Other claims from this paper (9)
- Observation Affected plants showed interveinal chlorosis, necrosis and vascular discoloration.
- Observation F. solani f. sp. glycines was isolated from symptomatic soybean plants.
- Intervention effect Root inoculation with each of five isolates caused typical SDS symptoms in four soybean cultivars relative to uninoculated plants.
- Observation Foliar symptom incidence differed among the four soybean cultivars: Conrad 6%, A2540 10%, S19-90 14% and Ripley 17%.
- Observation F. solani f. sp. glycines was reisolated from symptomatic roots.
- Intervention effect Ripley developed foliar and root symptoms after inoculation with each Ontario isolate.
- Observation Diseased soybean plants had few, poorly filled pods.
- Observation Soybean growth was severely restricted over two hectares in each of two fields where soybean cyst nematode was present.
- Observation The authors concluded that the SDS pathogen was widely distributed in southwest Ontario and disease severity was increasing.
