Insecticides were applied to mature peach trees on the Trevor Nichols Res. Complex (Peach 2) at a rate of 100 gpa with an FMC 1029 airblast sprayer. Treatments were arranged as completely randomized units consisting of single trees, each replicated 4 times. Applications were made on 17 May (PF), 26 May (SS), 7 Jun (1C), 21 Jun (2C), 1 Jul (3C), 12 Jul (4C), 28 Jul (5C) and 9 Aug (6C). Rovral, Ziram and Wettable Sulfur were applied separately to all treatments. An OFM flagging evaluation was done on 28 Jun by inspecting 50 terminals randomly from each tree for a total of 200 terminals per treatment. A mid-season fruit evaluation was done on 6 Jul, by picking 50 fruit per replicate for a total of 200 apples per treatment. A harvest fruit evaluation was done on 11 Aug by picking 50 fruit randomly from the periphery of the tree from each replicate, for a total of 200 fruit per treatment.
