摘要：
The present invention relates to a composition for controlling pine wilt disease comprising acibenzolar-S-methyl as an effective component and a method for controlling pine wilt disease using the composition. It was verified by the present invention that the disease control efficacy of acibenzolar-S-methyl against pine wilt disease was due to the resistance induced by acibenzolar-S-methyl in pine trees by in vitro determination and in vivo pathogenesis assay. The resistance in pine by acibenzolar-S-methyl has similar characteristics of general induced resistance in other plants that induced resistance elicitors are induced effectively by application with a small amount and the expression of a specific defense related genes is increased. Thus, the resistance in pine by acibenzolar-S-methyl is considered to have no adverse effect on the human health and no environmental problem. On the basis of the results of this invention, it is possible to develop an eco-friendly chemical formulation for the management of pine wilt disease, and, by taking advantage of the induced resistance, there is high potential to develop a new-concept controlling agent for the control of pine wilt disease. In addition, the trunk injection method of a nematicidal agent, which is conventionally used to control the pine wilt disease, can be replaced by soil drenching or foliar spraying of the induced resistance formulation. Especially, soil drenching or foliar spraying of acibenzolar-S-methyl formulation have many advantages in that it is able to control effectively pine wilt disease at low cost and its application range for the management of pine wilt disease can be extended up to even forests or areas that are inaccessible to human.
