Zusammenfassung: | This study was carried out to develop the economic thresholds for the control of bacterial spot of red pepper. The correlation between diseased leaf rate and yield in field was Y=-0.724X+281.58, $R^2=0.78$, $r=-0.88^{**}$. The correlation between diseased leaf rate and yield loss in field was Y=0.813X+15.95, $R^2=0.78$, $r=0.88^*$.We found that control thresholds was below 30.3% diseased leaves rate per plant in field. The economic control thresholds for bacterial spot of red pepper was below 16.3%. 고추 세균점무늬병이 수량에 미치는 영향을 조사하여 경제적 방제수준을 설정하고자 시험을 수행하였다. 노지고추 세균점무늬병 발생정도와 수량과의 회귀식은 Y=-0.724X+281.58, $R^2=0.78$, $r=-0.88^{**}$ 성립하였다. 노지고추 세균점무늬병 발생정도와 수량감소와의 회귀식은 Y=0.813X+15.95, $R^2=0.78$, $r=0.88^{**}$ 성립하였다. 성립된 회귀식을 이용하여 노지 고추 수량에 영향을 주지 않는 수준의 세균점무늬병 방제적기는 발생 발병엽률이 30.3% 이하이었다. 또한 고추 세균점무늬병 경제적 방제수준은 노지 고추 세균점무늬병 발생정도가 16.3% 이하로 결정되었다. |
