In 2006, Belt
TM (flubendiamide) was evaluated in studies in
Arkansas and
Louisiana. Field experiments were conducted in
Jefferson County,
Arkansas and at
Winnsboro, Louisiana at the Macon Ridge Research Station to evaluate the efficacy of Belt insecticide compared to existing and experimental insecticides to control the heliothine complex. The treatments selected for the Arkansas study were Belt at multiple rates, Belt and Larvin (thiodicarb) tank mixed, Larvin alone, Tracer (spinosad), Tracer and Capture (bifenthrin) tank mixed, Experimental I, Denim (emamectin benzoate), and Steward (indoxacarb). Significant differences were observed among treatments for seasonal total damage and seasonal total larvae. The treatments selected for the
Louisiana study were Belt at multiple rates, Belt and Larvin tank mixed, Larvin, Tracer, and a Bollgard II variety. Significant differences were observed among treatments for seasonal total damage and yield.
