Abstract

Wildfire caused by Pseudomonas amygdali pv. tabaci has been seen a steady increase in the incidence and prevalence on soybean in Korea. But up to know there is no official report on the prevalence of the disease in Korea. The nationwide survey of the occurrence of soybean wildfire showed that 19 out of 30 regions in 2014 and 9 out of 28 regions in 2015 had been infected with P. amygdali pv. tabaci. The severity of wildfire varied according to the cultivar, cultivation regions and climates. However, cultivar seoeitae was susceptible in both 2014 and 2015. The disease severity of 2014 was twice that of 2015. Since the temperature of 2014 and 2015 were very similar but the precipitation of 2014 was more than twice that of 2015, the precipitation of 2014 had a great impact on the wildfire disease severity.

들불병은 콩의 주요 세균병 중 하나로 국내 콩 주요 재배지에서 꾸준히 발생되고 있지만 지금까지 발생 정도에 대한 보고가 없었다. 국내 콩 주요 재배지에서 들불병 발병 정도를 2014년과 2015년 2년간 조사하였다. 2014년 전국 조사에서는 조사한 30지역 중 19지역(수원, 영월, 괴산, 단양, 태안, 공주, 부여, 김제, 순창, 고창, 무안, 장흥, 안동, 청도, 칠곡, 경주, 예천, 영천, 합천)에서 들불병 발생을 확인하였으며, 2015년 전국 조사에서는 조사한 28지역 중 9지역(수원, 영월, 평창, 인제, 괴산, 단양, 충주, 무안, 안동)에서 들불병 발생을 확인하였다. 재배되고 있는 품종, 지역, 기후 조건에 따라 들불병 발병 차이가 났다. 서리태는 2014년과 2015년 모두 감수성을 보였으며 강수량이 많았던 2014년에 들불병의 발생이 2배 이상 증가하였음을 관찰할 수 있었다. 본 실험 결과 우리나라는 전국적으로 들블병균이 잠재해 있으며 비슷한 온도에서는 강수량이 들불병의 발생에 절대적인 영향을 준다는 것을 알 수 있었다.
