Upland and Pima Cotton Demonstration Using IGR's Knack and Applaud to Control Silverleaf Whitefly at the Yuma Valley Ag Center in 1996
The section 18 granted for the use of insect growth regulators in 1996 in Arizona provided an excellent opportunity to demonstrate the efficacy of the materials. Knack® (Pyriproxyfen) and Applaud® (Buprofezin) both demonstrated excellent control of whitefly in this demonstration. Efficacy of the ins...
