Abstract

Incidence of Phytophthora blight of hot pepper (Capsicum annuum) and yield (fresh weight) of pepper fruits were investigated at four separate fields located in Cheongwon, Boeun, Eumsung, and Goesan, which are major pepper production areas in Chungcheongbuk-Do. In all of the experimental fields except the Goesan field, increased incidence of Phytophthora blight led to decreased yield of pepper fruits. The harvest time in which the yield of red pepper fruits was highly correlated with the incidence of Phytophthora blight was different between areas: it was highly correlated in the third harvest in Cheongwon (y=-11.0x+435.2, $r^2$=0.99), but in the second harvest in Boeun (y=-15.0x+944.6, $r^2$=0.76). In contrast, there was a very low correlation between the pepper yield and the disease incidence in Goesan in which pepper seedlings grafted on resistant stocks were planted. The final disease incidence in the Cheongwon experimental field reached 100% more than 40 days later in 2007 compared with that in 2006. The control threshold of Phytophthora blight in the pepper fields where disease incidence had been lower than 5% was set as 0.8% disease incidence, which caused less than 5% yield loss.

충북의 고추 주산지인 청원, 보은, 음성, 괴산의 포장에서 고추 역병 발생에 따른 이병주율과 수량과의 관계를 조사하였다. 괴산을 제외한 3개의 시험포장에서 고추 역병의 증가는 수량감소를 가져왔다. 고추 역병 이병주율과 수량 사이의 높은 상관을 나타내는 수확시기는 청원에서는 3차, 보은에서는 2차 수확기로 나타나 지역별로 다소 차이를 보였다. 이와는 달리 저항성 대목을 이용하여 접목재배를 한 괴산 시험포장에서는 고추 역병 발생량과 수량 사이에 매우 낮은 상관을 나타냈다. 청원 시험 포장에서 이병주율 100%에 도달하는 데 소요되는 시기는 2006년에 비해 2007년에 40일 이상 늦어졌다. 고추 역병 발생이 적었던 포장(이병주율 5% 이하)에서 수량감소 5%를 가져오는 고추 역병 요방제 수준은 0.8%로 설정되었다.
