1. Irrigation Effects, 1 st Trial Vs. Peachtree Borer Treatments: no irrigation, Irrigation (3X per wk over 2 wks), Barricade, chlorpyrifos (Lorsban) Figure 1 Lack of irrigation = fail With irrig – suppression Barricade trt = Lorsban

2. Effect of Application Method, 1 st Trial Vs. Peachtree borer Treatments: commercial nematodes with boom sprayer, handgun, trunk sprayer, non-treated control. In vivo nematodes with watering can, chlorpyrifos (pos control); E-nema with handgun Apply in fall, assess PTB infestation in spring Figure 2 7 trees per rep 3 reps per treatment High variation – no sig Treatment differences

3. Results of 1 st Trial After 1 h all treatments failed Barricade protected nematodes in single spray up to 30 min Figure 3

4. Field Trial Results vs. Lesser Peachtree borer : Nematodes + Barricade at full and 2% rates provided control equal to Nufos (Lorsban) Figure 4
