과수화상병 방제를 위해 수간주입한 옥솔린산의 잔류특성

Abstract

Fire blight is a pathogen that is prohibited from being introduced, such as causing the entire tree to wither. It is virtually impossible to completely eradicate and treat it once it breaks out. Therefore, because it causes economic and psychological losses to farms, this study was conducted to develop more effective pesticide by supplementing the pesticides that have been previously used. oxolinic acid (10%) SL, which is effective in controlling pathogens, was selected as the target pesticide. The spraying method was changed to a method that has a more direct effect, and the apple and pear trees were trunk-injected right before flowering. samples were collected and the pretreatment method and instrumental analysis method were established. Based on the analysis results, there was a possibility of developing a new pesticide even within the limited experimental method. However, it is difficult to apply it to commercial orchards, so further review is necessary.
