Abstract
In 2005, average temperature was lower, and average rainfall was less than those of previous year. The diseases of rice, barley, pepper, chinese melon, apple and oriental pear were surveyed. Bacterial blight, bacterial grain rot, and panicle disease of rice, black rot of pear, and white rot and bitter rot of apple were severe. Especially, brown rot of rice occurred four times higher than those of previous year. Panicle blight of rice increased about 3 times, compared with the previous year, presumed that the higher rainy days, rainfall and RH promoted spread of the fungal pathogens to panicles of rice. The diseases of rice leaf blast, sudden wilt syndrome, downy mildew and powdery mildew of chinese melon in plastic greenhouse, and virus diseases of hot pepper occurred distinctly less than those of the previous year. Another diseases surveyed occurred similar or less.
2005년은 전년에 비해 기온이 낮았고 강수량이 적었다. 벼 흰잎마름병, 세균성벼알마름병, 벼 깨씨무늬병, 벼 이삭도열병, 배나무 겹무늬병 등이 2004년에 비해 증가하였다. 특히 벼 깨씨무늬병은 전년에 비해 4배 이상 병 발생이 증가하였다. 벼 이삭도열병이 전년 0.7%에서 2005년 2%로 증가된 것은 출수기 동안 평균기온은 높았고 강수일수, 강수량 및 습도가 높아 잎도열병균이 이삭으로의 전파를 촉진한 것으로 추정되었다. 기타 조사된 병들은 전년에 비해 감소 혹은 유사한 수준이었다. 벼 잎도열병, 시설참외 시들음증상, 흰가루병 및 노균병은 전년에 비해 크게 감소되었다.
