I had the opportunity to participate in the Bayer Twin Link dual-Bt technology field tour near Blackville, SC, on August 23rd. Research on this technology was observed on the Clemson Edisto Research and Education Center and on the Carolina Ag Research farm (Dr. Mike McCarty). Both locations have had some of the highest bollworm pressure I have ever observed. Untreated conventional cotton had 100% boll damage and some foliage loss to bollworms. The Bayer Twin Link Bt technology did not give perfect control under this level of pressure but showed impressive results.
