Other claims from this paper (9)
- Intervention effect GA3 treatment of individual clusters tended to increase cluster weight and length, with differences not always significant.
- Intervention effect Iprodione fungicide provided good control of Botrytis bunch rot.
- Intervention effect Leaf removal reduced incidence to approximately 50% of that achieved by the fungicide.
- Intervention effect GA3 application at bloom did not affect yield in most years.
- Intervention effect In 1999 GA3 reduced the yield of Vignoles by 37%.
- Intervention effect In 1999 GA3 reduced the yield of Pinot Gris by 40%.
- Intervention effect None of the treatments affected juice quality.
- Intervention effect Exposing clusters by leaf removal alone was sufficient to control bunch rot on susceptible cultivars under humid Midwest conditions.
- Recommendation Leaf removal or GA3 cluster treatment should be integrated with a fungicide program.
