Abstract

The invention relates to hot fogging concentrate for controlling downy mildew of cucumbers in plastic greenhouses. The hot fogging concentrate is characterized by taking dimethomorph or azoxystrobin, chlorothalonil, cymoxanil, metalaxyl, oxadixyl, enestroburin and flumorph as the active ingredients and containing such auxiliaries as an emulsifier, a dispersing agent, a solvent, a viscosity modifier, a defoamer and the like to prepare oil suspension hot fogging concentrate. The active content of the drugs in the hot fogging concentrate is 10-40% and the hot fogging concentrate is specially used by hot fogging machines and is especially effective for downy mildew of cucumbers in the greenhouses or protected cultivation. The hot fogging concentrate can be widely used for controlling downy mildew, phytophthora root rot and other diseases of watermelons, summer squashes, tomatoes, chillies, eggplants and the like in the greenhouses or protected cultivation and has great application value and quite obvious economic and social benefits.

Description

technical field [0001] The thermal aerosol agent for preventing and treating cucumber downy mildew in plastic greenhouses according to the present invention contains dimethomorph or azoxystrobin, chlorothalonil, cymoxanil, metalaxyl, oxaxyl, enoxastrobin, Flumorph, emulsifier, dispersant, solvent, viscosity modifier and defoamer and other additives made of oil-suspended hot aerosol (hotfoggingconcen-trate) composition. [0002] At the same time, the invention relates to the application of a thermal aerosol agent for preventing and treating cucumber downy mildew in plastic greenhouses and its application method. The hot aerosol agent can also be widely used in the prevention and treatment of downy mildew, phytophthora and other diseases such as watermelon, zucchini, tomato, pepper and eggplant cultivated in facilities such as plastic greenhouses, and has great application value and remarkable economic and social benefits. Background technique [0003] Dimethomorph is a fungi...
