How biological controls are applied can affect their success as part of a pest control program—and proper handling of nematodes is no exception. Chart 1 Comparison of circulation method on nematode solution temperatures over eight hours. Temperaturesof stock solutions mixed by using air circulation remained relatively constant over eight hours. Temperatures of stock solutions mixed by using mechanical circulation caused temperatures to rise above 95 deg F (35deg C) over eight hours. Temperature increase in stock solutions can be mitigated by the addition of cold packs.
