Other claims from this paper (11)
- Intervention effect The tested chemicals injured grape leaves and clusters.
- Association Leaf injury increased with Endothall concentration.
- Observation Vidal blanc was most sensitive to Endothall.
- Observation Chambourcin was most sensitive to ammonium thiosulfate.
- Intervention effect Hand thinning increased cluster weight, berries per cluster and juice soluble solids.
- Intervention effect Hand thinning increased juice pH.
- Intervention effect Hand thinning decreased yield, with Seyval blanc affected in only one year.
- Association Thinning increased with Endothall concentration.
- Intervention effect Endothall at 1.92 ml-L-1 reduced yield and increased soluble solids and pH similarly to hand thinning.
- Intervention effect Wilthin at 1.92 ml-L-1 generally resembled hand thinning, though juice quality gains were less consistent.
- Intervention effect Ammonium thiosulfate caused excessive leaf injury and crop reduction in warm, humid conditions.
