North Central Iowa | must be the differences in the country. In north iowa we are growing lots of corn and between diapause rootworm ( northerns) and the buildup of westerns in the continuios corn. You are foolish to plant non traited corn without full load of insecticide, VT3 will not hold in multi year coc. we have had diapause Rootworm problems since the mid 80's here, long before traited corn. Smartstak corn does seem to hold up to the pressure for now. and yes there is almost always a slight change in the hybrid when a trait is inserted but I have seen it work both ways in the past where the traited was hands down a better hybrid too. | |
