Lessons with plant growth regulators

November 2023 | Presented by Suzanne Bishop | Future Orchards®

This presentation reviews practical lessons from using plant growth regulators in orchard systems, with an emphasis on understanding why responses can vary between seasons, blocks and application timings.

Rather than treating a PGR response as automatic, the presentation encourages growers to connect product choice and timing with the physiological stage of the tree, cultivar sensitivity, environmental conditions and the outcome being targeted. That approach is especially important where the objective is to influence flowering, crop load, vegetative growth, maturity or fruit quality.

The resource complements earlier Future Orchards® PGR material by focusing on field experience and decision-making. It is particularly useful for growers comparing PGR programs and looking for a framework to interpret inconsistent results rather than simply repeating a spray program by calendar date.
