Embodiment 1

[0045] Weigh 15% pyraclostrobin, 30% hexaconazole, 3% TERSPERSE 2700, 3% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate), 2% pull-off powder BX (dibutyl naphthalene sulfonate sodium lauryl sulfate), 2% K-12 (sodium lauryl sulfate), 1% carboxymethyl cellulose, 5% urea, and diatomaceous earth are added to 100% by weight. 45% pyraclostrobin-hexaconazole 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 2

[0047] Weigh 10% pyraclostrobin, 70% tebuconazole, 1% TERSPERSE 2700, 1% diffusing agent NNO, 1% pull open powder BX, 1% K-12, 1% carboxymethyl cellulose, diatom Soil is added to 100% by weight. 80% pyraclostrobin-tebuconazole water-dispersible granules were prepared from the above-mentioned raw materials through the conventional method for preparing water-dispersible granules, ie mixing, ultra-micro airflow pulverization, mixing, and granulation.

Embodiment 3

[0049] 20% pyraclostrobin, 20% difenoconazole, 4% TERSPERSE 2700, 2% diffusing agent NNO, 2% pull-off powder BX, 2% K-12, 3% corn starch, 5% ammonium sulfate, Attapulgite is added to 100% by weight. 40% pyraclostrobin·difenoconazole 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 sterilizing composition containing isopyrazam and triazole bactericide and application thereof. Effective active components of the sterilizing composition include a first active component and a second active component, wherein the first active component is isopyrazam; the second active component is one of hexaconazole, tebuconazole, difenoconazole, epoxiconazole, cyproconazole and flutriafol; and the weight ratio of the first active component to the second active component is (1:8)-(8:1), preferably (1:5)-(5:1). The composition can be prepared into agriculturally allowable preparation forms such as water dispersible granules, wettable powder and suspending agents. The invention is reasonable in composition and favorable in sterilizing effect; and the activity and the sterilizing effect of the sterilizing composition are not the simple superposition of activities of all the components. Compared with the existing single preparation, the sterilizing composition has remarkable synergistic action beside remarkable sterilizing effect. In addition, the sterilizing composition disclosed by the invention has favorable crop safety, conforms to safety requirements of pesticide preparations and has remarkable control effect on powdery mildew of crops.

Description

technical field [0001] The invention relates to a fungicidal composition containing pyraclostrobin and triazole fungicides, belonging to the technical field of compound pesticides. Background technique [0002] Pyrazastrobin, English common name isopyrazam, chemical name: 3-(fluoromethyl)-1-methyl-N-[1,2,3,4-tetrahydro-9-isopropyl-1,4 -methylene-5-yl]-pyrazole-4-carboxamide. Pyrafenafil is a mitochondrial respiration inhibitor, which has a strong inhibitory effect on the germination of pathogenic spores, the growth of germination tubes and the formation of adsorbers, and has the effect of inhibiting the growth of mycelia and spore formation on fungi. [0003] The common chemical structure of triazole fungicides is that the main chain contains hydroxyl (ketone), substituted phenyl and 1,2,4-triazole group compounds. These agents are active against pathogenic bacteria belonging to the Ascomycotina, Basidiomycotina and Deuteromycotina subphyla, and their mechanism of action i...
