Novaluron is a new generation benzoylphenyl urea active against insects of the orders Lepidoptera, Coleoptera, Hemiptera and Diptera through both larval ingestion and contact. This insect growth regulator has been field tested in cotton across the U.S.A. since 1998. Rates as low as 0.011 to 0.022 lbs. ai per acre are shown to control Bemesia argentifolii immatures, equivalent to current standard products. The heliothines, Heliocoverpa virescens and H. zea, exhibited a rate response to novaluron and appear to require at least 0.04 lbs. ai per acre to achieve acceptable control. Activity on foliar feeding Lepidoptera is expected. A rate response on Lygus (spp.) was also seen in field trials with 0.04 lbs. ai novaluron per acre giving similar nymph control to current standards. Research continues across the cottonbelt to further define rates and insect spectrum.
