Effect of Host Plant Resistance and Reduced Rates and Frequencies of Fungicide Application to Control Potato Late Blight
Late blight of potato (Solanum tuberosum, L.) caused by Phytophthora infestans (Mont.) de Bary, is a major worldwide threat to the production of high quality potatoes (12). Unchecked, P. infestans can rapidly defoliate plants in the field and can infect potato tubers when spores are washed into the soil (15). Prior to the early 1990s, the population of P. infestans throughout much of the world ...
متن کاملSalts Application for Suppressing Potato Early Blight Disease
The suppressive effect of sodium and calcium salts applied individually or combined with the yeast Saccharomyces cerevisiae against Alternaria solani the causal agent of early blight disease of potato was evaluated under laboratory, greenhouse and field conditions. In vitro test a complete inhibition in fungal growth was observed at concentration of 30 mg/ml of both sodium bicarbonate and calci...
متن کاملThe early days of late blight
Large-scale DNA sequencing of samples of foliage collected in the 19th century from plants infected with late blight has shown that the potato famines of the 1840s were triggered by a single clonal lineage of Phytophthora infestans, called HERB-1, which persisted for at least 50 years.
متن کاملEvaluation of potato late blight management utilizing host plant resistance and reduced rates and frequencies of fungicide applications
Field experiments were carried out (2001–2003) to evaluate the efficacy of combining host resistance with reduced rates and frequencies of the residual contact fungicide fluazinam to control foliar potato late blight (Phytophthora infestans). Potato cultivars (cvs.) and advanced breeding lines (ABL) developed in four states were used in combination with fluazinam applications at 0, 33%, 50%, 66...
