Thermal inactivation of Phytophthora capsici oospores.
BACKGROUND Phytophthora capsici is a major fungal plant pathogen that causes root and crown rot of pepper crops and its oospores are the most resistant propagules. OBJECTIVES To evaluate the effect of different temperature regimes and exposure times on the survival of P. capsici oospores. METHODS Thermal inactivation treatments simulated field conditions, through the use of different consta...
متن کاملstudy the effects of low level laser diode on no production and healing of diabetic and cortisone acetate and normal wounded sd rats
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
15 صفحه اولFungicide Efficacy in Prevention of Root Rot Incited by Phytophthora cactorum and Phytophthora drechsleri in Fraser Fir Seedlings
The most serious disease problem in fraser fir (Abies fraseri) Christmas tree production is phytophthora root rot (PRR). The efficacies of six fungicide treatments in preventing PRR incited by Phytophthora cactorum and P. drechsleri in 2-year-old fraser fir seedlings were evaluated in 2010 and 2011 in central Pennsylvania. The study examined five fungicide drench treatments [dimethomorph, foset...
متن کاملEffect of Difenoconazole on the Formation of Oospores by Phytophthora Infestans (mont) De Bary
Fungicide difenoconazole is applied for field treatment to protect potato and tomato against early blight, caused by the Alternaria fungi. It is practically important to estimate the impact of difenoconazole application against late blight pathogen Phytophthora infestans (Mont.) de Bary because of early and late blight often come together on potato. Effect of fungicide difenoconazole on the rad...
متن کاملOccurrence of Oospores of Phytophthora Infestans in the Field and under Controlled Conditions
Both A1 and A2 mating types of Phytophthora infestans were detected in El-Behera governorate and the surrounding area where potato and tomato were intensively cultivated during the 2005-2006 growing season. The A2 mating type constituted 14.8% of the total isolates recovered (162) while A1 mating type constituted 83.9%. A 7.4% of the total potato and tomato fields (94) surveyed yielded A2 matin...
