| Tobacco is an important economic crop in China, and pest control is the main problem to be solved in the process of planting. At present, tobacco diseases and pests mainly include Spodoptera litura, Heliothis assulta, Myzus persicae, Agrotis ypsilon, Phytophtora parasitica var. nicotianae, virus disease, Alternaria alternata, Colletorichum lagenarium and Ralstonia solanacearum etc. There were still some problems on the aspect of tobacco pest control, such as the use of high-toxic chemical agents, single pesticide variety, and bias to traditional formulation, which leaded to high pest resistance and excessive pesticide residues. Moreover, tobacco or other rotation crops were harmed by improper use of chemical agents, which affected soil properties and agricultural production seriously. Therefore, it is urgent to select safe and effective pesticides to control tobacco diseases and diseases and pests. In order to preliminarily understand the current status of registered pesticides for controlling major tobacco diseases and pests, the registration status and existing problems of pesticides for controlling major tobacco diseases and pests were summarized and analyzed. The registration of pesticides as
of December 7, 2020 in China was used for analysis and was compared with that of the pesticides used for the same kinds of pests on other crops. The result could provide countermeasures for the registration of pesticides in the future, and improve the technical level of rational use of pesticides in the control of diseases and pests on tobacco. |
