Abstract

Overall application of herbicides with hollow cone nozzles is common practice in second-crop maize in the Cukurova Region of Turkey. Effective integrated weed management tactics are needed for this region. Acetochlor and nicosulfuron, two commonly used herbicides in maize production, were applied pre-emergence and post-emergence, respectively. Spinning disc nozzles with a reduced spray volume did not improve weed control and with a reduced herbicide dose gave inadequate weed control. Banding was as effective as broadcast application. Different bandwidths with even flat fan nozzles, 15, 20, 25, 30, and 35 cm, gave similar weed control and maize yield. Banding decreased herbicide and water use by up to 78%.
