Embodiment 1
[0072] Weigh 7% benthiazil, 56% azoxystrobin, 3% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, USA), 3% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate), 2% pull open powder BX (sodium dibutyl naphthalene sulfonate), 2% K-12 (sodium lauryl sulfate), 1% carboxymethyl cellulose, 5% 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, namely mixing, ultrafine airflow pulverization, mixing, and granulation to prepare 63% benthiazil-azoxystrobin water-dispersible granules.
Embodiment 2
[0074] Weigh 20% benthiazil, 65% kresoxim-methyl, 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, namely mixing, ultra-micro airflow pulverization, mixing, and granulating steps to prepare 85% benthiazin·Kresstrobin water-dispersible granules.
Embodiment 3
[0076] Weigh 10% benthiazil, 50% phenoxystrobin, 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 producing water-dispersible granules, ie, mixing, ultrafine airflow pulverization, mixing, and granulation steps to produce 60% benthiazil·phenoxyfen water-dispersible granules.

Abstract
The invention discloses a benthiavalicarb isopropyl containing bactericidal composition. An effective active ingredient is composed of a first active ingredient and a second active ingredient, wherein the first active ingredient is benthiavalicarb isopropyl, the second active ingredient is selected from strobilurin fungicide azoxystrobin, kresoxim-methyl, metominostrobin, fluoxastrobin, picoxystrobin or coumoxystrobin, the weight ratio of the first active ingredient to the second active ingredient is (1:10)-(8:1), preferably (1:8)-(5:1). The composition can be prepared into agriculturally allowable water dispersible granules, wettable powder and suspending agent dosage forms. The bactericidal composition disclosed by the invention is reasonable in ingredients, good in bactericidal effect and low in medicine application cost, and the activity and bactericidal effect of the bactericidal composition are not the simple combination of the activities of ingredients, so that compared with the existing single preparations, the bactericidal composition not only has a significant bactericidal effect but also has a significant synergistic effect, is low in medicine application cost and good in safety, has no pollution to crops, and conforms to the safety requirements of pesticide preparations. The bactericidal composition disclosed by the invention has a significant control effect on downy mildew, powdery mildew, rice blast and sheath blight of crops.
Description
technical field [0001] The invention relates to a bactericidal composition containing benthiazil and methoxyacrylate fungicides, the active ingredient is selected from the first active ingredient benthiazil and the second active ingredient selected from methoxyacrylate fungicides Azoxystrobin, kresoxim-methyl, phenoxystrobin, fluoxastrobin, picoxystrobin or syringstrobin belong 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] Methoxyacrylic fungicides are newly developed fungicide varieties in...
