Embodiment 1

[0044] Weigh 120 grams of metconazole, 240 grams of captan, 50 grams of alkylphenol polyoxyethylene ether phosphate, 50 grams of sodium lignosulfonate, 30 grams of alkylphenol formaldehyde resin polyoxyethylene ether, 2 grams of bentonite , 2 grams of xanthan gum, 50 grams of urea, 1 gram of benzoic acid, 10 grams of hexanol, and deionized water added to 1000 grams 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 36% metconazole-captan suspension was prepared after the thickness was less than 10 μm.

Embodiment 2

[0046] Weigh 240 grams of metconazole, 120 grams of captan, 55 grams of sodium alkyl polyoxyethylene ether sulfonate, 15 grams of alkylphenol formaldehyde resin polyoxyethylene ether, 8 grams of magnesium aluminum silicate, 26 grams of ethylene glycol , 2 grams of benzoic acid, 18 grams of butanol, and deionized water added to 1000 grams 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 After less than 10μm, a 36% metconazole-captan-proxil suspension was prepared.

Embodiment 3

[0048] Weigh 200 grams of metconazole, 150 grams of captan, 45 grams of sodium alkyl polyoxyethylene ether sulfonate, 14 grams of alkylphenol formaldehyde resin polyoxyethylene ether, 6 grams of magnesium aluminum silicate, 28 grams of ethylene glycol , 3 grams of benzoic acid, 16 grams of butanol, and deionized water added to 1000 grams 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 35% Myconazole Captan Suspension Concentrate was prepared after the thickness was less than 10 μm.

Abstract

The invention discloses application of a bactericidal compound containing metconazole to preventing wheat scab.Effective active components are composed of one of a first active component metconazole and a second active component captan, thiram and prochloraz, the weight ratio of the first active component and the second active component is 20:1-1:20, and the sum of the content of the first active component and the content of the second active component accounts for 5-60% of the total weight of the compound.The compound can be prepared into a suspending agent, microemulsion, emulsion in water, dispersible oil suspending agent, wettable powder and water dispersible granules allowed in agriculture.The compound can also be used for preventing other diseases caused by fusarium graminearum beside wheat scab, and has a remarkable prevention effect on the rice bakanae disease.

Description

technical field [0001] The invention relates to the application of a fungicidal composition containing metconazole in the prevention and treatment of wheat scab. The fungicidal composition consists of the first active ingredient metconazole, the second active ingredient captan, thiram and prochloraz A kind of and auxiliary agent composition, belong to the technical field of pesticide application. Background technique [0002] Meconazole, common name in English: metconazole, chemical name: (1RS, 5RS; 1RS, 5SR)-5-(4-chlorophenyl)-2,2-dimethyl-1-(1-hydrogen-l, 2,4-triazole-1-methyl)cyclopentanol. Meconazole is an inhibitor of C-14 demethylase in ergosterol biosynthesis. Although the mechanism of action is the same as other triazole fungicides, the activity spectrum is quite different. Both isomers have bactericidal activity, but the activity of the cis form is higher than that of the trans form. The fungicidal spectrum of metconazole is very broad and its activity is excell...
