Other claims from this paper (6)
- Intervention effect Rumex obtusifolium root extracts significantly reduced powdery mildew infection on apple seedlings in greenhouse screening.
- Intervention effect Rumex obtusifolium extract treatments every 7–10 days were less effective in field apple trials.
- Intervention effect Saponin-containing plant extracts gave satisfactory scab control on apple seedlings in a growth chamber.
- Intervention effect Saponin-containing plant extracts were not very effective against apple scab in the field.
- Intervention effect Chaetomium spore suspensions and culture filtrates reduced scab infection on apple seedlings to some extent.
- Mechanism The authors attribute poor efficacy of the hyperparasite control system to its delayed spread.
