When traditional approaches, hand thinning and highly weather-dependent plant hormone-based thinners weren't working, ADAMA New Zealand took a different tack, an innovative approach backed by data, science and collaboration.It began with photosynthesis-inhibiting fruitlet thinner Brevis, now used in 30 countries worldwide.Applied when fruitlets are about 8-14 mm in size and mimicking the effect of shade, Brevis reduces the production of carbohydrates by the tree. Remaining carbohydrates are sent to shoots and to the largest, dominant 'king' fruitlets at the expense of smaller fruitlets, which start to drop in seven to 10 days after treatment.
