abstract   bibtex   
An experiment was conducted at two locations in Georgia and two locations in North Carolina during 1994 and 1995 to evaluate weed management in conven- tional-tillage bromoxynil-resistant Gossypium hirsutum L. (cotton). The weed man- agement systems evaluated included different combinations of fluometuron pre- emergence (PRE), bromoxynil or bromoxynil plus MSMA early postemergence (EPOST), bromoxynil postemergence (POST), and cyanazine plus MSMA late post- directed (LAYBY). Fluometuron PRE improved control of Acanthospermum hispi- dium DC. (bristly starbur), Cassia occidentalis L. (coffee senna), Chenopodium album L. (common lambsquarters), Desmodium tortuosum (Sw.) DC. (Florida beggarweed), Sida spinosa L. (prickly sida), Jacquemontia tamnifolia (L.) Griseb. (smallflower morn- ingglory), and Anoda cristata (L.) Schlecht. (spurred anoda), compared to systems that did not use fluometuron PRE. It also improved G. hirsutum yields at three of four locations. Bromoxynil-containing systems provided better weed control and higher G. hirsutum yields than systems without bromoxynil. Bromoxynil EPOST controlled A. hispidium, C. occidentalis, C. album, D. tortuosum, S. spinosa, J tam- nifolia, and A. cristata. Control of these species was frequently improved by a second application of bromoxynil POST. Bromoxynil EPOST, POST, or EPOST plus POST did not control Senna obtusifolia (L.) Irwin and Barneby (sicklepod), but the addition of MSMA to bromoxynil EPOST improved S. obtusifolia control. Control of all dicotyledonous weeds was improved by a LAYBY treatment of cyanazine plus MSMA, and yields were improved at three of four locations with this treatment. Gossypium hirsutum was not injured by POST treatments of bromoxynil, and only temporary injury resulted from POST treatments of MSMA.
