Abstract

Abstract:

In recent years, tobacco diseases and pests have occurred in numerous types with severe damage, significantly affecting the yield and quality of tobacco. The long-term irrational use of chemical pesticides has triggered a series of issues such as excessive pesticide residues, intensified environmental pollution, and endangering human health. In order to reduce the adverse impacts of chemical pesticides and develop green and efficient strategies for tobacco disease and pest control, this paper systematically summarizes the conventional control strategies and biological control strategies of tobacco pests and diseases, focusing on elaborating the latest research progress of new prevention and control strategies such as botanical pesticides, natural enemy insects, microbial preparations, RNA pesticides and nano-delivery technology. The results showed that: (1) in the traditional biological control, Trichoderma and Arma chinensis had significant control effects on tobacco black shank and Myzus persicae (the control effect was more than 60%). (2) RNA pesticides achieve precise prevention and control by specifically silencing target genes, and nano-delivery technology can improve their stability and delivery efficiency. (3) The new prevention and control strategy has the advantages of environmental friendliness and target specificity, but there are problems such as high cost and insufficient field stability. In summary, biological control technology is the core direction of green prevention and control of tobacco diseases and pests. Traditional biological control and new RNA pesticides have their own application value. In the future, it is necessary to deepen the research on prevention and control mechanism, promote technology integration innovation, optimize RNA pesticide and nano-delivery technology, and provide more comprehensive technical support for tobacco green production.

Key words: tobacco pests and diseases, control strategy, conventional control strategy, biological control strategy, RNA pesticides, nano-pesticides
