Abstract

The recent deluge of water has destroyed many corn fields and if the previously applied herbicide requires that corn be replanted, how do you kill the existing poor stand? If the corn hybrid was a known herbicide resistant cultivar, your options are somewhat limited. If the hybrid was Roundup Ready®, the use of Liberty® or paraquat are not likely to consistently control the emerged corn. If on the other hand, the cultivar was not Roundup Ready®, you have an excellent option with the use of glyphosate. Recognize that some corn hybrids are genetically engineered to be resistant to both glyphosate and Liberty®. It is suggested that you check with the seed company to make sure the hybrid you have is not resistant to multiple herbicides.
