Problems solved by technology

[0003] Although fluazinam has good bactericidal activity against many plant disease pathogens, in the actual process of spraying pesticides in the field, a large amount of pesticide liquid bounces and rolls on the surface of the leaves, gathers and loses, and seeps into the river from the surface, which causes both waste of pesticides and endanger the ecological environment

Abstract

The invention provides a bounce-resistant fluazinam suspension agent. The bounce-resistant fluazinam suspension agent comprises: fluazinam, a wetting agent, a dispersing agent, a thicker, a preservative, an antifreezing agent, a suspending assistant, a defoaming agent, a bounce-resistant agent, a bounce-resistant synergist and water. The preparation method of the bounce-resistant fluazinam suspension agent comprises the process steps of mixing, sanding and the like. The particle size of the suspension agent is controlled to be 5 mum or below, and the suspension ratio is more than 90%. The preparation has the characteristics of low dynamic surface tension, good bounce resistance, strong adhesion and the like, and the bounce loss of a fluazinam solution can be reduced on surfaces of leaves,so that the utilization rate of the pesticide is improved greatly, and the dosage of the pesticide is reduced under the condition of ensuring the same pesticide effect; in addition, the cost of pesticide application of a farmer is reduced, and pollution to the environment is reduced.

Description

technical field [0001] The invention relates to a pesticide fungicide, in particular to an anti-bounce type fluazinam suspension and a preparation method thereof. Background technique [0002] Fluazinam is an aniline fungicide, which is an uncoupler for mitochondrial oxidative phosphorylation, and inhibits the infection of pathogenic bacteria by inhibiting spore germination, hyphal breakthrough, growth and spore formation. Fluazinam is suitable for a wide range of crops such as grapes, apples, pears, citrus, wheat, soybeans, potatoes, tomatoes, rice, tea, lawns, etc., with a wide bactericidal spectrum. Very effective against bacteria of the genera Alternaria, Botrytis, Phytophthora, Plasmodium, Sclerotinia and Scrub, such as cucumber botrytis, rot, downy mildew, anthracnose, powdery mildew , stem rot, tomato late blight, apple scab, leaf spot, pear black spot, rust, rice sheath blight, rice blast, grape gray mold, downy mildew, citrus scab, potato late blight , lawn spot d...
