Effect of imazapic application timing on texas peanut(arachis hypogaea)

摘要

Field experiments conducted in Texas at six locations from 1996 to 1998 evaluated peanut tolerance to imazapic applied postemergence. Imazapic at 71 g ai/ha was applied weekly from ground cracking to 56 d after ground cracking(DAGC). Visible injury 70 DAGC ranged from 0 to 40/100. No reduction in canopy height, canopy width, yield, or grade was observed at harvest following any Imazapic treatment.
