Management of vegetative growth in apple trees with bioregulators

Summary: The objectives for this project were: 1. Explore possible methods for improving the efficacy of prohexadione-Ca (Apogee) for control of unwanted vegetative vigor, including application timing, concentration and combinations of Apogee with abscisic acid (ABA). 2. Examine whether ABA, the dormancy-inducing hormone, can be used either alone or in combination with other bioregulators to force terminal bud set or otherwise control extension growth in actively-growing apple shoots. 3. Determine if any successful growth-control treatments compromise fruit load, fruit growth or fruit quality in any way.
