Other claims from this paper (14)
- Association Disease incidence and severity were higher in 2003 than in 2004 at similar levels of added inoculum
- Association Disease incidence and severity correlated with the amount of added infested straw inoculum
- Observation Maximum disease incidence under artificial soil infestation was 54.3%
- Observation Maximum disease severity under artificial soil infestation was 0.57 on a 0-2 scale
- Intervention effect Artificial soil infestation at these maximum DI and DS levels did not induce significant yield reduction in whole plots
- Intervention effect Yield decreased significantly on single naturally infected plants removed from the field at growth stage 83 to 85
- Association Systemic spread of V. longisporum was significantly delayed in field plants, with shoot colonization not before maturity
- Association Fungal systemic spread into the shoots was faster in 2003
- Observation The pathogen systemically spread after 28 days in the greenhouse in susceptible cultivar Falcon
- Intervention effect Root dip inoculation with conidia suspension induced earlier and more severe disease symptoms than microsclerotia added to the soil
- Observation Intense stunting was recorded on inoculated plants in the greenhouse, in contrast to the field
- Association Susceptible cultivar Falcon showed higher disease severity than moderately susceptible Talent
- Association Falcon showed stronger reduction in root and shoot lengths than Talent
- Association Falcon showed a faster fungal spread in plant tissue than Talent
