Embodiment 1

[0051] Weigh 20% cyproconazole, 40% tricyclazole, 3% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, U.S.), 2% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate), 3% pull-off powder BX (sodium dibutylnaphthalene sulfonate), 2% K-12 (sodium lauryl sulfate), 3% diatomaceous earth, 5% glucose, and kaolin are added to 100% by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, ie, mixing, ultrafine airflow pulverization, mixing, and granulation to prepare 60% cyproconazole·tricyclazole water-dispersible granules. The formula is used for preventing and treating rice blast, and the spraying is diluted with water by 3500 times, and the control effect is 95.4% 15 days after application. 10% Cyproconazole Suspension Concentrate 1000 times and 75% Tricyclazole WP 2000 times, using the same method, the control effect of 14 days after the drug is 73.2% and 85.6% respectively.

Embodiment 2

[0053] Weigh 10% cyproconazole, 50% tricyclazole, 3% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, U.S.), 3% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate), 2% pull open powder BX (sodium dibutyl naphthalene sulfonate), 1% K-12 (sodium lauryl sulfate), 1% carboxymethyl cellulose, 3% urea, diatomaceous earth added to 100% by weight share. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, ie, mixing, ultrafine airflow pulverization, mixing, and granulation to prepare 60% cyproconazole·tricyclazole water-dispersible granules. The formula is used for preventing and treating rice blast, and the spraying is diluted with water by 3000 times, and the control effect is 96.1% 14 days after application. 10% Cyproconazole Suspension Concentrate 1000 times and 75% Tricyclazole WP 2000 times, using the same method, the control effect of 14 days after the drug is 68.5% and 84.8% respec...

Embodiment 3

[0055] Weigh 5% cyproconazole, 75% tricyclazole, 4% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, U.S.), 2% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate), 2% pull-off powder BX (sodium dibutylnaphthalene sulfonate), 2% K-12 (sodium lauryl sulfate), 3% corn starch, 5% ammonium sulfate, and attapulgite are added to 100% by weight. 80% cyproconazole·tricyclazole water-dispersible granules are prepared by the conventional method for preparing water-dispersible granules from the above-mentioned raw materials, ie, mixing, ultrafine airflow pulverization, mixing, and granulation. The formula is used to prevent and treat rice blast, and the spray is diluted with water 3000 times, and the control effect is 93.6% 14 days after application. 10% Cyproconazole Suspension Concentrate 1000 times and 75% Tricyclazole WP 2000 times, using the same method, the control effect of 14 days after the drug is 72.8% and 84.2% respectively.

Abstract

The invention discloses a bactericidal composition containing cyproconazole, wherein the weight ratio of cyproconazole to tricyclazole / isoprothiolane is 5:1-1:20, and the composition can be prepared into water dispersible granules, wettable powder, suspension concentrates, dispersible oil miscible flowable concentrates, micro-emulsion or emulsion concentrates. The bactericidal composition can be used for preventing and treating rice blast, sheath blight and false smut and has reasonable components, both the prevention and the treatment roles, good bactericidal effect, and expanded prevention and treatment spectrum; one-time application can prevent and treat three diseases of rice blast, sheath blight and false smut, thereby reducing the application times and reducing the application cost;furthermore, the activity and the bactericidal effect of the bactericidal composition to the rice blast are not the simple overlapping of the activities of all the components, and all the components realize the significant synergy, thereby retarding the production of drug resistance, having good safety to crops and being in line with the safety requirement of pesticide preparations.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition whose active ingredients are composed of cyproconazole, tricyclazole or rice blastin, and belongs to the technical field of compound pesticides. Background technique [0002] Cyproconazole English common name cyproconazole, molecular formula C 15 h 18 ClN 3 O, chemical name 2-(4-chlorophenyl)-3-cyclopropyl-1-(1H-1,2,4-triazol-1-yl)butan-2-ol, belongs to azole fungicides, The mechanism of action is to inhibit the demethylation of sterols. It is used to prevent and treat cereal and coffee rust, cereal, fruit tree and grape powdery mildew, peanut and beet leaf spot, apple scab and peanut white rot. It has preventive and therapeutic effects. Powdery mildews, Rusts, Sporophytes on cereal crops (up to 80g / ha), coffee (20-50g / ha), sugar beets (40-60g / ha), fruit trees and grapes (10g / ha) The genus Coryza, Septoria, Septoria, and Black Star are all effective aga...
