The three growers have applied the 1/4 rates of Citrus Fix (2, 4-D), MaxCel (cytokinin) and now also ProGibb every 45 days on approximately 1 acre each of Hamlin and Valencia orange trees. Treated and Control trees are categorized by three levels of tree health and are being monitored for fruit drop, leaf drop, flushing, yield, etc. One other location is receiving similar treatments in a replicated trial. We are monitoring leaf drop to see if these frequent applications may affect leaf drop as well as fruit drop. If they do, it would more than compensate for keeping some additional fruit on the tree longer than normal for HLB affected trees.
