These are three year old bark grafts on some of our trees. At this stage special care still has to be taken to brace the graft so it doesn’t break off during strong winds. Use wood and ties that don’t cut into the wood to brace it properly. The last thing you want is for a graft to break off the tree once it gets some size on it!
Dr. Tim Brenneman’s early results of his fungicide trials for the year have revealed a significant finding that could be of value to your scab management program. Dr. Brenneman’s results showed that adding a surfactant to the DMI/Strobilurin mix fungicide products like Absolute significantly reduces the incidence and severity of leaf scab over the fungicide alone. Similar results are expected with the effect on nut scab. Dr. Brenneman used a 90/10 surfactant but expects the same results could be obtained with an 80/20 surfactant. Also, similar results would be expected with the other DMI/Strobi mix fungicides like Quadris Top and Quilt. DO NOT ADD A SURFACTANT WHEN USING ELAST due to the increased risk for burn.
