Embodiment 1

[0050] Weigh 5% thiamethoxam, 10% difenoconazole, 3% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, USA), 2% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate) , 3% pull open powder BX (dibutyl naphthalene 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 granulating steps to prepare 15% thiazidemeadone·difenoconazole water-dispersible granules. The formula is used to prevent and treat apple tree spot defoliation, and the spray is diluted with water 5000 times, and the control effect is 92.4% after 15 days of application. 5% thiamethoxam ketone suspension was used at 3000 times and 10% difenoconazole water dispersible granule was used at 2000 times by the same method, and the control effects were 74.5% ...

Embodiment 2

[0052] Weigh 10% thiamethoxam, 20% difenoconazole, 3% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, USA), 3% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate) , 2% pull open powder BX (dibutyl naphthalene sulfonate), 1% K-12 (sodium lauryl sulfate), 1% carboxymethyl cellulose, 3% urea, diatomaceous earth added to 100% parts 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 granulating steps to prepare 30% thiazidemeadone·difenoconazole water-dispersible granules. The formula is used for preventing and treating pear scab, and it is diluted with water 10,000 times and sprayed, and the control effect after 7 days of application is 96.1%. 5% thiamethoxazole suspension was used at 4000 times and 10% difenoconazole water dispersible granule was used at 3000 times by the same method, and the control effects were 7...

Embodiment 3

[0054] Weigh 20% thiamethoxam, 5% difenoconazole, 4% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, USA), 2% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate) , 2% pull open powder BX (dibutyl naphthalene sulfonate), 2% K-12 (sodium lauryl sulfate), 3% corn starch, 5% thiamine, attapulgite added to 100% parts 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 granulating steps to prepare 25% thiamethalin·difenoconazole water-dispersible granules. The formula is used for preventing and treating citrus anthracnose, and the spraying is diluted with water by 8000 times, and the control effect is 93.8% within 15 days after application. 5% thiamethoxazole suspension was used at 3000 times and 10% difenoconazole water dispersible granule was used at 2000 times by the same method, and the control effects were 82.8% ...

Abstract

The invention relates to a bactericidal composition containing benziothiazolinone and difenoconazole based on the weight ratio of 1:80-80:1, preferably 1:10-10:1. The bactericidal composition can be prepared into water dispersible granules, wettable powder, suspension agent, water emulsion, microemulsion and emulisfying oil agent. The bactericidal composition has the advantages of rational components, treatment and protection effects, good bactericidal effect, reduced medication times, low medication cost, obvious synergistic effect rather than simple superposition of activity and bactericidal effect of the components, retarded resistance and good safety on crops, thus meeting the safety requirement for pesticide preparations; and the bactericidal composition has better prevention and treatment effects on alternaria leaf spots, scab, anthracnose, powdery mildew and leaf spots on crops such as vegetable, melon and fruit, fruit trees, flower and cereal.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition composed of thiamethoxam and difenoconazole as effective active ingredients and an application thereof, which belongs to the technical field of compound pesticides. Background technique [0002] Benziothiazolinone (Benziothiazolinone) chemical name: 1,2-benzisothiazolin-3-one, belongs to isothiazole compounds. The compound is a high-efficiency, low-toxicity, broad-spectrum bactericide, which can destroy the nucleus structure of pathogenic bacteria, interfere with the metabolism of pathogenic bacteria cells, make them physiologically disordered, and lead to the death of pathogenic bacteria. The compound has a good control effect on crop diseases caused by bacteria and fungi. The thiothiazide developed and produced by Shaanxi Xidahuate Technology Industrial Co., Ltd. was the first agricultural fungicide to be officially registered as a pesticide by the Minist...
