Problems solved by technology

[0007] After searching, the applicant found that there is no bibliographical report on the mixed control of downy mildew and blight of pyrimidine tetrazole and copper nonylcopper, benthiazil, catastamil, and hymexazol. It was found that the compounding of tetrazole pyrimide with different mechanisms of action and one of copper nonyl, benthiazil, catastilil, and hymexazol has unexpected effects, not only significant synergistic effect, but also Significantly improve the control effect of downy mildew and blight on crops, reduce the dosage of pesticides, reduce the cost of control, and ensure the safety of crops

Embodiment 1

[0071]Weigh 20% tetrazole pyrimide, 25% nonyl copper, 4% alkylnaphthalene formaldehyde condensate sodium sulfonate, 5% alkylnaphthalene sulfonate formaldehyde condensate, 5% alkylnaphthalene sulfonate, kaolin Add up to 100% by weight. The above-mentioned raw materials are mixed, pulverized by ultra-fine airflow, and mixed to prepare 45% tetrazole pyrimidine·nonylcopper wettable powder.

Embodiment 2

[0073] Weigh 25% pyrimidine tetrazole, 10% catastil, 6% alkylphenol polyoxyethylene ether phosphate, 4% alkylnaphthalene sulfonate formaldehyde condensate, 4% sodium lauryl sulfate, White carbon black is added up to 100% by weight. The above-mentioned raw materials are mixed, pulverized by ultra-fine airflow, and mixed to prepare 35% tetrazole pyrimidine · catastil wettable powder.

Embodiment 3

[0075] Weigh 10% tetrazole pyridine, 15% benthiazil, 8% polycarboxylate T36, 4% sodium lignosulfonate, 4% pull-off powder BX (sodium dibutylnaphthalene sulfonate), 2 %K-12 (sodium lauryl sulfate), 1% polyethylene glycol, 2% starch, light calcium 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 25% tetrazole pyridine·benthiopyrad water-dispersible granules.

Abstract

A sterilization composition containing picarbutrazox and an amide type sterilizing agent and applications thereof are disclosed. Effective active components include a first active component that is the picarbutrazox and a second active component that is one of cuppricnonylphenolsulfonate, benthiavalicarb-isopropyl, valifenalate and hymexazol. The weight ratio of the first active component to the second active component is 1:80-60:1, preferably 1:60-40:1. The composition can be prepared into agriculturally acceptable dosage forms including wettable powder, water dispersible granules, suspensions, suspoemulsions, emulsions in water, microemulsions, micro-capsule suspensions, micro-capsule suspension-suspension agents, dispersible oil suspensions, and dry type suspensions. The composition has reasonable components and good sterilizing effects. Activity and sterilization effects of the composition are not simple sums of those of each component. Compared with single preparations at present, the composition has significant sterilizing effects and significant synergistic effects and is high in safety to crops. The composition has significant control effects on crop downy mildew and epidemic disease.

Description

technical field [0001] The invention relates to a bactericidal composition, which is composed of the first active component pyrimidine tetrazole, the second active component copper nonyl, benthiazil, catastil, hymexazol and an auxiliary agent, belonging to The field of compound pesticide technology. Background technique [0002] Pyramide tetrazole, English name picarbutrazox, is a carbamate fungicide developed by Japan Soda Corporation. At present, the mechanism of action of pyrimidine tetrazole is not clear, and the International Fungicide Resistance Committee (FRAC) classifies it as an independent U17 category. Pyridine tetrazole at a dose of 50ppm has a significant effect on diseases caused by downy mildew, blight and Pythium, focusing on prevention and protection, and has cross-layer systemic and certain therapeutic activity. [0003] Cuppricnonylphenolsulfonate, English name cuppricnonylphenolsulfonate, cupricnonylphenolsulfonate is a highly permeable organic copper f...
