Abstract

The year of 2003 was characterized as a cool humid year. Low temperature and frequent rains were continued during March to July, resulting in 1.6 times higher rainfalls and 32％ less sunshine period compared to the average yean Due to 2003's climatic condition, rice blast, and bacterial leaf blight occurred severely. Higher rainfalls caused severe epidemic of phytophthora disease and, in case of red-pepper, 55％ of cultivation acreage was devastated by the disease over the country. Besides, crop diseases which become severe under cool-humid conditions, such as gray mold, sclerotinia rot, downy mildew, increased significantly compared to the previous year. In fruit trees, brown spot of apple, and pear scab occurred severely causing much yield loss.

2003년은 냉해의 해였다. 3월부터 7월까지 저온이 지속되었고 생육기 내내 비가 자주 내려 강수량은 평년의 1.6배 일조시간은 평년의 68％ 수준이었다. 이 때문에 벼도 열병, 흰잎마름병이 심하게 발생하였고 강우에 의해 전반되는 역병이 대발생하여 고추의 경우 전국 재배면적의 55％가 피해를 입었다. 이외에 저온다습 조건에서 발생이 많은 잿빛곰팡이병 균핵병, 노균병이 전년에 비해 크게 증가하였고 과수의 경우 사과갈색무늬병, 배검은별무늬병이 대발생하여 큰 피해를 가져왔다.
