Application of interactive application of exogenous selenium and exogenous molybdenum in resisting phytophthora nicotianae

The invention relates to application of exogenous selenium and exogenous molybdenum in resisting phytophthora nicotianae through interactive application, and relates to the technical field of pesticides. According to the method, exogenous selenium and molybdenum are applied to the soil, so that the black shank resistance of the tobacco can be improved, the growth and development of tobacco seedlings can be promoted, the stress resistance is improved, the dual effects of promoting the growth and development of tobacco plants and improving the black shank resistance of the tobacco at the same time are achieved, and the method has great significance in preventing and treating the tobacco black shank. 本发明涉及一种外源硒与外源钼交互施用在抗烟草疫霉中的应用，涉及农药技术领域。本发明向土壤中施加外源硒和钼，不仅能提高烟草抗黑胫病的能力，还能促进烟草幼苗的生长发育、提高抗逆性，发挥同时促进烟草植株生长发育和提高烟草抗黑胫病能力的双重功效，对防治烟草黑胫病具有重大意义。
