马铃薯晚疫病(Potato Late Blight) 农业植物病理学 课件 马铃薯晚疫病(PotatoLateBlight)马铃薯晚疫病又称疫病、马铃薯瘟,是一种导致马铃薯茎叶死亡和块茎腐烂的毁灭性病害。在多雨、冷凉、适于晚疫病流行的地区和年份,植株提前枯死,损失20%-40%。曾引起爱尔兰饥饿,导致约100万人死亡。马铃薯晚疫病 马铃薯晚疫病-...
can become airborne and quickly and widely disseminated within a region during cloudy and wet weather and, when disease-favoring weather of mild temperatures and rainy conditions occur, they usually prevail over the entire region. As a result, late blight in a field can quickly spread to ...
A method for rapid cloning of plant disease-resistance genes could provide sustainable genetic solutions to crop pests and pathogens in place of agrichemicals. Global yields of potato and tomato crops have fallen owing to potato late blight disease, whic

Late blight caused by Phytophthora infestans is one of the main diseases in potato production. The Netherlands has a high potato density and favourable weather conditions for the disease, and this combination leads to frequent outbreaks of late blight. A spatially explicit agent-based model of the...
A polymerase chain reaction (PCR)-based test for potato late blight (Phytophthora infestans) and pink rot (P. erythroseptica, P. nicotianae) diseases has been developed for use with potato tuber tissue. Primers based on sequence analysis of the ITS2 region of ribosomal DNA of late blight and...
infestans. However, most of the build-up of disease results from the asexual reproductive cycle that consists of spore germination, infection of foliage, colonisation of foliage, sporulation, and spore dispersal and survival. The different stages in the asexual cycle of reproduction are affected by ...
