Fungicide 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 کاملManagement of Phytophthora Root and Runner Rot in Cranberry
Phytophthora is a genus of plant pathogens, many species of which live in water or soil. The name means “plant destroyer” in Greek. Phytophthora species are common pathogens in agricultural systems, especially in those where the crop is irrigated with surface or recycled water. In cranberry culture, the most troublesome species is P. cinnamomi, the cinnamon fungus. This pathogen causes a very c...
متن کاملMeristem 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 کاملImproving field establishment of safflower in soils infected by Phytophthora drechsleri and Pythium ultimum
One of the major field constraints to seed production in safflower has proven tobe soil born pathogens, Phytophthora drechsleri and Pythium ultimum. In order toevaluate the efficiency of a field-laboratory selection method to improve resistanceof safflower against soil born pathogens, Ph. drechsleri and P. ultimum, a two-yearinvestigation was conducted. The results showed that selection is an e...
