John Evans considered the pests and diseases in his Tasmanian orchard were under control, despite some edge issues with codling moth, and he used a minimal spray program.
Earwigs and A. mali were present and controlling WAA despite a spring application of chlorpyrifos against the Tasmanian dimple bug. He experimented with the codling moth line trapping concept, introduced by visiting scientist Chris Adams from Michigan State University in the 2018-19 training workshops, to identify appropriate timing of codling moth sprays and avoided the edge effects experienced in the previous season.
Damage recorded at harvest in the case study Fuji block was below economic thresholds with 0.2% codling moth, 0.2% apple scab, 2% of leaves with mites, and 14% of leaves showing signs of canary fly.
