Meristem culture for the elimination of the strawberry crown rot pathogen Phytophthora cactorum
Two methods to induce a symptomless infection of crown rot (Phytophthora cactorum) in stolons of three strawberry (Fragaria×ananassa) cultivars were evaluated. Spraying a 10−4 ml zoospore suspension was the most effective method, producing a mean infection rate of 12%. Meristem cultures were subsequently established from all of the inoculated stolons and tested eight weeks later for the presenc...
متن کاملFungicide 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 کاملThe Effects of Heavy Metals and Root Immersion on Isoflavonoid Metabolism in Alfalfa (Medicago sativa L.).
Modest increases in the concentration of medicarpin, 6-fold in leaves and 4-fold in roots, were observed in alfalfa (Medicago sativa L.) seedlings treated with 1 mM metal salts for 72 h. However, medicarpin-3-O-glucoside-6"-O-malonate (MGM) and formononetin-7-O-glucoside-6"-O-malonate (FGM) levels were up to 50-fold lower in metal-treated compared to control roots. Approximately 10% of the "mis...

متن کاملAbstract Withholding alfalfa (Medicago sativa L.) irri-
Withholding alfalfa (Medicago sativa L.) irrigations during the summer, a practice referred to as summer irrigation termination (SIT), can conserve substantial amounts of water in long-season desert environments; however, plant mortality associated with SIT may be substantial. Proper timing of re-irrigation is critical for minimizing mortality and yield reductions following SIT. Procedures that...
