Embodiment 1

[0045] Weigh 10% boscalid, 15% epoxazole, 3% polycarboxylate, 3% polyoxyethylene polyoxypropylene ether block copolymer, 1% magnesium aluminum silicate, 0.2% xanthan gum, 5% ethylene glycol, 0.1% formaldehyde, 0.3% silicone defoamer (trade name: s-29 produced by Nanjing Sixin Applied Chemicals Company), and deionized water to 100% by weight. The above raw materials are mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to a particle size of D 90 A 25% boscalid·epiconazole suspension was prepared after the thickness was less than 10 μm.

Embodiment 2

[0047] Weigh 8% boscalid, 12% prothioconazole, 3% polyoxyethylene polyoxypropylene ether block copolymer, 1.5% fatty alcohol polyoxyethylene ether phosphate, 2% sodium alkylnaphthalene sulfonate , 1% magnesium aluminum silicate, 0.4% bentonite, 5% glycerin, 0.1% benzoic acid, 0.3% organic silicon defoamer s-29, deionized water added to 100% by weight. The above raw materials are mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to a particle size of D 90 A 20% boscalid·prothioconazole suspension was prepared after the thickness was less than 10 μm.

Embodiment 3

[0049] Weigh 6% boscalid, 18% propiconazole, 4% alkyl polyoxyethylene ether sulfonate, 3% triphenylethylphenol polyoxypropylene polyoxyethylene block polymer, 0.2% bentonite, 5% % propylene glycol, 0.2% benzoic acid, 0.5% octanol, deionized water added to 100% by weight. The above raw materials are mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to a particle size of D 90 A 24% suspension concentrate of boscalid·propiconazole was prepared after the thickness was less than 10 μm.

Abstract

The invention discloses application of a boscalid-containing bactericidal composition to prevention and treatment of rot diseases. The composition is prepared from active components including boscalid and triazole fungicide, and an auxiliary agent, wherein the triazole fungicide is selected from one of tebuconazole, flusilazole, epoxiconazole, prothioconazole, propiconazole and hexaconazole; the weight ratio of the boscalid to the triazole fungicide ranges from (40 to 1) to (1 to 40), preferably (20 to 1) to (1 to 20). The composition disclosed by the invention can be prepared into agriculturally acceptable suspension agents, water dispersible granules, paste, ointment, suspension emulsion, dispersible oil suspension emulsion and missible oil. The boscalid-containing bactericidal composition has reasonable components, has good prevention and treatment effects on the rot diseases of fruit trees and can be used for promoting wound healing and reducing the recurrence rate of the rot diseases; compared with an existing single preparation, the boscalid-containing bactericidal composition has remarkable prevention and treatment effects, also has a remarkable synergistic effect, is low in drug cost and good in safety, and meets the safety requirements of pesticide preparations.

Description

technical field [0001] The invention relates to the application of a fungicidal composition containing boscalid in the prevention and treatment of rot. The composition is composed of active ingredients boscalid, triazole fungicides and auxiliary agents, and belongs to the technical field of compound pesticide application . Background technique [0002] Boscalid, English name boscalid, chemical name: 2-chloro-N-(4'-chlorobiphenyl-2-yl) nicotinamide. Transferred in plants through foliage penetration, inhibits mitochondrial succinate dehydrogenase, hinders tricarboxylic acid cycle, causes amino acid, sugar deficiency, energy reduction, interferes with cell division and growth, has neurological activity on diseases, and has protection and treatment effect. Inhibits spore germination, bacterial tube elongation, hyphal growth and spore mother cell formation, the main stages of fungal growth and reproduction, and the bactericidal effect is directly caused by the parent active sub...
