Salts 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 کاملControl of potato early blight with triazole fungicide using preventive and curative spraying, or a forecasting system
J.D. Mantecón. 2009. Control of potato early blight with triazole fungicide using preventive and curative spraying, or a forecasting system. Cien. Inv. Agr. 36(2):291-296. During the 2005 and 2006 growing seasons, two fi eld trials were conducted at the INTA Balcarce Experimental Station (Argentina) to study the control of potato early blight (Alternaria solani). Uncut virus-free seed tubers of...
متن کاملPotato blight and anencephalus in Scotland.
The theory has recently been put forward by Renwick (1972a) that anencephalus and spina bifida are caused by exposure early in pregnancy to potatoes which are affected by blight or are imperfect for other reasons. In support of this, a temporal correlation was claimed to exist between the severity of blight and the frequency of anencephalus, largely because of a strong correlation between the a...
متن کاملEffect of Some Essential Oils for Limiting Early Blight (alternaria Solani) Development in Potato Field
The fungicidal effect of some essential oils against Alternaria solani one of the species that cause early blight of potato was evaluated under in vitro and field conditions. Effect of carnation, caraway, thyme oils and the chemical fungicide Ridomil MZ 72 at various concentrations on mycelial growth of A. solani was tested. Carnation oil had the strongest and most extensive inhibitory effect o...
متن کاملA test of taxonomic predictivity: resistance to early blight in wild relatives of cultivated potato.
Host plant resistance offers an attractive method of control for early blight (caused by the foliar fungus Alternaria solani), a widespread disease that appears annually in potato crops worldwide. We tested the assumed ability of taxonomy to predict the presence of early blight resistance genes in wild Solanum species for which resistance was observed in related species. We also tested associat...
