Embodiment 1
[0043] Weigh 3% benthiazil, 60% captan, 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 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 63% benthiazil-captan water-dispersible granules.
Embodiment 2
[0045] Weigh 10% benthiazil, 70% captan, 2% TERSPERSE 2700, 1% diffusing agent NNO, 2% pull open powder BX, 2% K-12, 1% carboxymethyl cellulose, 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% benthiazil-captan water-dispersible granules.
Embodiment 3
[0047] Weigh 6% benthiazil, 30% captan, 3% TERSPERSE 2700, 3% diffusing agent NNO, 2% pull open powder BX, 1% K-12, 1% carboxymethyl cellulose, 3% 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 36% benthiazil Captan water-dispersible granules.

Abstract
The invention discloses a bactericidal composition with an effective active ingredient composed of benthiavalicarb isopropyl and captan at weight ratio of (1:20)-(10:1), preferably (1:10)-(5:1). The composition can be compounded to agriculturally allowable water dispersible granule, wettable powder or suspending agent. The composition has the advantages of reasonable component, good bactericidal effect and low pesticide utilization cost, and the activity and sterilizing effect are not the simple superposition of the activity of all components. Compared with a single preparation agent, besides the remarkable sterilizing effect, the composition also has the advantages of remarkable synergistic effect, low pesticide utilization cost, zero contamination for plants and good safety, and meets safety requirements of pesticide preparation agent. The composition also has remarkable prevention and cure effects for false mildew, powdery mildew and anthracnose of the crops.
Description
technical field [0001] The invention relates to a bactericidal composition containing benthiazil and captan, the active ingredient is composed of benthiazil and captan, and belongs 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 erosion. [0003] Captan, English name Captan, chemical name: N-trichloromethylthio-1,2,3,6-tetrahydrophthalimide. Captan is a broad-spectrum low-toxicity fungicide, which mainly protects and has a certain therapeutic effect. It can prevent and control various crop diseases on fruit tr...
