- Intervention effect Witchweed reduced sorghum host-shoot yield by about 45% at the highest nutrient level.
- Observation Witchweed produced seed at all nutrient levels on sorghum.
- Observation Sorghum host produced seed only at the highest nutrient level.
- Association Increased nutrition also increased witchweed yields on sorghum.
- Intervention effect Early witchweed attack was more destructive to the sorghum host than a late attack, regardless of nutrient level.
- Intervention effect Removing the host shoot inhibited witchweed growth.
- Intervention effect Feeding sucrose to witchweed did not restore parasite growth after host shoot removal.
- Intervention effect Mineral nutrients were toxic to the detached witchweed parasite.
- Intervention effect High relative humidity around witchweed protected it from nutrient toxicity.
- Intervention effect High relative humidity enhanced survival of the detached witchweed parasite.
- Intervention effect High relative humidity markedly inhibited witchweed growth in the intact sorghum parasite-host relationship.
