Composition for controlling pine wilt disease comprising methyl salicylate or its derivative as effective component and method for controlling pine wilt disease using the same

摘要

The present invention relates to a composition for controlling pine nutrient disease comprising methyl salicylate, a derivative thereof or an agrochemically acceptable salt thereof as an active ingredient, and a method for controlling pine reemergence using the composition, The inhibitory effect of salicylate was confirmed by induction resistance in vitro . Induced resistance is generally effective in small amounts, and it is harmless to the human body and does not cause environmental pollution because it shows the effect of gene expression in plants. Therefore, it is possible to develop environmentally friendly medicines for pine wilt disease, and it is highly possible to develop a novel concept of pine wilt disease control agent. In addition, it is possible to effectively control the injection method of the nematode formulation used for controlling the existing pine wilt disease, at a lower cost than that of the induction-resistant formulation when it is converted into a soil-rooting or leaf-surface spraying method, and application of the pine tree- It has the advantage of broadening the range.
