Problems solved by technology

The principle of action of triazole fungicides is mainly to inhibit the biosynthesis of ergosterol in fungi. They can be used as seed treatment agents and foliar sprays. They have high activity, long duration and good safety. They are effective against wheat rust, powdery mildew, Excellent control effect on banana leaf spot, apple ring spot, etc., but less effective on grape downy mildew, blight and other oomycete diseases

Embodiment Construction

[0048] The effective components in the examples are captan and a triazole fungicide—tebuconazole. Embodiment (taking suspending agent as example):

[0049] 1, weigh the fungicide composition raw material by weight percentage: captan 5kg (weight ratio is 5%), tebuconazole 40kg (weight ratio is 40%), additive is 55kg (weight ratio is 55%), wherein Agent polyoxyethylene triphenyl phosphate 6kg, propylene glycol 5kg, xanthan gum 9kg, filler white carbon black, water 35kg, pour the weighed raw materials into a mixing tank and stir evenly, and grind them in a coarse and fine sand mill for 0.5-1.5 hours , and then mixed with a thickener, and after stirring for 0.5-1.5 hours in a mixing tank, the finished product of the combined fungicide is made.

[0050] 2. Weigh the fungicide composition by weight percentage and prepare raw materials: captan 32kg (weight ratio is 32%), tebuconazole 4g ​​(weight ratio is 4%), additive is 64kg (weight ratio is 64%), wherein Auxiliary polyoxyethylen...

Abstract

The present invention discloses synergistic germicide composition with active components including captan and at least one kind of triazole germicide compound. 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: [0001] The invention relates to a compound containing captan and at least one triazole fungicide, as well as the preparation and application technology of certain dosage forms of the composition, belonging to the technical field of fungicide compositions. Background technique: [0002] Captan is a broad-spectrum protective fungicide that came out in 1953. Its mechanism of action is mainly to affect the metabolism of pyruvate in the bacteria, and it has obvious inhibitory effect on various enzymes. It can also reduce the metabolism of phosphorus, reduce the content of adenosine triphosphate in the bacteria, and prevent the release of conidia of some pathogenic bacteria. It can be widely used in the prevention and control of various diseases on fruit trees, vegetables and various economic crops. It can be sprayed on the leaves and seed-dressed. However, since the drug has no systemic therapeutic effect, once the disease spreads, it is difficult to control, so...
