Abstract

An agricultural chemical 'Viridin-dimethomorph' in the form of dispersing tablet or particle is proportionally prepared from viridin, dimethomorph, adhesive, disintegrant, wetting agent, disperser and filler through fermenting viridin, mixing with the sieved mixture powder of others, and tabletting or granulating. Its advantage is no environmental pollution.

Description

technical field [0001] The invention belongs to the field of biological pesticides, and relates to an agricultural fungicide Trichoderma viride·dimethomorph water-dispersible tablet or water-dispersible granule and a preparation method thereof. Background technique [0002] Trichoderma spp. is a fungus belonging to the subphylum Deuteromycota, Hyphospora, Hyphospora, and Leucospora. It is a kind of fungus that is ubiquitous in nature and is widely distributed in various plant residues, soil and air. It is a kind of soil-dwelling fungus that is widely distributed. It has inhibitory effect on plant pathogenic fungi and is used to prevent and control soil-borne diseases. , leaf disease and grape ear rot and wood preservation, and can promote the growth of certain plants. [0003] Dimethomorph is a new type, broad-spectrum, high-efficiency, systemic fungicide, which integrates protection and treatment, has systemic treatment for fungal diseases, and has the effects of killing s...
