Problems solved by technology

[0007] After retrieval by the applicant, there is no bibliographic report on the mixing of pyrimidine tetrazole and tricyclazole, rice blastamide, rice blastling, and kasugamycin for the prevention and treatment of rice blast. The combination of pyrimidine tetrazole and tricyclazole, blastamide, rice blastling, and kasugamycin with different mechanisms has unexpected effects, not only has a significant synergistic effect, but also can significantly improve the resistance to rice blast. The control effect, reduce the dosage, reduce the cost of control, and it is safe for crops

Embodiment 1

[0057] Weigh 8% tetrazole pyrimide, 22% rice blastling, 5% alkylphenol polyoxyethylene ether phosphate, 6% alkylnaphthalene sulfonate formaldehyde condensate, 4% sodium lauryl sulfate, Kaolin is added to 100% by weight. The above-mentioned raw materials are mixed, pulverized by ultra-fine airflow, and mixed to prepare 30% pyrimidine tetrazolium wettable powder.

Embodiment 2

[0059] Weigh 10% tetrazole pyridoxine, 2% kasugamycin, 4% alkylnaphthalene formaldehyde condensate sodium sulfonate, 5% alkylnaphthalene sulfonate formaldehyde condensate, 6% alkylnaphthalene sulfonate, 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 12% tetrazole pyridine·kasugamycin wettable powder.

Embodiment 3

[0061] Weigh 5% tetrazole pyrimide, 25% tricyclazole, 8% polycarboxylate TERSPERSE 2700, 6% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate) 5% pull open powder BX (dibutyl Sodium naphthalenesulfonate), 4% sodium dodecylbenzenesulfonate, and attapulgite 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 30% pyrimidine tetrazole·tricyclazole water-dispersible granules.

Abstract

The invention discloses a bactericidal composition containing picarbutrazox and application of the bactericidal composition. Effective components comprise the picarbutrazox as a first active component and one of tricyclazole, fenoxanil, isoprothiolane and kasugamycin as a second active component, wherein the weight ratio of the first active component to the second active component is (1 to 80):(60 to 1), preferably (1 to 60):(40 to 1). The composition can be prepared into agriculturally-allowable dosage forms of wettable powder, a water dispersible granule, a suspending agent, suspension emulsion, emulsion in water, microemulsion, an aqueous capsule suspension, a microcapsule suspension-suspending agent, a dispersible oil suspending agent and dry suspension. The bactericidal composition disclosed by the invention is reasonable in composition and good in sterilization effect; in addition, the activity and the sterilization effect of the bactericidal composition are not simple superposition of the activities of all the components; compared with the conventional single preparation, the bactericidal composition has the advantages of obvious sterilization effect, remarkable synergistic effect and good safety to crops; the bactericidal composition disclosed by the invention has a remarkable prevention and control effect on pyricularia oryzae cav.

Description

technical field [0001] The invention relates to a bactericidal composition, which is composed of a first active ingredient pyrimidine tetrazole and a second active ingredient tricyclazole, rice blastamide, rice blastling, kasugamycin and an auxiliary agent, belonging to the complex Dispensing pesticide technical field. 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 rice blast, blight and Pythium, focusing on preventive and protective effects, and has cross-layer systemic and certain therapeutic activity. [0003] Tricyclazole, English name tricyclazole, chemical name: 5-methyl-1,2,4-triazolo(3,4-b)benzothiazole. It is a ...
