Abstract (AB)	In Mauritius, flood jet and double hollow cone nozzles are used on knapsack sprayers for applying herbicides in sugar cane whereas standard flat fan nozzles are most common on boom sprayers. The spray distribution from all these nozzles include fine droplets that may be easily carried by wind and cause damage to susceptible crops grown in the neighbourhood. Air-inclusion nozzles (flat fan type), designed to produce coarser droplets and reduce spray drifts, have been evaluated for herbicide application in sugar cane; the new nozzles were tested more particularly for their herbicidal efficacy in post-emergence of weeds and sugar cane. Results show that post-emergence weed control obtained by the Air-Bubble Jet nozzles is comparable to the hollow cone nozzles (on knapsack sprayers) and flat fan nozzles (boom sprayers. Air Inclusion (wide angle) nozzles tested on knapsack sprayers were found to be superior to the flood jet nozzles and comparable to double cone jet nozzles. With two passes per cane interrow, an Air Inclusion (wide angle) nozzle mounted on a knapsack sprayer enables significant reduction of spray volume usually required with the double cone jet nozzles.
