Technical Abstract: Field studies were conducted to evaluate hooded sprayer-applications of glyphosate at 3.4 and 4.5 kg ai/ha in the spring or fall on bermudagrass growing between and within the sugarcane drill. Good to excellent control was observed in a ratoon field where bermudagrass was contacted by the spray droplets following spring applications of glyphosate. However, there ewas little evidence of its translocation out of the 1.2 m treated area to bermudagrass growing in the 60 cm wide sugarcane drill. Fall applications of glyphosate were made in a newly planted field where bermudagrass development was limited to the wheel furrows and row sides and in a field of sugarcane harvested 4 wk earlier to propagate adjacent fallow fields. Glyphosate provided excellent control of bermudagrass in the inter-row spacing 4 WAT in both studies, and there was some evidence of translocation away from the treated area to bermudagrass growing in the sugarcane drill in the seedcane field. In both the newly planted and seedcane fields, fal applications of glyphosate resulted in lower bermudagrass infestation levels in the spring. However, in neither study, was bermudagrass eliminated or sugar yields increased.
