1. To determine the optimum method of applying entomopathogenic nematodes for control of peachtree borer. 2. To determine the optimum formulation of applying entomopathogenic nematodes for control of lesser peachtree borer. 3. To assess the impact of entomopathogenic nematodes application on the indigenous natural enemy complex.
Three methods of entomopathogenic nematode application (trunk sprayer, microjet irrigation, and herbicide boom) will be compared under field conditions for efficacy in suppression of peachtree borer. A variety (ca. 12) of formulations will be field-tested for their ability to protect nematodes from UV radiation and desiccation, and efficacy in suppressing lesser peachtree borer. Laboratory tests on nematode viability in the various formulations will support field data. Field surveys of indigenous natural enemies will be implemented.
