Flusilazole-and kresoxim methyl bactericide composition and its prepn process

Abstract

The present invention relates to bactericide composition and its preparation and application. The bactericide composition consists of Flusilazole and BAS 490F in the weight ratio of 0.02-50 as the active components, into which proper amount of assistant or carrier is added to compound emulsion oil, wettable powder, water emulsion, suspension, water dispersed granule or oil preparation. It may be used in preventing and controlling various kinds of plant diseases caused by pathogenic fungi. The indoor experiment proves its obvious synergistic effect and delayed resistance of pathogenic fungi.

technical field

[0001] The invention relates to a fungicide composition, a preparation method and an application. Background technique

[0002] Flusilazole is an excellent variety among azole fungicides. It has excellent control effects on various diseases caused by ascomycetes, basidiomycetes, and half-knowledge fungi, and is widely used in apples, pears, cucumber scab, powdery mildew, tomato leaf mold, grape black pox, house blight, Chemical control of vegetable powdery mildew, bean rust and other diseases. It has both preventive and curative effects. The mechanism of action of the fungicide is to inhibit the biosynthesis of ergosterol in fungi, and ergosterol is a constituent of fungal cell membranes. Therefore, ergosterol is inhibited, which can lead to damage of cell membrane and death of bacteria. This agent has been used in my country since the 1990s, and first achieved great success in the prevention and treatment of pear and cucumber scab. Since then, it has co...
