Safening of Native Grass to Herbicides by Using Carbon Bands Academic Article uri icon

abstract

  • Greenhouse and field experiments were conducted to evaluate the use of a carbon band to provide a safe zone for seedling emergence and growth of three native grass species. KIKA677 streambed bristlegrass germplasm, Alamo switchgrass, and Waelder shortspike windmillgrass germplasm were used in combination with several PRE- and POST-applied herbicides including cloransulam, flumioxazin, imazapic, imazethapyr, and 2,4-D. In a greenhouse experiment, switchgrass emergence was improved when a carbon band was used with imazapic or imazethapyr at 0.04 and 0.07 kg ai ha1or 2,4-D at 2.12 kg ae ha1. Windmillgrass emergence was improved when carbon was used in combination with flumioxazin at 0.05 and 0.1 kg ai ha1, imazapic at 0.04 and 0.07 kg ha1, imazethapyr at 0.07 kg ha1, and 2,4-D at 1.06 kg ha1, whereas bristlegrass emergence was improved when carbon was used in combination with flumioxazin at 0.1 kg ai ha1, imazapic at both rates, and imazethapyr at 0.04 kg ha1. Field studies indicated that flumioxazin at 0.05 and 0.1 kg ha1, imazapic at 0.04 kg ha1, and imazethapyr at 0.04 and 0.07 kg ha1, were safened for bristlegrass and switchgrass emergence when used with carbon. Windmillgrass emergence and growth were improved when carbon was used in combination with flumioxazin at 0.1 kg ha1.
