae disease. [0003] Wheat take-all is an important root disease caused by wheat...
