Annual Plum Reports Control of Shoot Growth in 'French' Prune by Apogee
Applications of this shoot growth inhibitor did reduce shoot grown, however the product will likely not be labelled for this crop in California. Submitted to the Dried Plum Advisory Board of California for 2003.
Annual Plum Reports CPPU for Harvest Delay, Improved Fruit Firmness and Reduction of Preharvest Drop in Prunus domestica L. ('French' prune), 2007
Trials to verify previous findings: treatments of growth regulator CPPU resulted in improved fruit quality and decreased fruit drop. Submitted to the Dried Plum Advisory Board of California for 2007.
Annual Plum Reports CPPU for Harvest Delay, Improved Fruit Firmness and Size and Reduction of Preharvest Drop in Prunus domestica L. ('French' prune), 2006
Evaluation of effect of CPPU treatments at four times during growing season on fruit quality, fruit drop and yield. Submitted to the Dried Plum Advisory Board of California for 2006.
Annual Plum Reports Effects of CPPU on Maturity Delay, Fruit Firmness and Fruit Drop in 'French' Prune, 2006
Evaluation of effect of CPPU treatments at four times during growing season on fruit quality, fruit drop and yield. Submitted to the Dried Plum Advisory Board of California for 2006.
Annual Plum Reports Use of Gibberellin for Timing of Fruit Maturity and Improved Firmness in 'French' Prune
Results suggest that fruit treated with ProGibb could be harvested later than untreated fruit, allowing a delayed harvest. Submitted to the Dried Plum Advisory Board of California for 2004.
Annual Plum Reports Use of the Dynamic Model and Application of Rest Breaking Agents in California Prune Production, 2005
Evaluation of dormant oil and CAN17 treatments on bud break and bloom progression in a commercial orchard, and use of the Dynamic Model to time the chill accumulation onset. Submitted to the Dried Plum Advisory Board of California for 2005.
Annual Plum Reports Using the Dynamic Model to Time Sprays of Rest Breaking Agents In California Prune Production, 2005-2007
Evaluation of timed treatments of CAN17 + N-Ter (RBAs) to advance bloom, and testing of the Dynamic Model (Fishman,1987) for timing applications of defoliants, dormant oil and RBAs for bloom and harvest advance. Submitted to the Dried Plum Advisory Board of California for 2007.
