Podosphaera xanthii but not Golovinomyces cichoracearum infects Cucurbits in a Greenhouse at Salinas, California
Cosme Bojorques Ramos Karunakaran Maruthachalam, James D. McCreight Raymundo S. Garcia Estrada Traditionally, Erysiphe cichoracearum (now Golovinomyces cichoracearum) and Podosphaera xanthii, formerly Sphaerotheca fuliginea, have been reported as the causal agents of cucurbit powdery mildew (CPM) (2, 10). These two fungal species have often been misidentified (12), due to similarities in their anamorphic characteristics and […]
Powdery Mildew Resistance of Cucurbits at Different Locations
R. W. Robinson Horticulture Dept., Cornell University, Geneva, NY 14456 A sabbatical leave in 1968/69 provided an opportunity for me to visit research institutes in five different countries and test cucurbits for powdery mildew resistance at each location. Sixteen accessions of six cucurbit species were inoculated with powdery mildew spores in greenhouses at Geneva, NY; […]
Antagonistic Actinomycete XN-1 from Phyllosphere Microorganisms of Cucumber to Control Corynespora cassiicola
Strain XN-1 isolated from the cucumber phyllosphere was tested for potential application as an antagonistic actinomycete against Corynespora cassiicola (Berk.& Curt.)Wei. The fungistatic activity of this strain was determined by inoculation of C. cassiicola on PDA plates, spore germination inhibition in culture filtrate and control tests on cucumber leaves. The spore germination and hyphal growth […]
Genetic Control of Downy Mildew Resistance in Cucumber – A Review
The oomycete pathogen Pseudoperonospora cubensis (Berk. and Curt.) Rostow. is a major foliar disease of cucumber (Cucumis sativus L.), especially in humid regions of the world (Palti and Cohen, 1980). Downy mildew was first described on cucumber by Berkeley and Curtis in 1868 and investigation into the genetic basis of resistance began in the early […]
Yield of Spring-Planted Cucumber Using Row Covers, Polyethylene Mulch, and Chilling Resistant Cultivars
North Carolina is a leading producer of field-grown cucumbers (Cucumis sativus L.) in the United States. In the 2001 to 2003, North Carolina ranked second in the production of processing (pickling) cucumbers, after Michigan, with approximately 74,700 Mg harvested per year. In the same period, North Carolina ranked fifth in the production of fresh-market (slicing) […]
