Abstract

From our field investigation from 2017 to 2018, five diseases and four insect pests have been identified as the primary biotic stressors of fruit-producing mulberry, which include popcorn disease and mulberry sucker, respectively. In this study, we examined the relative control effects of selected agro-chemicals against the popcorn disease and mulberry sucker. Our systemic treatment methods to simultaneously control the popcorn disease and the mulberry sucker indicated that an integrated control method showed a superior result with the control efficacy of 89.3%, while a conventional control method resulted in 66.7%. As a result, we concluded that it is much efficient to control both disease and insect pest in mid-April while sequentially applying chemicals only for the popcorn disease from February. By considering the ecological aspects of the popcorn disease and mulberry sucker, this systemic treatment will be able to reduce the labor of growers required for the control.

2017년도에서 2018년도까지 오디 생산용 뽕나무에 발생하는 주요 병해충 발생양상을 조사하였다. 병은 균핵병 등 5종, 해충은 뽕나무이 등 4종이 수확 전에 피해를 주는 것으로 조사되었다. 본 연구에서는 가장 큰 문제를 일으키는 균핵병과 뽕나무이에 의한 피해를 예방하기 위해 약제 체계별 방제효과를 조사하였다. 균핵병과 뽕나무이를 동시에 방제하기 위한 체계처리 결과는 관행방제구의 방제효과가 66.7%이었던 반면 종합방제구는 89.3%로 방제효과가 우수하였다. 실험 결과를 바탕으로 균핵병 예방을 위해 2월부터 순차적으로 약제를 처리하면서 4월 중하순에 균핵병과 뽕나무이를 동시방제하는 것이 방제에 필요한 노동력도 경감하고 병해충 발생생태에 맞춘 방제방법으로 오디 생산 현장에서 활용도가 높을 것으로 생각된다.
