Two field experiments were conducted to compare the growth of sicklepod, Senna obtusifolia and the response of BXN 57 cotton to EPOST treatments of MSMA and Buctril, alone and in combination. The objective was to identify treatments which would suppress sicklepod and promote a height differential between the cotton and sicklepod. Height measurements of the cotton and sicklepod were taken over a four week period to record the length of time any differences were maintained as well as injury ratings and lint yields of the cotton.
