Abstract

The invention relates to the technical field of tobacco planting, in particular to a tobacco disease control method. The tobacco disease control method comprises the following steps that (a), tobaccois subjected to seedling raising in a medium containing a microbial agent; (b), transplanting is conducted in the growth time, the microbial agent is sprayed to tobacco seedlings before transplanting;c), 25-30 days after the tobacco is transplanted, a mixture of the medium containing the microbial agent and tobacco fertilizer is applied to the roots of the tobacco, wherein the active ingredientsof the microbial agent comprise bacillus subtilis and pseudomonas fluorescens. Accordingly, in the tobacco seedling raising stage and after transplantation, the mixed bacteria agent of the bacillus subtilis and the pseudomonas fluorescens is applied, diseases such as blackleg and bacterial wilt of the tobacco can be effectively controlled through different application time and application methods,and the tobacco incidence is lowered.

Description

technical field [0001] The invention relates to the technical field of tobacco planting, in particular to a method for preventing and treating tobacco diseases. Background technique [0002] Black shank and bacterial wilt are two devastating diseases in tobacco production, which generally occur before and after topping of tobacco plants, resulting in serious losses for tobacco farmers. At present, thiophanate-methyl WP or chlorothalonil WP are mainly used for the prevention and treatment of black shank, and streptomycin sulfate or copper ammonia water are mainly used for the prevention and treatment of bacterial wilt. However, the control effect of these chemical agents is not good, and the incidence of tobacco black shank and bacterial wilt is still high. [0003] In view of this, the present invention is proposed. Contents of the invention [0004] The present invention relates to a kind of prevention and treatment method of tobacco disease, comprising the following st...
