Embodiment 1

[0018] Embodiment 1: 20% pyridoxazole · medistrobin microcapsule suspension

[0019] The following substances are all percentages by weight: pyridoxazole 15%, metrastrobin 5%, polycaprolactone 2%, sodium carboxymethylcellulose 2%, trimethylbenzene 10%, sec-butyl acetate 10%, Castor oil polyoxyethylene ether 5%, polyoxyethylene polyoxypropylene ether block copolymer 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 20% pyridoxazole-mediclostrobin microcapsule suspension can be prepared.

Abstract

The invention discloses a sterilization composition containing SYP-Z048 and meptyldinocap. The sterilization composition comprises effective components including SYP-Z048 and meptyldinocap, and common auxiliary components, wherein the weight ratio of the SYP-Z048 to the meptyldinocap in the composition is (20:1) to (1:10); a lot of indoor and outdoor tests show that the sterilization composition has a remarkable synergistic effect on a plurality of types of diseases which endanger the growth of plants, particularly botrytis and powdery mildew; and meanwhile, the utilization amount of pesticides is reduced and the residual amount of the pesticides on the plants is reduced, so that the pollution to the environment is alleviated, the drug resistance of pathogenic bacteria is delayed and the service life of the pesticides is prolonged.

Description

technical field [0001] The invention relates to a pesticide fungicidal composition and its application field, in particular to a fungicidal composition with pyridoxazole and medistrobin as active ingredients, which is mainly used for preventing and treating gray mold and powdery mildew of crops. Background technique [0002] Pyridoxazole is an oxazoline fungicide, which belongs to the sterol synthesis inhibitor. It has protective and therapeutic effects, has good systemic properties, and can effectively control the occurrence and damage of leaf diseases through root and leaf stem absorption. The compound has good control effect on gray mold on tomato, cucumber and grape, powdery mildew on wheat and cucumber and the like. [0003] Metystrobin, which belongs to the dinitrophenol fungicides, acts on various stages of the life cycle of pathogenic bacteria, inhibits spore germination, inhibits fungal respiration, causes cell metabolism disorder, and causes pathogenic bacteria cel...
