"It has a fast knockdown from the bifenthrin while the Rynaxypyr active will give you the longer residual activity," Johnson said. Examining soybean looper trials across eight states, Vantacor, Elevest, and Besiege had similar control while Intrepid Edge had less control. "All products performed better than the untreated check, which was the number of larvae per 25 sweeps," he said. Looking at green cloverworm in another data trial, Elevest performed well and had more control than Besiege. Vantacor, Elevest, and Besiege all provided good control from the research data out of Virginia Tech, North Carolina State University, University of Georgia, and Clemson University.
