AI Technical Summary

Problems solved by technology

The seedlings are too dense, the seedlings are not thinned in time, and the temperature is too high to easily induce the disease
Due to the time-consuming and labor-intensive conventional control methods and the poor effect, it seriously affects the work of vegetable seedling cultivation and restricts the development of vegetable production.

Abstract

The invention discloses a combined pesticide for preventing and treating damping-off of vegetables in a seedling stage. The combined pesticide comprises the following components in percentages by mass: 20.0-50.0% of validamycin, 10.0-30.0% of fulvate, 3.0-5.0% of brassin, 25.0-40.0% of ethanol, 1.0-10.0% of benzyl vinyl phenol polyoxyethylene ether, 1.5-10.0% of a pesticide emulsifier 0203A, 1.0-5.0% of polyethylene glycol and 0.5-5.0% of polypropylene glycol. Compared with the conventional pesticide for preventing and treating damping-off, the combined pesticide has a remarkable effect, and can be widely used for preventing and controlling damping-off of various crops such as wheat, rice, cotton, peanuts, flowers and vegetables. The effect of preventing and treating the damping-off of thevegetables in the seedling stage is particularly remarkable, effects of protecting seedlings, improving roots and promoting growth are achieved, the vegetable growth potential is high, the commodityis good, and thus, the combined pesticide is worthy of being popularized widely.

Description

technical field [0001] The invention relates to a combined drug for preventing and treating vegetable seedling blight and a preparation method thereof, belonging to the technical field of pesticides. Background technique [0002] The blight is mainly caused by the infection of Rhizoctonia solani Deuteromycotina fungus, and has a wide range of hosts. In addition to Solanaceae, melon vegetables, etc., some leguminous, cruciferous and other vegetables can also be invaded. It mainly harms the base of seedling stems or underground roots. It was oval or irregular dark brown lesions at first, and the lesions were gradually sunken and overflowed. When the lesion expands and circles the stem, it finally dries up and dies. The pathogen survives the winter in the soil or diseased tissue with mycelium and sclerotia, and has a strong saprophytic nature. Generally, it can survive in the soil for 2-3 years and spread through rainwater, running water, bacteria-carrying compost and agricu...
