Abstract

The invention belongs to the field of agricultural chemicals, and particularly relates to a bactericide capable of preventing and treating the gray mold of tomatoes and a preparation method of the bactericide. The bactericide is prepared from sodium fluoride, silico fluoride, fludioxonil, trichoderma reesei and an activator, wherein the activator is prepared from oligosaccharins, dodecyl sodium sulphate, sodium lignosulfonate, nekal bx, diatomite and wheat straw powder. According to the bactericide and the preparation method thereof, disclosed by the invention, the activator is added, so that the disinfectant effect of the bactericide can be effectively improved; the fludioxonil and the trichoderma reesei are processed firstly, and then the fludioxonil and the trichoderma reesei which are processed are combined with other components, so that the component is notable in effect and can have the effect of effective sterilization. The sodium fluoride, the silico fluoride, the fludioxonil, the trichoderma reesei and the activator are matched for use, so that the drug property of the bactericide disclosed by the invention is strong, the consumption is low, environmental pollution is reduced, and the bactericide can be used for a long term.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a fungicide for preventing and treating gray mold of tomato and a preparation method thereof. Background technique [0002] Botrytis cinerea is a worldwide important disease caused by Botrytis cinerea, which can harm more than 200 crops such as tomato, cucumber, strawberry and grape, especially in protected tomato, causing flowers, leaves and Fruit rot. When the leaves are infected, they usually expand inwards in a "V" shape from the edge of the leaves, water-stained at the beginning, light brown, with irregular edges, and faint ring patterns can be seen. When the humidity is high, the diseased part will produce gray mold, causing the leaves to die. When the stems become ill, they start as water-soaked dots, and then expand into oblong or strip-shaped spots. When the humidity is high, a gray-brown mold layer grows on the lesions, and when it is severe, it causes the diseas...
