Abstract
The effect of postemergence applications of mefluidide at 0, 0.14, 0.28, and 0.56 kg/ha or MON 4621 at 0, 2.2, 3.3, and 4.4 kg/ha on growth and seedhead development of wild and cultivated proso millet (Panicum miliaceum L.) was determined. Application of mefluidide at 0.56 kg/ha 17 days after seeding reduced plant height and fresh shoot weight and inhibited panicle formation of both millets, whereas the 0.28 and 0.14 kg/ha rates had no effect on plant growth. When applied 23 days after seeding, mefluidide at 0.56 and 0.28 kg/ha reduced plant height of both millets and fresh shoot weight of wild proso millet. These rates also caused abnormal panicle formation. The 0.14 kg/ha rate had no effect on plant growth. All 3 rates of MON 4621, applied 16 days after seeding, reduced plant height and fresh shoot weight of both millets, and the 3.3 and 4.4 kg/ha rates were very effective in preventing panicle formation. Chemical names used: N-[2,4-dimethyl-5-[[(trifluoromethyl) sulfonyl]amino] phenyl]acetamide (mefluidide); (acetamide, N-[(acetylamino)methyl]-2-chloro-N-(2,6-diethylphenyl)(MON 4621).
