Abstract: Previous small plot studies with commercially produced Steinernema carpocapsae demonstrated that this species could infect overwintering larvae of the Navel Orangeworm (Amyelois transitella) infesting pistachios on the ground. Applications were made from October through April and the nematodes were effective when soil temperatures did not exceed 32°C during the day or fall below 5°C at night. Although these small-scale applications were successful this nematode needed to be evaluated in large scale trials. Applications were made to the berm as well as the entire orchard floor in some trials as well as by herbicide applicator and chemigation. Nematodes were applied at a concentration of 1.24 billion per ha in a volume of 1,869 1 per ha by herbicide applicator and through microsprinklers and double drip irrigation. Applications failed when the nematodes were applied using double drip irrigation but succeeded when microsprinklers were used (output of 22 liters per hour, run for 6 hours). Applications made by herbicide applicator were successful when post application irrigation was supplied by microsprinklers.
