Embodiment 1

[0026] Embodiment 1 (25% suspending agent)

[0027] The following substances are all percentages by weight: iprodione 5%, tebuconazole 20%, alkyl succinic acid sulfonate 10%, sodium methylene bis-naphthalene sulfonate 5%, tristyrylphenol polyoxyethylene ether Phosphate ester 5%, magnesium aluminum silicate 4%, calcium dodecylbenzenesulfonate 4%, sorbitol 0.5%, ethylene glycol 2%, and the balance is deionized water. Pyrroloquinoline quinone 4wt%, the above formula was pulverized in advance according to the proportion, then added to a sand mill for grinding, and after high-shear mixing, it was prepared to prepare a 25% iprodione·tebuconazole suspension concentrate.

Embodiment 2

[0028] Embodiment 2 (30% suspending agent)

[0029] The following substances are all percentages by weight: iprodione 5%, tebuconazole 25%, sodium methylene dinaphthalene sulfonate 10%, sodium lignosulfonate 15%, tristyrylphenol polyoxyethylene ether phosphate 5% %, sorbitol 3%, methylcellulose 2%, epoxidized soybean oil 5%, sorbitol 0.5%, ethylene glycol 2%, and the balance is deionized water. Pyrroloquinoline quinone 2wt%, the above formula is pre-crushed in proportion, and then put into a sand mill for grinding, after high-shear mixing, it is prepared to prepare a 30% iprodione·tebuconazole suspension concentrate.

Embodiment 3

[0030] Embodiment 3 (40% suspending agent)

[0031] The following substances are all percentages by weight: iprodione 8%, tebuconazole 32%, sodium octadecyl sulfosuccinate 5%, polyvinyl alcohol 10%, polyoxyethylene-polyoxypropylene mixture 5%, yellow 5% raw gum, 5% epoxidized soybean oil, 0.5% sorbitol, 2% ethylene glycol, and the balance is deionized water. Pyrroloquinoline quinone 5wt%, the above formula is pre-crushed in proportion, then added to a sand mill for grinding, and then prepared after high-shear mixing to prepare a 40% iprodione-tebuconazole suspension.

Abstract

The invention discloses an application of a pesticide compound for preventing and controlling gray mold in preventing and controlling tobacco gray mold. Iprodione, tebuconazole and pyrroloquinoline quinone are taken as main active ingredients of the pesticide compound; the weight ratio of iprodione to tebuconazole is (1-6):(1-6); the total weight of iprodione and tebuconazole is 25-40% of the weight of the pesticide compound. The compound, compared with single dosage, has an obvious synergistic effect in preventing and controlling gray mold; the pesticide compound is capable of overcoming anddelaying the drug resistance of pathogenic bacteria; dosage and cost of pesticide are reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticide application, and relates to a pesticide composition, which is used for preventing and treating tobacco gray mold. Background technique [0002] Tobacco is the raw material of the cigarette industry and the main economic crop in our country, occupying an important position in the national economy. Tobacco gray mold (Tobacco gray mold) is a very harmful disease in tobacco production. The pathogenic bacterium is Botrytis cinerea, which has a wide range of hosts and is highly harmful. The diseased plant rate can reach 100%, the diseased leaf rate is generally 10% to 20%, and can reach more than 80% in serious cases, usually resulting in a decline in tobacco leaf output and quality, causing serious economic losses to tobacco farmers. [0003] With the expansion of the scale of intensive tobacco production in my country and the changes in crop layout and cultivation system, the occurrence of tobacco ...
