Herbicide-Resistant Kochia, Palmer, and Waterhemp in the Panhandle: Distribution and Management
January 8, 2018
Several field trials were undertaken in 2017 to look at options for controlling herbicide-resistant kochia, Palmer amaranth, and waterhemp in dry bean, corn, and sugarbeet. In addition over 80 kochia, Palmer amaranth, and waterhemp plants were collected for testing of herbicide resistance. Of these 50% of kochia and 13% of Palmer amaranth plants tested were resistant to field rates of glyphosate. While options are limited in the Panhandle, pairing crop rotations with herbicide programs using PRE and layby treatments provided effective control of key weed species.
