Of the germicide composition, captan and triazole germicide compound have the weight ratio of 1/40 to 40 and account for 1-90 wt%. The composition has proper amount of functional assistants and carrier added for being prepared into suspension, wettable powder, water dispersed granule, microemulsion, etc. The composition may be used for preventing and treating diseases caused by oomycetes, ascomycete, basidiomycete and other germs.
Description
Technical field:
The present invention relates to a kind ofly contain captan and at least a triazole bactericidal agent compound, and the preparation of some formulation of said composition and application technology, the microbicide compositions technical field belonged to.
Background technology:
Captan is a kind of broad spectrum activity protective fungicide that comes out nineteen fifty-three.Its mechanism of action mainly is the metabolism that influences the thalline pyruvic acid, and plurality of enzymes is had the obvious suppression effect, also can reduce the metabolism of phosphorus, reduces the content of adenosine triphosphate in the thalline, and can stop the conidial bulk storage of some germs.Can be widely used in preventing and treating the multiple diseases that takes place on fruit tree, vegetables and the various economic crops, foliar spray and seed dressing all can, effective to diseases such as cucumber anthracnose, downy mildew, early blight of tomato, potato late blight, downys mildew of garpe, but because this medicament is not inhaled therapeutic action in having, in a single day disease spreads and just is difficult to control, therefore uses drug effect relatively poor at the disease occurrence in peak period; And the captan applicating history is long, and resistance problem is very outstanding.Therefore, selecting other efficient germicides composite with it is to resist resistance, delaying drug resistance development, a kind of important channel that prolongs its service life.
The present application people has carried out series of studies and application test to the complex preparation of captan, finds that captan and triazole bactericidal agent are composite to have a notable synergistic effect.Its action principle of triazole bactericidal agent mainly is to suppress the biosynthesis of ergosterol in the fungi, can be used as seed treatment and foliar spray agent, active high, lasting period is long, safety is good, outstanding to preventive effects such as wheat rust, powdery mildew, sigatoka, rings rot of apple, but relatively poor to oomycetes disease effects such as downy mildew of garpe, eqpidemic diseases.
