Other claims from this paper (19)
- Observation Early leaf spot appeared near the inoculation site 22 days after inoculation in 2000 and 23 days in 2001.
- Observation Intimate Intercrop reached approximately 41% mean disease incidence by day 63 in 2000.
- Observation Monocrop reached approximately 41% mean disease incidence by day 63 in 2000.
- Intervention effect In 2000 disease incidence AUDPC was greater for Intimate Intercrop than Strip Old.
- Intervention effect In 2000 disease incidence AUDPC was greater for Monocrop than Strip Old.
- Intervention effect In 2000 Strip Old disease AUDPC was greater than sprayed monocrop.
- Observation Natural Cercosporidium personatum populations caused a late leaf spot epidemic.
- Observation Monocrop reached 15% disease incidence at 62 days after inoculation in 2001.
- Intervention effect In 2001 Monocrop had significantly higher disease AUDPC than the other four treatments.
- Intervention effect In 2001 Intimate Intercrop disease AUDPC exceeded both Strip treatments and sprayed monocrop.
- Intervention effect Strip New had greater disease AUDPC than the spray treatment in 2001.
- Intervention effect Strip Old disease AUDPC was statistically similar to the sprayed treatment.
- Intervention effect Disease and intercropping did not significantly affect peanut yield in 2000.
- Intervention effect Intimate Intercrop significantly depressed peanut yield in 2001.
- Intervention effect Intercropping showed neither benefit nor reduction in corn yield.
- Association Treatment and distance interacted significantly during the last four sampling days of each early leaf spot epidemic.
- Method / resource Disease gradient models fit best when log distance was used in both years.
- Association Calculated velocity increased with increasing distance from the inoculum source.
- Observation Strip New had the highest calculated epidemic velocity at all distances in 2001.
