Embodiment 1
[0028] Weigh 10% syringstrobin, 40% cyprodinil, 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. 50% syringstrobin · cyprodinil water dispersible granules are prepared by the conventional method of preparing water dispersible granules from the above raw materials, ie mixing, ultrafine airflow pulverization, mixing and granulation.
[0029] In this embodiment, the weight ratio of syringstrobin and cyprodinil can be varied from 1:30 to 10:1, and the total weight content of the two is still 50%, forming a new embodiment.
Embodiment 2
[0031] Weigh 2% syringstrobin, 60% cyprodinil, 3% TERSPERSE 2700, 3% diffusing agent NNO, 2% pull open powder BX, 1% K-12, 1% carboxymethylcellulose, 3% urea , Diatomite is added to 100% by weight. 62% syringstrobin · cyprodinil water dispersible granules were prepared by the conventional method of preparing water dispersible granules from the above raw materials, that is, mixing, ultrafine airflow pulverization, mixing and granulation.
[0032] In this embodiment, the weight ratio of syringstrobin and cyprodinil can be varied from 1:30 to 10:1, and the total weight content of the two is still 62%, forming a new embodiment.
Embodiment 3
[0034] Weigh 45% syringstrobin, 45% cyprodinil, 3% TERSPERSE 2700, 1% K-12, 2% ammonium sulfate, diatomaceous earth and add to 100% by weight. 90% syringstrobin · cyprodinil water dispersible granules are prepared by the conventional method of preparing water dispersible granules from the above raw materials, ie mixing, ultra-fine airflow pulverization, mixing and granulation.
[0035] In this embodiment, the weight ratio of syringstrobin and cyprodinil can be varied from 1:30 to 10:1, and the total weight composition of the two is still 90%, forming a new embodiment.

Abstract
The invention discloses an agricultural bactericidal composition containing SYP-3375 and cyprodinil. The agricultural bactericidal composition comprises effective active ingredients SYP-3375 and cyprodinil, wherein the weight ratio of SYP-3375 to cyprodinil is (1:30)-(10:1). The composition can be prepared into agriculturally allowable dosage forms such as a water dispersible granule, a wettable powder and a suspending agent. The agricultural bactericidal composition disclosed by the invention has reasonable components, good bactericidal effect and low chemical cost, and the activity and the bactericidal effect of the agricultural bactericidal composition are not simple addition of the activities of various components; compared with the existing single preparations, the agricultural bactericidal composition has obvious synergy besides obvious bactericidal effect, thus the generation of resistance is retarded; and the agricultural bactericidal composition has little preparation residue, no pollution to crops and good safety, meets the safety requirement of pesticide preparations and has obvious control efficiency on grape, strawberry, vegetable gray mold, Alternaria mali, rice sheath blight and rice blast.
Description
technical field [0001] The invention relates to a fungicidal composition containing syringstrobin and cyprodinil, belonging 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 has protection, treatment, eradication, penetration and systemic activities, and can degrade quickly in plants, soil and water. Although this type of fungicide has a unique mechanism of action, the pathogenic bacteria develop resistance to it very quickly, and the cost of use is high, which...
