Embodiment 1

[0037] Take by weighing 10 grams of metconazole, 20 grams of tebuconazole, 45 grams of TERSPERSE 4894 (produced by Huntsman, U.S.), 20 grams of polycarboxylate TERSPERSE 2700 (produced by Huntsman, U.S.), 15 grams of TERSPERSE 2500 (produced by Huntsman, U.S. Produced by Huntsman), 30 grams of polyvinylpyrrolidone, 5 grams of xanthan gum, 40 grams of ethylene glycol, 3 grams of benzoic acid, 5 grams of silicone defoamer (trade name: s-29 Nanjing Sixin Applied Chemicals Company produces), deionized water is added to 1000 gram parts by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 3% metconazole-tebuconazole suspension seed coating.

Embodiment 2

[0039] Weigh 25 grams of metconazole, 15 grams of tebuconazole, 40 grams of TERSPERSE 4894 (produced by Huntsman, USA), 30 grams of TERSPERSE 2020 (produced by Huntsman, USA), 25 grams of phenylethylphenol polyoxyethylene Ether phosphate, 20 grams of hydroxypropyl methylcellulose, 8 grams of bentonite, 30 grams of propylene glycol, 6 grams of sodium benzoate, 5 grams of silicone defoamer (trade name: s-29 produced by Nanjing Sixin Applied Chemicals Co., Ltd.) , deionized water is added to 1000 grams by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 4% metconazole-tebuconazole suspension seed coating.

Embodiment 3

[0041] Weigh 20 grams of metconazole, 10 grams of tebuconazole, 40 grams of alkylphenol polyoxyethylene ether phosphate, 30 grams of phenylethylphenol polyoxyethylene ether phosphate, 50 grams of polycarboxylate sodium, 30 grams Hydroxypropyl methylcellulose, diatomaceous earth is supplemented to 1000 gram parts by weight. The above raw materials are mixed and crushed by air flow to prepare 3% metconazole tebuconazole dry seed dressing.

Abstract

The invention discloses application of a metconazole-containing sterilizing composition in preventing and controlling bakanae disease. Active ingredients are composed of a first active ingredient, metconazole and a second active ingredient, tebuconazole according to a weight ratio of 40:1-1:40, and a content sum of the first active ingredient and the second active ingredient is 1-60% of total weight of the composition. The composition can be prepared into agricultural-allowable suspended seed coatings, dry seed dressing agents, seed treatment microcapsule suspending agents, seed treatment suspending agents, wettable powder, water-dispersible granules, dispersible oil suspending agents and suspending agents. The composition has remarkable preventive effect on bakanae disease.

Description

technical field [0001] The invention relates to the application of a fungicidal composition containing metconazole in the prevention and treatment of rice bakanae disease. The fungicidal composition is composed of the first active ingredient metconazole, the second active ingredient tebuconazole and an auxiliary agent, and belongs to the application of pesticides technology field. Background technique [0002] Meconazole, English common name: 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 excellent.
