Abstract

The invention relates to a bactericidal composition having a synergistic effect. The active ingredients of the bactericidal composition comprise propamidine and pyrimorph in a weight ratio of 1-60:80-1; and wettable powder, water dispersion and suspension can be prepared by adding an assistant and an excipient into the active ingredients. The bactericidal composition can effectively preventing and controlling gray mold, downy mildew, epidemic disease and the like in fruits and vegetables.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a bactericidal composition containing propaneamidine and fenpyrimorph. technical background [0002] Oomycete is a kind of serious plant pathogen in agricultural production at present. It has the characteristics of short generation, large spore production, short incubation period, many times of infection, strong damage to host plants, and fast epidemic speed. . Diseases caused by oomycetes account for about 20% of vegetable diseases and are a large category of vegetable diseases. There are two main types of chemical control agents for oomycetes: protective fungicides and systemic fungicides. Protective fungicides mainly include carbendazim, mancozeb, chlorothalonil and copper preparations. These agents have a broad bactericidal spectrum, stable efficacy, and strong protective effect. However, after the invasion of germs, the control effect is poor, and there is basically no t...
