Abstract

The invention discloses a chemical composition for preventing and curing tomato fusarium wilt, which comprises active ingredients of prochloraz and fludioxonil. The chemical composition takes prochloraz and fludioxonil as the main active ingredients and follows the acting principle that prochloraz inhibits biosynthesis of sterol so as to achieve the effect of internal absorption and conduction inplants, so that the chemical composition has strong internal absorption, quick effect and long duration; fludioxonil inhibits glucose phosphorylation related transfer to inhibit growth of fungal mycelium, thereby killing bacteria eventually. The fungicide prepared by mixing prochloraz and fludioxonil has the beneficial effects that the consumption of the fungicide is reduced while the optimal control effect is achieved through obvious synergism, the use cost is lowered, the residue of pesticides in crops is reduced, and the environmental pollution is alleviated.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pharmaceutical composition for preventing and treating tomato wilt. Background technique [0002] Tomato Fusarium wilt, also known as wilt disease, mostly occurs during the flowering and fruiting period of tomatoes, and local damage occurs, and the whole plant becomes diseased. In the early stage of the disease, only the lower leaves of the plant turn yellow, but most of them do not fall off. As the disease progresses, the diseased leaves turn yellow and brown from bottom to top. Except for a few top leaves that are intact, the rest are necrotic or scorched. Sometimes the leaves on one side of the diseased plant are drooping, while the leaves on the other side are still normal. [0003] General control methods for tomato fusarium wilt include: 1. Select disease-free seeds and seed treatment: select and retain seeds from disease-free plants. For seed disinfection, 0.3-0.5% of 50% cap...
