Evaluation of treatment strategies of the late blight Phytophthora infestans in Nepal by population dynamics modelling
The late blight disease caused by the fungus Phytophthora infestans is a serious pest of solanaceous crops capable of destroying a complete harvest. Therefore it is heavily treated with fungicides, especially in areas where the knowledge among farmers about application and impacts of fungicides is generally low, as it is the case in Nepal. In order to derive efficient treatment strategies with ...
متن کاملCharacterization of the Potato Late Blight Pathogen Phytophthora infestans in Tunisia
This mini-review focus on summarizing different phenotypic and genotypic analysis recorded on Phytophthora infestans population collected from the Northern area of Tunisia. Here, we demonstrated that mating type distribution plays a primordial role in genetic structure of the pathogen between sampling regions. Also, a probably strong correlation between mating type and metalaxyl resistance coul...
متن کاملPlant-mediated gene silencing restricts growth of the potato late blight pathogen Phytophthora infestans
Phytophthora infestans is an oomycete that causes severe damage to potato, and is well known for its ability to evolve rapidly in order to overcome resistant potato varieties. An RNA silencing strategy was evaluated here to clarify if small interfering RNA homologous to selected genes in P. infestans could be targeted from the plant host to reduce the magnitude of the infection. As a proof-of-c...
متن کاملHistoric Late Blight Outbreaks Caused by a Widespread Dominant Lineage of Phytophthora infestans (Mont.) de Bary
Phytophthora infestans (Mont.) de Bary, the causal agent of potato late blight, was responsible for the Irish potato famine of the 1840s. Initial disease outbreaks occurred in the US in 1843, two years prior to European outbreaks. We examined the evolutionary relationships and source of the 19th-century outbreaks using herbarium specimens of P. infestans from historic (1846-1970) and more recen...
متن کاملLoop-mediated isothermal amplification for detection of the tomato and potato late blight pathogen, Phytophthora infestans.
AIMS To design and validate a colorimetric loop-mediated isothermal amplification assay for rapid detection of Phytophthora infestans DNA. METHODS AND RESULTS Two sets of loop-mediated isothermal amplification (LAMP) primers were designed and evaluated for their sensitivity and specificity for P. infestans. ITSII primers targeted a portion of the internal transcribed spacer region of ribosoma...
