A few soybean fields were planted early, and they are not only emerged, but well into the V-growth stages. Producers are just now finding that these “islands” of legumes have become a trap-crop for bean leaf beetle activity early this season; it certainly shows their flying, and locating, ability. From surprised producer’s descriptions of damage, the beetles have been feeding for some time. Though these overwintering adults will soon taper off in numbers, as they naturally die-off, some have chosen to protect the remainder of the crop to avoid replanting. With this crazy, delayed spring, replanting is not an option for many.
