Abstract

This study was conducted for 3 years in an apple orchard to investigate the efficacy of the glufosinate-ammonium (GFA) SL for weed control in comparison to non-woven fabric mulch, sod culture and machinery cutting treatments. Glufosinate-ammonium SL 18% was applied with 2 to 3 times, and the extents of injury caused by the different weed control methods were also investigated during the 3 years. The highest level of weed control was obtained by glufosinate-ammonium 3 times spray (98.7%), followed by machinery cutting (95.1%), glufosinate-ammonium 2 times spray (81.5%) and natural sod culture (5.8%). Amounts of fruit production in three times application of glufosinate-ammonium 540 g a.i. $ha^{-1}$, twice application of GFA, machinery cutting, non-woven fabric processing, sod culture and untreated control were 27.2, 26.2, 25.3, 24.1, 20.4 and 13.3 kg, respectively. There was no toxicity symptom of glufosinate-ammonium on the whole tree such as fruit, bud, trunk, branch and flower during the 3 years.

사과원에서 잡초방제 방법에 따라 제초효과 및 과실 생산량, 약해 발생 정도를 조사하였다. 시험처리는 부직포피복구, 초생재배구, 기계제초구, 제초제(GFA, Glufosinate ammonium SL 18%) 2회 및 3회 처리구와 무처리구를 두어 2001년부터 2013년까지 3년간 반복실험하였다. 시험 결과 처리별 방제효과는 부직포피복 처리구가 가장 높았으며, GFA 3회 처리 98.7%, 기계예초 95.1%, GFA 2회 처리 81.5%, 초생재배 5.8% 순이었다. 잡초방제 방법에 따라 과실 생산량은 GFA 3회 처리 27.2 Kg으로 시험구 중 생산량이 가장 많았으며, GFA 2회 처리 26.2 Kg, 기계제초구 25.3 Kg, 부직포피복구 24.1 Kg, 초생재배구 20.4 Kg, 무처리 13.3 Kg 순이었으며, 모든 처리구에서 잎, 과실에서 약해 발생은 없었다.
