Embodiment 1、10

[0028] Embodiment 1,10% fluazinam · pyrimethanil microemulsion

[0029] According to fluazinam 5%, pyrimethanil 5%, toluene 8% (solvent), Nongru No. 500 8% (emulsifier), Nongru No. 1600 5% (emulsifier), isopropanol 10% (solvent ), ethylene glycol 5% (antifreeze) and weigh each component, fully mix the pesticide with emulsifier, solvent, and co-solvent to form a uniform and transparent oil phase, slowly add distilled water or deionized water to 100% under stirring , forming a water-in-oil emulsion, and then heated with stirring to make it rapidly phase-invert into an oil-in-water type, and cooled to room temperature to make it equilibrated, and a stable 10% fluazinam·pyrimethanil microemulsion was prepared.

[0030] The microemulsion, 50% fluazinam suspension, and 40% pyrimethanil suspension were used for field efficacy tests at 180 g / ha, 250 g / ha, and 400 g / ha of active ingredients respectively. The control effect of 3 days and 10 days after taking medicine is more than 90%, ...

Embodiment 2、26

[0033] Embodiment 2, 26% fluazinam · procymidone microemulsion

[0034] According to fluazinam 25%, procymidone 1%, N-methylpyrrolidone 10% (solvent), isopropanol 15% (solvent), agricultural milk 500 # 5% (emulsifier), Nongru 1601 # 5% (emulsifier), water to make up to 100% of the formulation ratio to weigh each component. The original drug, solvent and emulsifier are added together to dissolve into a uniform oil phase; under stirring, the oil phase is mixed with the water phase to prepare a stable 26% fluazinam·procymidone microemulsion.

[0035] The microemulsion, 50% fluazinam suspension, and 50% procymidone wettable powder were subjected to field efficacy tests at 190 g / ha, 250 g / ha, and 600 g / ha of active ingredients respectively. After 3 days and 10 days after the medicine, the control effect is more than 90%, which is better than that of a single dose.

Embodiment 3、31

[0038] Example 3, 31% fluazinam·sclerotin suspension concentrate

[0039] According to fluazinam 1%, sclerotium 30%, sodium methylnaphthalene sulfonate formaldehyde condensate 10% (dispersant), xanthan gum 2% (thickener), bentonite 1% (thickener), di Sodium alkyl sulfate 3% (wetting agent), glycerin 5% (antifreezing agent), and water make up to 100% formula ratio to weigh each component. Mix active ingredients, dispersant, wetting agent and water evenly, grind or high-speed shear to get semi-finished products, add water after analysis, mix evenly and filter to get 31% fluazinam·sclerotin suspending agent .

[0040] The suspension concentrate, 50% fluazinam suspension concentrate, and 40% sclerotia net wettable powder were respectively carried out field efficacy tests according to the active ingredients 160 g / ha, 250 g / ha, and 240 g / ha. After 3 days and 10 days after the medicine, the control effect is more than 90%, which is better than that of a single dose.

Abstract

The invention discloses a bactericide composition comprising the effective components of (A) fluazinam and (B) one of pyrimethanil, procymidone or dimethachlone, wherein the mass ratio of the A and the B is 1:50-50:1. The composition has obvious synergistic action and high preventing effect, is suitable for preventing and treating various diseases on melons, fruits and vegetables and is especially suitable for preventing and treating gray mold; and the preventing effect in fields can reach more than 90%.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition containing fluazinam. Background technique [0002] Botrytis cinerea belongs to a kind of common gray rot, and the pathogen is Botrytis cinerea (Botrytiscinerea), which belongs to the subphylum Deuteromycota and the fungus of the genus Botrytis. The pathogen mainly harms inflorescences, young fruits and fruits that are about to ripen. Botrytis cinerea occurs heavily in low-lying vineyards with overgrown new shoots, poor ventilation and light transmission, extensive management, overgrown weeds, insufficient fertilization, and severe insect damage. Because Botrytis cinerea can spread and harm occurs, it often causes the death of large areas of plants, resulting in reduced yield and poor quality, which seriously restricts the development of grape production. At present, the main chemical agents used are promethazine and promethazine. Due to the abnormal gen...
