Zusammenfassung:This study was carried out to develop control thresholds for anthracnose on red pepper. To investigate relationship between anthracnose incidence and diseased fruits, experimental plots with six treatments were established. There existed close correlation between rate of diseased fruits and yields in field (Y = -16.83X + 327.57, $R^2=0.83$), in rain shelter (Y = -4.92X + 361.02, $R^2=0.84$), and in rain shelter with rain (Y = -5.91X + 359.71, $R^2=0.76$). Control thresholds for anthracnose of pepper were 0.9% diseased fruits per plant in field and from 1.7 to 2.3% diseased fruits rate per plant in rain shelter. 고추 탄저병 요방제 수준을 설정하기 이하여 시험한 결과 노지 고추 수량에 영향을 주지 않는 수준의 탄저병 방제적기는 발생정도가 0.9% 이하이었으며, 노지고추 탄저병 발생정도와 수량과의 회귀식은 Y = -16.83X + 327.57, $R^2=0.83$ 성립하였다. 비가림 재배(무강우 조건) 고추의 수량에 영향을 주지 않는 수준의 탄저병 방제적기는 발생정도가 1.7% 이하이었으며, 고추탄저병 발생정도와 수량과의 회귀식은 Y = -4.92X + 361.02, $R^2=0.84$ 성립하였다. 비가림 재배(강우 조건) 고추의 수량에 영향을 주지 않는 수준의 탄저병 방제적기는 발생정도가 2.3% 이하이었으며, 고추 탄저병 발생정도와 수량과의 회귀식은 Y =-5.91X + 359.71, $R^2=0.76$ 성립하였다.
