Xanthomonas campestrispv.campestrisin Western Washington Crucifer Seed Fields: Occurrence and Survival

Persistence of Xanthomonas campestris pv. campestris in Field Soil in Central Europe

“…There have been a number of other studies that have examined the survival of Xcc in the soil environment. Most studies have focused on survival in association with crop debris and it has been well established that Xcc can potentially survive in brassica crop debris in soil as long as the debris remains visibly present (up to two years in the case of tough stem residues) [ 9 , 11 , 12 , 13 , 14 , 15 ]. On the other hand, when planktonic Xcc has been added to soil, survival time has been relatively short, e.g., up to six weeks in winter [ 9 ] and less at warmer temperatures.…”

“…Various studies have been made regarding the persistence of Xcc in soil, but most of them have focused on survival in association with crop debris. Thus it has been well established that Xcc can potentially survive in brassica crop debris in soil as long as debris remains visibly present [ 9 , 11 , 12 , 13 , 14 , 15 ]. On the other hand, Schaad & White [ 9 ] suggests that Xcc cannot survive in soil for more than 42 days in winter and 14 days in summer without the host plant debris.…”

“…배추과 작물의 검은썩음병을 방제하기 위하여 윤작을 하거나 종자에 물리화학적 처리를 하여 제조한 무균 종자를 재배하는 것이 비교적 효과적이다 (Gangopadhyay and Gill, 1977;McKeen, 1981;Kishun, 1984;Schultz and Gabrielson, 1986;Schaad and Alvarez, 1993). 또한 보르도액과 항생제 등을 이용한 화학적 방제 (Knosel, 1965;Onsando, 1988;Gupta, 1991;Bhat et al, 2000), 길항미생물 Bacillus 균주 배양액을 이용한 생물학적 방제 즉, 식물체의 뿌리를 미생물 배양액에 침지한 후 이식하거나, 배양액을 종자에 침지하여 파종하기 및 배양액을 엽면에 살포하여 검은썩음병을 방제하는 연구가 진행되고 있다 (Jalali and Parashar, 1995;Pichard and Thouvenot, 1999;Wulff et al, 2002).…”
