Abstract
Command 3ME provides better and more consistent control of common lambsquarters (Chenopodium album), velvetleaf (Abutilon theophrasti), and prickly sida (Sida spinosa) than Roundup Ultra. However, Roundup Ultra provides better control of pigweed species (Amaranthus sp.) than Command 3ME, which does not control pigweed species. The PPI herbicide, Treflan, is commonly used for grass and small-seeded broadleaf weed control in cotton (Gossypium hirsutum). Treflan must be incorporated, which is costly to growers, and may potentially delay planting during wet years. Thus Command 3ME PRE seems to fit well into the Roundup Ultra systems. The objective was to evaluate Command 3ME PRE versus Treflan 4EC PPI in systems for weed control in Roundup Ready cotton. The study was conducted in Rocky Mount, NC in 1997 and 1998, and in Clayton, NC in 1998. Treatments included: Command 3ME PRE at 1.3 pints/A, Treflan 4EC PPI at 1 pint/A, Command PRE or Treflan PPI followed (fb) by Roundup Ultra AS NEEDED at 1.5 pints/A, Command PRE or Treflan PPI fb Cotoran 4L PRE at 2 pints/A, Command PRE or Treflan PPI fb Cotoran PRE fb Roundup Ultra AS NEEDED, Command PRE or Treflan PPI fb Roundup EPOST fb Bueno 6 at 2.7 pints/A + Bladex at 1.6 pints/A LAYBY, and Command PRE or Treflan PRE fb Cotoran fb Roundup Ultra EPOST fb Bueno 6 + Bladex LAYBY.
