Abstract

The invention discloses a pesticide composition containing cyprodinil and propamidine. The pesticide composition contains commonly-used auxiliaries, cyprodinil and propamidine, wherein weight ratio of cyprodinil to propamidine is 30:1-1:7, and the total weight of cyprodinil and propamidine in the pesticide composition is 3-90 wt%. After compounding of cyprodinil and propamidine, the pesticide composition has an obvious synergistic effect, and dosage of active ingredients of the compounded medicine is obviously reduced than that of a separately-used ingredient. The pesticide composition is suitable for preventing and curing crop diseases caused by pathogenic fungi, especially crops' gray mold caused by Botrytis pathogens and crops' sclerotiniose caused by Sclerotinia pathogens.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition containing cyprodinil and propamidine. Background technique [0002] Cyprodinil is a methionine biosynthesis inhibitor with protective, therapeutic and systemic activities. It is mainly used to control crop diseases such as botrytis cinerea, sclerotinia, powdery mildew, scab and leaf spot. [0003] Propamidine, English common name Propamidine, is an aromatic diamidine compound. Propamidine is a systemic fungicide, which can be absorbed, distributed and metabolized in plants, and has protective and therapeutic effects. Botrytis cinerea caused by crops. [0004] The mixing of different pesticide varieties is a common method to control agricultural resistant diseases. Through the screening of pesticide formulas, screening out reasonable formulas can effectively improve the actual control effect, reduce the dosage of pesticides, reduce costs, and delay the emergenc...
