AVG could be a valuable new tool, along with NAA, for preventing premature fruit drop in pears. Some questions for future research are: Can the initiation of internal ethylene development in pear be predicted to better time applications? Ethylene curves have been developed for pear once harvested, but not for fruit on the tree. What active ingredient concentration is needed for different cultivars, tree size, and crop loads? Large trees may require more material per tree to achieve desired results. How do growing season and weather affect maturity and enhance or impede results?  Drop control in apples is better during […]
