Glucanolytic Actinomycetes Antagonistic to Phytophthora fragariae var. rubi, the Causal Agent of Raspberry Root Rot.
A collection of about 200 actinomycete strains was screened for the ability to grow on fragmented Phytophthora mycelium and to produce metabolites that inhibit Phytophthora growth. Thirteen strains were selected, and all produced (beta)-1,3-, (beta)-1,4-, and (beta)-1,6-glucanases. These enzymes could hydrolyze glucans from Phytophthora cell walls and cause lysis of Phytophthora cells. These en...
متن کاملOrganic Management of Raspberry Root Rot
PROCEDURES: We conducted two studies to investigate an integrated program for root rot (Phytopthora fragriae var. rubi) control in raspberries that would be useful to organic and conventional growers. These two studies have been carried out on our commercial field of ‘Meeker’ that was established in 1997 on raised beds with drip irrigation. Soil at this site is naturally infested with the root ...
متن کاملSuppression of Phytophthora Root Rot in Red Raspberries with Cultural Practices and Soil Amendments
Various soil amendments and cultural practices were examined in both a phytophthora-infested (Phytophthora fragariae var. rubi) (+PFR) and uninfested fi eld (–PFR) planted to ‘Heritage’ red raspberries. Although plants in the +PFR fi eld did not exhibit typical disease symptoms due to unseasonably dry weather, their growth was less than those in the –PFR fi eld. After 2 years, plants in the +PF...
متن کاملFine Mapping and Identification of a Novel Phytophthora Root Rot Resistance Locus RpsZS18 on Chromosome 2 in Soybean
Phytophthora root rot (PRR) caused by Phytophthora sojae is a major soybean disease that causes severe economic losses worldwide. Using soybean cultivars carrying a Rps resistance gene is the most effective strategy for controlling this disease. We previously detected a novel Phytophthora resistance gene, RpsZS18, on chromosome 2 of the soybean cultivar Zaoshu18. The aim of the present study wa...
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...
