Problems solved by technology

[0004] After searching, the applicant found that there is no literature report on the mixing of metrafenone and flufenapyramide for the prevention and treatment of powdery mildew. Further tests have found that the compounding of metrafenone and flufenapyramide with different mechanisms of action has an unexpected effect. Not only the synergistic effect is significant, but also the control effect on powdery mildew can be significantly improved, the dosage of medicine can be reduced, the cost of control can be reduced, and it is safe for crops.

Embodiment 1

[0056] Weigh 20% metrafenone, 10% flufenapyramide, 5% polycarboxylate, 5% phenethylphenol polyoxyethylene ether phosphate, 4% alkyl sodium sulfate, 0.5% carboxymethyl cellulose , 3% sorbitol, 0.3% formaldehyde, 1% butanol, deionized water added to 100% by weight. The above raw materials are mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to a particle size of D 90 A 30% metrafenone-flufenapyramide suspension was prepared after the thickness was less than 10 μm.

Embodiment 2

[0058] Weigh 5% metrafenone, 25% flufenapyramide, 5% sodium lignosulfonate, 4% sodium naphthalenesulfonate, 6% sodium alkyl sulfate, 0.4% magnesium aluminum silicate, 0.1% bentonite, 4% Propylene glycol, 0.1% sodium benzoate, 1% hexanol, and deionized water are added to 100% by weight. The above raw materials are mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to a particle size of D 90 A 30% metrafenone-flufenapyramide suspension concentrate was prepared after the thickness was less than 10 μm.

Embodiment 3

[0060] Weigh 10% metrafenone, 15% flufenapyramide, 4% sodium alkylnaphthalene formaldehyde condensate sulfonate, 3% phenethylphenol polyoxyethylene ether phosphate, 5% sodium alkyl sulfate, 0.4% Carboxyethyl cellulose, 2% polyethylene glycol, 0.2% potassium sorbate, 2% octanol, and deionized water are added to 100% by weight. The above raw materials are mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to a particle size of D 90 A 25% metrafenone-flufenapyramide suspension concentrate was prepared after the thickness was less than 10 μm.

Abstract

The invention discloses a sterilization composition containing metrafenone and fluxapyroxad and an application of the sterilization composition. The sterilization composition is prepared from the first effective active ingredient metrafenone and the second effective active ingredient fluxapyroxad. The weight ratio of the first active ingredient to the second active ingredient is 1:80 to 80:1, and is preferably 1:40 to 40:1. The composition can be prepared into a suspending agent, microemulsion, emulsion in water, a dispersible oil suspending agent, wettable powder and water dispersible granules which are agriculturally allowed. The sterilization composition is reasonable in component and good in sterilization effect, and the activity and sterilization effect of the sterilization composition are not achieved simply by overlapping the activity of all the components. Compared with an existing single preparation, the remarkable sterilization effect is achieved, besides, the remarkable synergistic effect is achieved, and safety for crops is good. The sterilization composition has the remarkable preventing and controlling effect on crop powdery mildew.

Description

technical field [0001] The invention relates to a bactericidal composition, which is composed of the first active ingredient metrafenone, the second active ingredient flufenapyramide and auxiliary agents, and belongs to the technical field of compound pesticides. Background technique [0002] Metrafenone, the English name is metrafenone, and the chemical name is 3'-bromo-2,3,4,6'-tetramethoxy-2',6-dimethylbenzophenone. The benzophenone fungicides developed by BASF in Germany were first created in 1998 by the American cyanamide company (now owned by BASF). It has been registered in many countries since 2003 and launched in Chile in 2009. It has the functions of protection, treatment, eradication and inhibition of sporulation for various types of powdery mildew. It can strongly inhibit the germination of pathogenic bacteria steamed buns at low mass concentrations. It is different from the mechanism of action of known commercial fungicides. It has been reported that the mecha...
