Botanicals and Phosphonate Show Potential to Replace Copper for Control of Potato Late Blight
Potato late blight (PLB) caused by Phytophthora infestans (Pi) is the most harmful disease in potato production worldwide. In organic farming, copper is used despite its persistence in soil and toxicity to soil organisms. To replace copper, suspensions of powders from three promising botanicals, including bark of buckthorn (Frangula alnus, FA), roots of medicinal rhubarb (Rheum palmatum) and ga...
متن کاملEvaluation of innovative products to reduce copper applications to control potato late blight in organic production systems.
The main objective of this project, VETAB project, is to determine alternatives to massive copper utilization to control potato late blight (Phytophtora infestans (Mont.) de Bary) in organic systems. To reach such a target, we first performed a screening of candidate products and additives based on their efficiency in the laboratory, under controlled conditions. We evaluated a wide range of pro...
متن کاملEffect 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 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...
متن کاملLate Blight Resistance of RB Transgenic Potato Lines
Late blight of potato (Solanum tuberosum L.), incited by Phytophthora infestans (Mont.) de Bary, is a devastating disease affecting tuber yield and storage. Recent work has isolated a resistance gene, RB, from the wild species Solanum bulbocastanum Dun. Earlier work in Toluca, Mexico, observed significant levels of field resistance under intense disease pressure in a somatic hybrid containing R...
