Chris DiFonzo, a Michigan State entomologist, has compiled with colleagues a farmer-friendly table of allcorn and trade names. A special feature of the 2017 version of the table is getting a lot of attention – a column designating which insects, including the Southwestern corn borer larvae shown here, may be resistant to a give in a specific area.
A total of 29 corn varieties are listed in the table. All but three are listed as possibly -ineffective against one or more insects the initially controlled. All three of these varieties contain Syngenta’s Vip3A , combined with Cry1Ab or Cry1Ab+Cry1F.
Each of Dow AgroSciences’scorn varieties, and the six marketed by Monsanto are now compromised for one or more target insects.
