  • Soilborne diseases pose a serious problem for mulberry cultivation during nursery plantation and established gardens, which cause severe loss in revenue generation of mulberry growers as compared to foliar diseases. Various soilborne diseases affect mulberry. Among them, root knot and root rot affect the established plantation resulting in severe loss in leaf yield apart from deterioration in leaf quality, which is a pre-requisite in successful sericulture to get the good quality of cocoons. Besides, stem-canker, cutting rot, collar rot and die-back, affect the initial establishment and survivability of mulberry plantation in nursery. The problem is difficult to handle, due to the complex nature of the diseases and also involvement of various biotic and abiotic factors. This is compounded by the occurrence of disease complex (especially nematode + soilborne pathogenic microbes) in established mulberry gardens, which facilitates quick spread of the disease and enhance the plant mortality, resulting substantial loss in leaf yield. Therefore, prevention and timely control measures need to be taken up to protect the mulberry plants from different soilborne plant pathogens. In this review article, symptomatology, epidemiology, disease cycle and control measures of soilborne diseases of mulberry are discussed.

  • 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.

  • Lysobacter antibiocus HS124 is a chitinase-producing rhizobacterium with proven capacities to suppress plant diseases. Bacterial cultures of L. antibioticus HS124 showed strong biocontrol efficacies against various plant diseases compared to those of bacterial cultures of Bacillus subtilis QST713 which is an active ingredient of a commercial biopesticide, Serenade. Here, we report the draft genome sequence and automated annotation of strain HS124. This draft genome sequence indicates the novelty of L. antibiocus HS124 and a subset of gene functions that may be related to its biocontrol activities.
