Precision Crop Load Management
Anna Wallis, Tree Fruit and Grape Specialist

Precision Crop Load Management (PCLM) is a 3-step process of managing apple crop loads more precisely:
1. Prune to a specific flower bud number
2. Chemically thin to a specific fruit number
3. Hand thin to a specific fruit number

Precision Chemical Thinning
Precision Chemical Thinning is the second leg of managing apple crop loads more precisely in the Precision Crop Load Management system. It utilizes sequential chemical thinning sprays guided by the use of the carbohydrate model and the fruit growth rate model to more consistently achieve a target crop load.
The presentation below on Precision Chemical Thinning was given by Terence Robinson on April 29, 2015. It explains the steps involved and outlines the protocol for the thinning trial being conducted in the 2015 season.
