Embodiment 1

[0017] Embodiment 1: 18% fluazinam·shenzimycin microcapsule suspension

[0018] The following substances are all percentages by weight: Fluazinamine 16%, Shenzimycin 2%, Polyether polyol 1.5%, Diphenylmethane diisocyanate 1.5%, Trimethylbenzene 10%, Fatty acid methyl ester 10%, Castor oil polyol Oxyethylene ether 5%, sodium methylene bis-naphthalene sulfonate 3%, sodium hydroxide 2%, deionized water to make up to 100%. Mix the above-mentioned active ingredient, polymer capsule wall material, and solvent to dissolve into a uniform oil phase, and under shearing conditions, add the oil phase to the aqueous phase solution containing emulsifier, dispersant, and pH regulator Make up with deionized water, the two materials react at the oil-water interface to form a polymer capsule wall, and then the 18% fluazinam·shenzimycin microcapsule suspension can be prepared.

Abstract

The invention discloses a bactericidal composition containing fluazinam and shenqinmycin. The bactericidal composition comprises fluazinam, shenqinmycin and common auxiliary ingredients, wherein the weight ratio of fluazinam to shenqinmycin is 20:1-1:1. A large quantity of indoor and outdoor experiments show that the bactericidal composition has the significant synergistic effect on multiple diseases damaging agricultural production, the pesticide using amount is decreased, the residual amount of the pesticide on plants is decreased, pollution to the environment is reduced, generation of the pesticide resistance to the diseases is delayed, and the service life of the pesticide is prolonged.

Description

technical field [0001] The invention relates to a pesticide bactericidal composition and its application field, in particular to a bactericidal composition with fluazinam and shenazamycin as active components, which is mainly used for the prevention and control of diseases on crops. Background technique [0002] Fluazinam (Fluazinam) is a new type of substituted aniline, broad-spectrum fungicide, and its mechanism of action is a mitochondrial oxidative phosphorylation uncoupler that inhibits the respiration of pathogens. For rapeseed sclerotinia, rice sheath blight and rice blast, wheat sheath blight, wheat scab, wheat powdery mildew, fruit and vegetable powdery mildew, downy mildew, gray mold, rot, dry rot , Anthracnose, ring spot and leaf spot, black pox and rot and other diseases. There is no cross-resistance to fungicides currently on the market such as benzimidazoles, dicarboximides, succinate dehydrogenase inhibitors, electron transport chain complex III inhibitors an...
