[0086] 40% active compound (20.0% 2-mercaptobenzothiazole zinc and 20.0% fluoroamide composition), EO / PO block polyether 1.0%, acrylic acid homopolymer sodium salt 1.0%, polymer polycarboxylate 4.0 %, ethylene glycol 2.0%, epoxidized soybean oil 5.0%, urea 2.0%, silicone defoamer 0.1%, deionized water to 100%, and put it into a high-shear homogeneous emulsifier for 30 minutes at high speed , and then transported to a sand mill, 1-3 times of circular sanding to obtain 40% active compound suspension.

Embodiment 2

[0088] 40% active compound (20.0% 2-mercaptobenzothiazole zinc and 20.0% flufenadine composition), EO / PO block polyether 1.0%, maleic acid-acrylic acid copolymer sodium salt 5.0%, urea 2.0 %, silicone defoamer 0.1%, and deionized water to 100%, put it into a high-shear homogeneous emulsifier for 30 minutes at high speed, then transport it to a sand mill, and cycle sanding 1-3 times This gives a 40% active compound suspension.

[0089] 2. Microcapsule suspension

Embodiment 3

[0091] 25% active compound (10.0% zinc 2-mercaptobenzothiazole and 15.0% thiofluxamide composition) preparation method: 10.0% zinc 2-mercaptobenzothiazole, 15.0% thiofluxamide, and 1.0% alkylnaphthalene sulfonate %, acyl glutamate 2.0%, silicone defoamer 0.1%, polyphenyl polymethylene polyisocyanate PAPI3% and diphenylmethane diisocyanate MDI2%, gum arabic (5%) aqueous solution 10%, to 40.46% of ionized water is fully mixed, and then put into a sand mill for sand grinding until the D90 particle size is 3-5 microns. Start stirring (maintain 700 rpm), then raise the temperature of the sand-milled suspension to 60°C, and slowly add 0.04% triethanolamine at the same time to maintain a stable solidification temperature of the capsule wall material for 8 hours, then add fatty alcohol polyoxyethylene ether Sulfate 1.0%, sodium methylnaphthalenesulfonate formaldehyde condensate 1.0%, urea 2.0%, glycerol 2.0%, aluminum magnesium silicate (2%) aqueous solution 10%, appropriate amount of...

Abstract

The present invention belongs to the field of agriculture, and relates to a sterilization activity compound composition, particularly to a zinc 2-mercaptobenzothiazole and succinate dehydrogenase inhibitor (SDHI) bactericide composition, a preparation and applications thereof. The sterilization composition contains a sterilization activity compound I and a sterilization activity compound II, wherein the sterilization activity compound I is zinc 2-mercaptobenzothiazole, and the sterilization activity compound II is at least one selected from succinate dehydrogenase inhibitor bactericides such as flutolanil, boscalid, fluopicolide, isopyrazim, sedaxane, fluxapyroxad, trifluzamide, bixafen and fluopicolide. With the sterilization activity compound composition of the present invention, the generation of drug resistance of plant diseases can be effectively reduced, and the resistance risks caused by the single use of the SDHI bactericide and the zinc 2-mercaptobenzothiazole can be substantially reduced.

Description

technical field [0001] The invention belongs to the field of agriculture, and relates to a bactericidal active compound composition, in particular to a composition containing 2-mercaptobenzothiazole zinc and a succinate dehydrogenase inhibitor (SDHI) bactericide, as well as its preparation and application. Background technique [0002] Succinate dehydrogenase inhibitor (SDHI) fungicides specifically interrupt the iron-sulfur protein in the active domain SDHB of the enzyme by acting on complex II on the respiratory chain, namely the succinate dehydrogenase complex (succinate dehydrogenase; SDH). The electron transfer between the iron-sulfur cluster [3Fe-4S] in Ip and ubiquinone affects the respiration of pathogenic fungi, hinders their energy metabolism, inhibits the growth of pathogenic bacteria, and leads to their death, thereby achieving the purpose of sterilization. This type of fungicide has the characteristics of specific action, strong efficacy and long-lasting action,...
