Abstract

The invention discloses an agent used for preventing and treating damping off of florence fennel. The agent comprises the following components in parts by weight: 14-18 parts of 70% fosetyl.mancozeb wettable powder, 6-8 parts of 64% oxadixyl.mancozeb wettable powder, 4-6 parts of 72% Dubang curzate wettable powder, 4-8 parts of alkylphenol ethoxylate formaldehyde condensates, 3-7 parts of gelatin, 6-9 parts of diethylaminoethyl hexanoate, 15-20 parts of methanol, 4-9 parts of polyoxyethylene castor oil ether, 1-3 parts of chlorogenic acid, 4-8 parts of hypericin and 30-40 parts of water. A use method comprises the following steps: proportionally allocating and mixing the components and stirring the components uniformly to obtain the agent for prevention and treatment; then spraying the agent around affected plants after diluting the agent for prevention and treatment. The agent has good prevention effects, is convenient to use, reduces the pesticide consumption, reduces environmental pollution and is beneficial to ecological balance.
