Abstract

The invention relates to a wettable powder containing Trichoderma harzianum T‑22 and copper ammonia and its preparation method and application, which relate to the field of agriculture, in particular to a wettable powder for preventing and treating soil-borne diseases of crops. Its purpose is to provide a wettable powder containing Trichoderma harzianum T-22 and ammonia copper with good control effect, wide control spectrum, safety and pollution-free, and its preparation method and application. The present invention contains the wettable powder of Trichoderma harzianum T-22 and copper ammonia, and the wettable powder comprises Trichoderma harzianum T-22 and copper ammonia. The product of the present invention is compounded with Trichoderma harzianum T-22 and ammonia copper to prevent and treat soil-borne diseases of crops. Once used, it can effectively control root soil-borne diseases, increase the control effect, and increase the control spectrum at the same time. Soil-borne diseases mixed with pathogenic bacteria have a good control effect.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a wettable powder for preventing and treating soil-borne diseases of crops. Background technique [0002] Trichoderma harzianum T-22 is a preventive microbial fungicide, which can be used in the process of planting organic crops. It has a good control effect on root diseases, and the drug effect lasts up to three months, but Trichoderma harzianum T-22 is slow to take effect as a microbial agent, and the effect of preventive use is relatively good, and the effect is slow after the onset of the disease. Copper preparations can prevent and treat fungal diseases as well as bacterial diseases. They have both protective and preventive effects, and have certain therapeutic and eradicating effects. Copper lanthanide is a copper glycine complex, which can effectively reduce common Copper preparations are prone to phytotoxicity, and can also be used in organic planting production. The combinat...
