Pesticide composition for preventing and treating sclerotiniose and application thereof

The invention relates to the technical field of agricultural plant protection, in particular to a pesticide composition for preventing and treating sclerotiniose and application of the pesticide composition. The invention provides a pesticide composition. The pesticide composition comprises at least two of thifluzamide, carboxin and Gongzinglingmycin. Thifluzamide is a succinate dehydrogenase inhibitor and inhibits succinic acid dehydrogenase in tricarboxylic acid cycle of germs to cause thallus death. Carboxin belongs to a systemic heterocyclic bactericide, has a wide bactericidal spectrum, and has a growth stimulation effect on crops; the Gongzhou Mountain mycin belongs to a biological agent, is also a broad-spectrum bactericide, has a certain inhibition effect on sclerotiniose, and also can improve the stress resistance of crops. According to the invention, thifluzamide, carboxin and Gongzinglingmycin are combined for application, and test results show that under a certain proportioning condition, the comb
