Embodiment 1

[0052] Weigh 3% benthiazil, 60% aluminum triethylphosphonate, 3% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, USA), 2% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate ), 3% pull open powder BX (sodium dibutylnaphthalene sulfonate), 2% K-12 (sodium lauryl sulfate), 3% diatomaceous earth, 5% glucose, and kaolin to 100% by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, ie, mixing, ultra-micro airflow pulverization, mixing, and granulation to prepare 63% benthiazil·aluminum triethylphosphonate water-dispersible granules.

Embodiment 2

[0054] Weigh 10% benthiazil, 70% cymoxanil, 2% TERSPERSE 2700, 1% diffusing agent NNO, 2% pull open powder BX, 2% K-12, 1% carboxymethylcellulose, 2% urea , Diatomite is 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 80% benthiazan·cymoxanil water-dispersible granules.

Embodiment 3

[0056] Weigh 10% benthiazil, 50% dimethomorph, 3% TERSPERSE 2700, 3% diffusing agent NNO, 2% pull open powder BX, 1% K-12, 1% carboxymethyl cellulose, 3% Urea and diatomaceous earth are added to 100% by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, namely mixing, ultra-micro airflow pulverization, mixing, and granulation to prepare 60% benthiazil·dimethomorph water-dispersible granules.

Abstract

The invention discloses a sterilization composition containing benthiavalicarb isopropyl and bactericide for preventing and treating oomycetes, comprising a first active ingredient benthiavalicarb isopropyl and a second active ingredient which is one selected from bactericides for preventing and treating oomycetes, such as phosethyl-aluminium, cymoxanil, dimethomorph, benalaxyl, cyazofamid, fluopicolide, iprovalicarb and oxadixyl, wherein weight ratio of the first active ingredient to the second active ingredient is 0.05-5. The sterilization composition disclosed by the invention can be prepared into agriculturally allowable water dispersible granules, wettable powder or suspending agent. The sterilization composition disclosed by the invention is reasonable in components, good in sterilization effect and low in medication cost, and activity and sterilization effect of the sterilization composition are not simple addition of activities of each component; and compared with the existing single preparation, the sterilization composition disclosed by the invention has obvious synergistic effect besides obvious sterilization effect, is low in the medication cost, produces no pollution to crops, has good safety and accords with safety requirements of pesticide preparation, so that the sterilization composition disclosed by the invention has obvious control effect to downy mildew and epidemic disease of the crop.

Description

technical field [0001] The present invention relates to a bactericidal composition containing benthiazil and fungicides for preventing and controlling oomycetes. The first active ingredient, benthiazil, and the second active ingredient are selected from triethylphosphine of fungicides for preventing and controlling oomycetes. It is a composition of aluminum cyanate, cymoxanil, dimethomorph, benalaxyl, cyazofamid, fluopicolide, valemocarb and oxaxyl, belonging to the technical field of compound pesticides. Background technique [0002] Benthiazil, English common name: benthiavalicarb-isopropyl, chemical name: [[(6-fluorobenzothiazol-2-yl)-ethylcarbamoyl]-2-methylpropyl]carbamate isopropyl , is a new type of fungicide jointly developed by Combination Chemical Industry Company and Ihara Company. Benthiopyram has good activity against oomycete fungal diseases, has strong preventive, therapeutic and osmotic activities, and has good long-lasting effect and resistance to rain eros...
