Embodiment 1
[0055] Weigh 10% syringstrobin, 60% thiophanate-methyl, 3% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, USA), 2% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate) , 3% pull open powder BX (sodium dibutyl naphthalene sulfonate), 2% K-12 (sodium lauryl sulfate), 3% diatomaceous earth, 5% glucose, and kaolin are added to 100% by weight. 70% syringstrobin · thiophanate-methyl water-dispersible granules were prepared by the conventional method of preparing water-dispersible granules from the above-mentioned raw materials, ie, mixing, ultrafine airflow pulverization, mixing, and granulation.
Embodiment 2
[0057] Weigh 1.5% syringstrobin, 75% thiophanate-methyl, 3% TERSPERSE 2700, 3% diffusing agent NNO, 2% pull open powder BX, 1% K-12, 1% carboxymethylcellulose, 3% Urea and diatomaceous earth are added to 100% by weight. 76.5% syringstrobin · thiophanate-methyl water-dispersible granules were prepared by the above-mentioned raw materials through the conventional method for preparing water-dispersible granules, ie mixing, ultrafine airflow pulverization, mixing, and granulation.
Embodiment 3
[0059] Weigh 8% syringstrobin, 40% thiophanate-methyl, 4% TERSPERSE 2700, 2% diffusing agent NNO, 2% opening powder BX, 2% K-12, 3% corn starch, 5% ammonium sulfate, Attapulgite is added to 100% by weight. 48% syringstrobin · thiophanate-methyl water-dispersible granules were prepared by the above-mentioned raw materials through the conventional method for preparing water-dispersible granules, ie mixing, ultrafine airflow pulverization, mixing, and granulation.

Abstract
The invention discloses a bactericidal composition containing coumoxystrobin and benzimidazole bactericide. The bactericidal composition comprises the coumoxystrobin serving as an active ingredient and the benzimidazole bactericide selected from thiophanatemethyl, carbendazol or benomyl; and the weight ratio of the coumoxystrobin to the benzimidazole bactericide is 1:1-1:50. The composition can be prepared into agriculturally allowable water dispersible granules, wettable powder or suspension. The composition has reasonable components, good bactericidal effect and low application cost, and the activity and the bactericidal effect of the composition are not simply superposed activity and bactericidal effect of the components; compared with the conventional single preparation, the composition has the advantages of remarkable bactericidal effect, remarkable synergy, retarded resistance, low preparation residue, no pollution to crops, good safety and accordance with the safety requirement of the pesticide preparation; and the composition has remarkable effect of preventing and controlling apple ring rot, anthracnose, rot, rice sheath blight, rice blast and wheat scab.
Description
technical field [0001] The present invention relates to a bactericidal composition containing syringstrobin, in particular to a benzimidazole bactericidal composition containing syringstrobin as the first active ingredient selected from thiophanate-methyl, carbendazim and benomyl The invention discloses a bactericidal composition and application thereof, which are used as the second active ingredient, and belong to the technical field of compound pesticides. Background technique [0002] Methoxyacrylic fungicides are newly developed fungicide varieties in recent years and are a major milestone in the field of fungicides. Methoxyacrylate fungicides have a unique mechanism of action, which prevents ATP synthesis in cells by locking the electron transfer between cytochrome b and c1, thereby inhibiting mitochondrial respiration and exerting antibacterial effects. Effective against strains resistant to 14-demethylase inhibitors, benzamides, dicarboxamides and benzimidazoles. It...
