Embodiment 1
[0082] Weigh 10% cyanoxystrobin, 50% kresoxim-methyl, 3% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, USA), 2% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate), 3% pull open powder BX (sodium dibutylnaphthalene sulfonate), 2% K-12 (sodium lauryl sulfate), 3% diatomaceous earth, 5% glucose, and kaolin 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% cyclostrobin·Kresstrobin water-dispersible granules.
Embodiment 2
[0084] Weigh 35% cyclostrobin, 15% pyraclostrobin, 1% TERSPERSE 2700, 1% diffusing agent NNO, 1% pull-off powder BX, 8% white carbon black, 1% K-12, 1% carboxyl Methylcellulose 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, namely mixing, ultrafine airflow pulverization, mixing, and granulation steps to produce 50% cyclostrobin · pyraclostrobin water-dispersible granules.
Embodiment 3
[0086] Weigh 36% cystrostrobin, 14% trifloxystrobin, 4% TERSPERSE 2700, 2% diffusing agent NNO, 2% pull open powder BX, 2% K-12, 3% corn starch, 5% ammonium sulfate, concave-convex Rod clay is 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 granulation to prepare 50% cyprostrobin-trifloxystrobin water-dispersible granules.

Abstract
The invention discloses a sterilization composition containing js399-19. The sterilization composition comprises strobilurin bactericide of which the first active component is js399-19 and the second active component is selected from kresoxim-methyl, pyraclostrobin, trifloxystrobin, orysastrobin, fluoxastrobin, picoxystrobin and metominostrobin, wherein the weight ratio of the first active component to the second active component is 1:10-15:1, preferably 1:5-8:1. The composition can be used for preparing agriculturally permitted water dispersible granules, wettable powder, suspending agent, flowable concentrate for seed coating, seed treatment dispersible powder and seed treatment dispersible granule preparation. The sterilization composition has the advantages of reasonable components, good sterilization effect and low application cost, and the activity and sterilization effects of the composition are not simple superposition of the component activities. Compared with theconventional single preparation, the composition has remarkable sterilization effect, remarkable synergic effect, no pollution to crops and good safety, meets the safety requirement of pesticide preparation, and has remarkable prevention effects on wheat take-all, gibberellic disease, rust disease, pyricularia oryzae and bakanae disease.
Description
technical field [0001] The present invention relates to a bactericidal composition, especially a kind of cyclostrobin as the first active ingredient, selected from kysstrobin, pyraclostrobin, trifloxystrobin, orysastrobin, fluoxastrobin, pyridoxine The methoxyacrylate fungicides of oxystrobin and phenoxystrobin as the second active ingredient belong to the technical field of compound pesticides. Background technique [0002] Cyclostrobin, chemical name: ethyl 2-cyano-3-amino-3-phenylacrylate, belongs to cyanoacrylates, is a new type of fungicide independently created by Jiangsu Pesticide Research Institute Co., Ltd. Cyclostrobin is highly efficient, slightly toxic, low residue, and environmentally friendly. It has protective and therapeutic effects on various plant diseases caused by Fusarium, and can be used to prevent and control wheat scab, cotton wilt, rice Bakanae disease, watermelon wilt, etc. At present, there is only one type of 25% cyanoxystrobin suspension concen...
