Growers who target productivity, improved fruit sizing and finish, have found the combination of Screen Duo and Photon 500SG to be the ideal program over the summer months.
Two applications of Screen DUO early in the season gives leaves a reflective coating of kaolin to keep the tree cooler and reflect harmful UV rays.
A program application of Photon 500SG can then be implemented to allow ongoing heat stress mitigation without the issue of managing kaolin residue on the finished fruit.
Photon 500SG is a clear compound that leaves no residue. It triggers an enzymatic response within the plant to allow it to tolerate increased levels of abiotic stress. It is compatible with all other crop inputs so can be applied in conjunction with the normal spray program.
Unlike some kaolin products, Screen DUO is an easy-mix micro prill formulation. The micro prill is not a sharp structure and therefore will not deter predators.
