Embodiment 1

[0061]Weigh out 10% syringate, 20% flusilazole, 3% TERSPERSE 2700, 3% diffusing agent NNO, 2% pull powder BX, 1% K-12, 1% carboxymethyl cellulose, 3% urea, Diatomaceous earth was added to 100% by weight. The above-mentioned raw materials are prepared by the conventional method of preparing water-dispersible granules, namely mixing, ultra-fine jet pulverization, mixing, and granulation to prepare 30% syringostrol-flusilazole water-dispersible granules.

[0062] The formula is used for the prevention and treatment of apple tree leaf spot disease. It is sprayed at 5,000 times dilution with water, and the control effect is 91.1% within 15 days after the treatment. The 20% syringostrobin suspending agent is 2000 times and the 40% flusilazole EC is 4000 times, using the same method, the control effect is 78.5% and 76.4% respectively 15 days after the drug.

Embodiment 2

[0064] Weigh 20% syringylstrobin, 30% flusilazole, 4% calcium lignosulfonate, 3% TERSPERSE 2700, 2% pull powder BX, 2% K-12, 3% white carbon black, light calcium and add to 100% by weight. The above-mentioned raw materials are mixed and air pulverized to obtain a 50% syringylstrobin·flusilazole wettable powder.

[0065] The formula is used for the prevention and treatment of apple spot leaf leaf disease. It is sprayed at 6000 times dilution with water, and the control effect is 89.6% within 14 days after the treatment. The 20% syringastrobin suspending agent is 2000 times and the 40% flusilazole EC is 4000 times, using the same method, the control effect after 14 days is 79.2% and 78.2% respectively.

Embodiment 3

[0067] Weigh out 5% syringate, 35% flusilazole, 5% TERSPERSE 4894, 2% TERSPERSE 2500, 3% TERSPERSE 2020, 0.2% xanthan gum, 5% propylene glycol, 0.5% benzoic acid, 1% epichlorohydrin , 0.5% silicone defoamer, 1% epichlorohydrin and deionized water were added to 100% by weight. The above-mentioned raw materials are mixed, disperse by high-speed shearing for 30 minutes, and then be sanded by a sand mill to obtain a 40% syringylstrobin·flusilazole suspension agent.

[0068] The formula is used for the control of rice blast, the dosage per mu is 10g, and it is diluted and sprayed with 50kg of water, and the control effect is 88.5% 10 days after the treatment. The dosage of 20% syringastrobin suspending agent per mu is 22.5g and the dosage of 40% flusilazole EC is 12g. Using the same method, the control effect of 10 days after the drug is 80.3% and 81.6% respectively.

Abstract

The invention discloses an agricultural bactericidal composition containing coumoxystrobin and flusilazole. A weight ratio of coumoxystrobin to flusilazole is in a range of 1: 30 to 30: 1. The bactericidal composition can be processed to form agriculturally acceptable water dispersible granules, wettable powder, a suspending agent, a dispersible oil suspending agent, missible oil, micron emulsion, a suspending seed-coating agent and poultice. The bactericidal composition has reasonable composition, good bactericidal effects, low use cost, and activity and bactericidal effects different from simple superposition of activities and bactericidal effects of all ingredients. Compared with the existing single preparation, the bactericidal composition has substantial bactericidal effects and substantial synergism, delays resistance generation, produces less preparation residues, does not produce pollution on the crops, has good safety, satisfies pesticide preparation safety requirements, and has substantial effects of preventing and treating apple tree rotten disease, apple alternaria leaf spot, rice blast, rice sheath blight, sigatoka and wheat sharp eyespot.

Description

[0001] The patent application of the present invention is a divisional application with the name of invention and creation: a bactericidal composition containing syringate and triazole fungicides, the application number is 201110205478.4, and the application date is 2011-07-19. technical field [0002] The invention relates to an agricultural bactericidal composition containing syringate and triazole fungicides, belonging to the technical field of compound pesticides. Background technique [0003] Methoxy acrylic fungicide is a new type of fungicide developed in recent years, which is a major milestone in the field of fungicides. Methoxyacrylate fungicides have a unique mechanism of action, which blocks the ATP synthesis of cells by locking the electron transfer between cytochrome b and c1, thereby inhibiting their mitochondrial respiration and exerting a bacteriostatic effect. Effective against strains resistant to 14-demethylase inhibitors, benzamides, dicarboxamides and b...
