Abstract

Pear scab and rust are the major diseases causing severe epidemics in organic cultivation of pear trees. Incidences of pear scab and rust were compared in organically managed plots and conventionally managed plots to obtain optimum application schedule of environment-friendly control agents in organically managed plots. Organically cultural practice with 10 time-applications of lime sulfur and Bordeaux mixture showed higher than 40% of control efficacies of pear scab and rust compared to conventionally cultural practice. Organically cultural practice with 8 time-applications of lime sulfur considering weather condition showed higher than 30% of control efficacies of pear scab compared to conventionally cultural practice. The results suggest that proper application of environment-friendly control agents such as lime sulfur considering weather condition will enable effective control of the major diseases for organic cultivation of pear.

배를 유기재배하는 과원에서 문제가 되는 주요 병을 효과적으로 방제할 수 있는 친환경유기농자재 살포프로그램을 도출하기 위하여 친환경유기농자재 살포에 따른 검은별무늬병과 붉은별무늬병에 대한 방제효과를 관행재배와 비교 검정하였다. 석회유황합제와 석회보르도액을 10회 살포한 친환경방제구에서는 관행재배과원에 비해서 잎에 발생하는 검은별무늬병과 붉은별무늬병에 대해 40% 이상의 방제효과를 증대시켰다. 석회유황합제만을 기상조건을 고려하여 강우 전후에 8회 살포한 친환경방제구에서도 관행재배과원에 비해서 과실에 발생하는 검은별무늬병에 대해 30% 이상의 방제효과를 증대시켰다. 배 유기재배시 기상조건을 고려하여 친환경유기농자재 살포시기를 조절하는 친환경방제로 주요 병의 효율적 관리가 가능하리라 전망된다.
