PHYTOTOXICITY AND EFFICACY OF BALANCE FOR
WEED CONTROL IN FIELD CORN
Bradley A. Majek'
ABSTRACT
ance was evaluated in no-till and conventionally planted field com at Rutgers
Agricultu Research and Extension Center in 1996. The Balance rate considered as the use
rate in th no-till com was 0.094Ib aila, while the rate used in the conventionally planted com
was 0.07 lb ai/a. Large crabgrass Dil:itaria sanl:uinalis (L.) Scop., common lambsquarter
h . m L., and smooth pigweed Amaranthus hybridus L. were present in the no-till
study. e weeds in the conventionally planted study were giant foxtail Setaria~ Herrm.,
common bsquarter, smooth pigweed, and wild buckwheat PoIYl:0numconvolvulus L. Weed
control' the No-till com was marginally unacceptable, where large crabgrass and smooth
pigweed ntrol dropped below eighty percent. Control of weeds in the conventionally planted
com was ood with the exception of wild buckwheat which was not controlled by Balance. No
com inj was observed in the no-till study due to Balance applications, but slight,
nonsigni cant injury was observed in the conventionally planted study. Tank-mixing Balance
with a .ne improved weed control, including wild buckwheat, without increasing crop injury.
Tank-mi with Dual or Topnotch increased crop injury and did not control wild buckwheat.
