Embodiment 1

[0055] Weigh 12% pyraclostrobin, 36% Cyazofamid, 4% Morwet D-425 (sodium salt of alkylnaphthalenesulfonic acid condensation polymer, produced by Akzo Nobel), 3% diffusing agent NNO (alkylnaphthalenesulfonic acid salt formaldehyde condensate), 2% pull open powder BX (sodium dibutylnaphthalene sulfonate), 2% K-12 (sodium lauryl sulfate), 3% corn starch, 5% sucrose, kaolin to 100 % parts by weight. 48% pyraclostrobin·cyazofamida water-dispersible granules were prepared by the above-mentioned raw materials through the conventional method for preparing water-dispersible granules, ie mixing, ultra-micro airflow pulverization, mixing, and granulation.

Embodiment 2

[0057] Weigh 20% pyraclostrobin, 20% Cyazofamid, 4% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, USA), 2% diffusing agent NNO, 2% pull-off powder BX, 2% K -12. 3% cornstarch, 5% ammonium sulfate, and attapulgite are added to 100% by weight. 40% pyraclostrobin·cyazofamida 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 15% pyraclostrobin, 75% aluminum triethylphosphonate, 1% TERSPERSE 2700, 1% diffusing agent NNO, 1% pull-off powder BX, 1% K-12, 1% carboxymethylcellulose, Diatomaceous earth is added to 100% by weight. 90% pyraclostrobin·aluminum triethronate 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 pyraclostrobin, which comprises a first active ingredient pyraclostrobin and a second active ingredient cyazofamid or phosethyl-aluminium, wherein the weight ratio of the first active ingredient to the second active ingredient is 1:15-10:1. The bactericidal composition can be prepared into water-dispersible granules, wettable powder and a suspending agent which are permitted in the agriculture. The bactericidal composition is reasonable in ingredient, good in bactericidal effect and low in drug cost, and the activity and the bactericidal effect are not formed by the activities of the ingredient simply. Compared with an existing single preparation, the bactericidal composition has the remarkable synergistic effect and good safety to crops besides the remarkable bactericidal effect, meets the safety requirements of pesticide preparations, and has remarkable preventive and treatment effect on downy mildew, epidemic diseases and leaf spot diseases of the crops.

Description

technical field [0001] The present invention relates to a bactericidal composition containing pyraclostrobin, in particular to a bactericidal composition containing pyraclostrobin as the first active ingredient, and cyafamid or aluminum triethronate as the second active ingredient. It belongs to the technical field of compound pesticides. Background technique [0002] Pyraclostrobin, also known as pyraclostrobin, English common name: Pyraclostrobin, chemical name: N-{2-[1-(4-chlorophenyl)-1H-pyrazol-3-yloxymethyl] Phenyl}(N-methoxy)carbamate. Pyraclostrobin is a methoxyacrylate fungicide, which mainly acts on the cytochrome bel complex in the mitochondrial respiratory chain of fungi, preventing electron transfer and thus inhibiting fungal growth. It can prevent all types of fungal pathogens, has a wide bactericidal spectrum, and is effective for various diseases of various crops, including wheat, grapes, fruit trees, and vegetables. It is mainly used to prevent and control...
