Embodiment 1
[0052] Weigh 28% oxaflufen, 14% fluopyram, 4% Morwet D-425 (sodium salt of alkylnaphthalenesulfonic acid condensation polymer, produced by AkzoNobel), 3% diffusing agent NNO (alkylnaphthalenesulfonate 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. The above raw materials are prepared through the conventional method for preparing water-dispersible granules, ie mixing, ultra-micro airflow pulverization, mixing, and granulation to prepare 42% oxaflufen-fluopyram water-dispersible granules.
Embodiment 2
[0054] Weigh 55% oxaflufen, 35% fluopyram, 1% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, USA), 1% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate) , 1% pull open powder BX (sodium dibutyl naphthalene sulfonate), 1% K-12 (sodium lauryl sulfate), 1% carboxymethyl cellulose, and diatomaceous earth are 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 90% oxaflufen-fluopyram water-dispersible granules.
Embodiment 3
[0056] Weigh 48% oxafefenone, 12% valitecarb, 4% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, USA), 2% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate), 2% pull open powder BX (sodium dibutyl naphthalene sulfonate), 2% K-12 (sodium lauryl sulfate), 3% corn starch, 5% ammonium sulfate, and attapulgite are added to 100% by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, namely mixing, ultrafine airflow pulverization, mixing, and granulating steps to prepare 60% oxafluconone·valamocarb water-dispersible granules.

Abstract
The invention discloses an agricultural bactericidal composition which contains famoxadone and fungicides preventing and treating oomycetes. The bactericidal composition comprises an effective active ingredient composed of first active ingredient famoxadone and second active ingredient fungicides preventing and treating oomycetes, selected from one of fluopicolide and iprovalicarb; and the weight ratio of the first active ingredient to the second active ingredient is 1:5-15:1. The composition can be prepared into a water dispersible granule, wettable powder, a suspending agent and a flowable concentrate for seed coating allowed in agriculture. The bactericidal composition has the beneficial effects that components are reasonable, the sterilizing effect is good, the pesticide use cost is low, and the activity and the sterilizing effect of the bactericidal composition are not simply superposed by the activities of all the components; and compared with the present single preparation, the bactericidal composition not only has remarkable sterilizing effect, but also has remarkable synergistic effect, has no pollution to crops, is good in safety and conforms to the safety requirements of pesticide preparations. The bactericidal composition has remarkable prevention and treatment effect on crop downy mildew, epidemic diseases, cataplexy diseases and downy blight.
Description
technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition compounded by oxaflucone, fluopicolide or varefencarb, and belongs to the technical field of compound pesticides. Background technique [0002] Famoxadone English common name is famoxadone, molecular formula C 22 h 18 N 2 o 4 , chemical name: 3-anilino-5-methyl-5-(4-phenoxyphenyl)-1,3-oxazoline-2,4-dione. It is a new type of high-efficiency and broad-spectrum fungicide. Its mechanism of action is a mitochondrial electron transfer inhibitor. It has protection, treatment, eradication, penetration, and systemic activities. It has no cross-resistance with phenylamide fungicides and is suitable for crops such as wheat. , barley, peas, sugar beets, rapeseed, grapes, potatoes, melons, peppers, tomatoes, fruit trees, etc. It is mainly used to control important diseases in Ascomycetes, Basidiomycetes, and Oomycetes, such as powdery mildew, rust, glume blight, n...
