Abstract

The invention provides a fluopicolide-containing compound bactericide which comprises active ingredients and auxiliary agents, wherein the active ingredients comprise fluopicolide and strobilurin bactericide with the weight ratio of 1-10: 1-90; and the strobilurin bactericide comprises one or more of pyraclostrobin, azoxystrobin, pyrametostrobin, enestroburin, pyraoxystrobin, flufenoxystrobin. The fluopicolide-containing compound bactericide is remarkable in synergism in the aspect of preventing and controlling fruit and vegetable oomycetes diseases. The compound bactericide is good in fast-acting property and persistence, unique in mechanism of action and multiple in acting sites, and can effectively delay the occurrence and development of bactericide resistance of pathogenic bacteria. The compound preparation is simple in preparation technology, low in cost, remarkable in economical benefit, wide in disease prevention spectrum and high in biosecurity.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a biocide containing a heterocyclic compound and a preparation method thereof. Background technique [0002] Oomycete diseases of fruits and vegetables are caused by the infection of oomycetes of the flagellate subphylum. Among them, oomycetes such as Phytophthora, Downy mildew, and Pythium are important pathogens of fruits and vegetables, which mainly harm fruit crops such as grapes and Brassicaceae, Solanaceae, Cucurbitaceae and other vegetable crops cause damping-off, cotton rot, blight, cotton blight, downy mildew and root rot of fruits and vegetables, resulting in a substantial reduction in production or even failure [1] . Especially downy mildew and Phytophthora have a short incubation period and many times of re-infection. The pathogens can develop rapidly within a growing season of the plant and cause disease epidemics, resulting in serious losses in agricultural pr...
