Abstract:

In order to ensure the safe production of tobacco, the registered pesticides of bacterial diseases such as tobacco bacterial wilt, wildfire and angular leaf spot (as of September 7th, 2024) and related pesticides in research reports were statistically analyzed. The results showed that there were 16, 52 and 3 registered pesticide products for the control of bacterial wilt, wildfire and angular leaf spot, respectively. There were 14, 20 and 2 registered pesticide active ingredients for bacterial wilt, wildfire and angular leaf spot, respectively. There was no registered pesticide to control flag leaf disease and hollow stem disease of tobacco. There were 9 formulations and 3 toxicities in registered pesticide products, among which wettable powder and low toxic pesticides account for the highest proportion. It is necessary to choose and use low-toxic and environmentally-friendly pesticides scientifically and legally, according to the law of incidence in the process of tobacco production. Pesticide enterprises can further accelerate the progress of pesticide registration of bacterial diseases such as tobacco angular leaf spot, flag leaf disease and hollow stem disease, and provide reference for scientific pesticide prevention and control of tobacco bacterial diseases.

Key words: tobacco, bacterial diseases, registered pesticides
