Other claims from this paper (19)
- Observation Coccinia grandis was highly resistant to gummy stem blight.
- Observation The first susceptibility report for 14 species expanded the S. citrulli host range to 37 species in 21 genera.
- Observation Crown cankers were important reproductive sites for S. citrulli.
- Observation Six fungal pathogens, one oomycete and three viral pathogens were identified on watermelon.
- Observation Myrothecium s.l. was the most common pathogen in fall 2017.
- Observation Corynespora cassiicola was the third most common pathogen in fall 2017.
- Observation Eight of 80 Stagonosporopsis isolates were S. caricae.
- Observation The remaining Stagonosporopsis isolates were S. citrulli.
- Observation C. cassiicola, S. caricae and Myrothecium s.l. were first reported on watermelon in South Carolina.
- Association Stagonosporopsis occurrence probability increased in fields with a previous cucurbit crop.
- Association Pathogen occurrence probabilities increased with plant age.
- Association Some pathogen occurrence probabilities were lower on triploid than diploid cultivars.
- Association Pathogen occurrence probability decreased in fields aligned southwest or west.
- Observation Six Stachybotriaceae species were identified among 95 isolates from 11 South Carolina fields.
- Observation Gregatothecium humicola and Paramyrothecium foliicola predominated in the collection.
- Observation Genetic differences at small spatial scales occurred within both predominant species.
- Observation The two predominant species were the most virulent on watermelon.
- Observation Cowpea was less susceptible than watermelon and tomato, which were equally susceptible.
- Observation The study first reported pathogenicity of five Stachybotriaceae species on the three crops and X. tongaense on watermelon.
