Abstract
The study was conducted to obtain the basic information on the diseases epidemics of vegetable crops grown in Namji, Jinju, Gimhae and Suncheon under the extremely varied and specified conditions, plastic film house. The disease survey was conducted from the end of April, 1951 to April 1982. Leaf mold and late blight were serious foliar disease in tomato during the seedling stage, especially when the infected seeds were sown. The diseases increased rapidly 35 days after seeding. In both continuous cultivation of cucumber and rotation with upland crops, incidence of Fusarium wilt was severe while incidence of the disease was negligible in cultivations after paddy rice or grafting on pumpkin. Downy mildew of cucumber was severe in Jinju and Suncheon area, however, it was not so serious in Namji area where the growing season of cucumber was unfavorable for the maximum disease incidence. Cucumber mosaic virus disease was prevalent in the areas surveyed and the disease incidence was increased rapidly after June. Powdery mildew prevailed at the early stage of cucumber growth after transplanting in Namji area. Root rot and wilting caused by Phytophthora capsici was as the most destructive disease in pepper grown under the vinyl house, especially in Namji and Jinju area where the pepper has been cultivated intensively. The Phytophthora attacked most parts of young plants during the winter time and then induced crown rot on the adults plants. Cultivation of pepper in vinyl house was almost impossible because of the Phytophora disease by the end of June. Virus diseases to tomato plants were prevalent throughout the surveyed area and the damage was also severe. In Jinju and Gimhae area leaf mold and late blight showed high infection rate in tomato during the harvest time.
남부시설원예지대의 중심을 이루고 있는 김해 남지 진주 순천 등 4개지역을 대상으로 1981년 4월말부터 1982년 4월말까지 비닐하우스에서 재배되고 있는 주요채소에 발생되는 병의 종류와 발생율, 전염경로, 발병환경 등을 작물별 생육기별로 조사하여 다음과 같은 결과를 얻었다. 토마토의 잎곰팡이병과 겹둥근무늬병은 유묘류에 가장 피해를 주는 병으로 이병 종자를 파종한 경우는 파종후 35일부터 급격히 병세가 진전되였다. 오이의 덩굴쪼김병은 접목재배나 답전환 윤작재배시는 발병주율이
