Irrigation Effects, 1stTrialVs. 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
Effect of Application Method, 1stTrialVs. 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
Results of 1st Trial • After 1 h all treatments failed • Barricade protected nematodes in single spray up to 30 min Figure 3
Field Trial Results vs. Lesser Peachtree borer: • Nematodes + Barricade at full and 2% rates provided control equal to Nufos (Lorsban) Figure 4
