Abstract

Major diseases and insect pests in nursery season of strawberry were anthracnose, powdery mildew, Fusarium wilt, two-spotted spider mite, and aphids. Environmental-friendly and chemical application schedules can improve diseases and insect pests control with relatively fewer organic and chemical materials inputs compared with spray programs when it's occurred. Field experiments were performed in 2012 to 2013 according to calendar-based spray programs with environmental-friendly spray calendar (EFSC) and conventional chemical spray calendar (CSC) for controlling diseases and insect pests of strawberry plants cv, Seolhyang during the two nursery seasons. EFSC did reduce the incidence of diseases and insect pests as compared to the non-treated control. Incidence of anthracnose and powdery mildew by EFSC and CSC was similar in 2012 and 2013 seasons. In addition, occurrence of two-spotted spider mite in EFSC in 2013 was similar to those of CSC and was shown highly in early and mid-June both 2012 and 2013 seasons. Occurrence of aphid in EFSC was shown highly in early and mid-June both 2012 and 2013 seasons. These results suggest that EFSC program may be effective for controlling strawberry diseases and insect pests by using environmental-friendly organic materials.

딸기 육묘기에 발생하는 주요 병해충은 탄저병, 흰가루병, 시들음병, 점박이응애, 진딧물 등이 있다. 친환경과 약제 처리 방제력은 병해충이 발생할 때 처리하는 방제프로그램과 비교하여 적은 유기농업자재와 살균 살충제 사용량으로 병해충방제 효과를 높일 수 있다. 2012년과 2013년 딸기 육묘기에 설향 품종을 대상으로 병해충 방제를 위한 친환경 방제력(EFSC)과 약제 방제력(CSC)효과 시험을 실시하였다. EFSC는 육묘기간 동안 무처리 대비 병해충 발생이 감소되었다. 탄저병과 흰가루병 발생은 EFSC와 CSC처리에서 2012년과 2013년 시험동안 비슷한 이병율을 보였다. 점박이응애 발생은 2013년에 EFSC와 CSC처리간 비슷하였고 6월 중순에 높은 피해율을 보였다. 진딧물 발생은 EFSC에서 6월 초중순에 높은 발생율을 보였다. 이러한 결과로 EFSC처리는 친환경으로 딸기에 발생하는 병해충을 효과적으로 방제하는 데 CSC를 대체할 수 있을 정도로 도움을 줄 수 있을 것이다.
