Description of a modified hand‐held ultra‐low‐volume sprayer for millet crop protection by Sahelian farmers

Abstract

The evolution and design of two versions of a modified Micro‐Ulva hand‐held u.l.v. sprayer are described. These sprayers have resulted from the need by the Mali Millet Pest Control Project, under the auspices of the Overseas Development and Natural Resources Institute of the Overseas Development Administration, to develop equipment suitable for use by subsistence farmers in the control of grasshoppers and millet head miner or millet spike worm. The Mali‐1 sprayer has been used in 1987 and 1988. The Mali‐2 has been used in 1989.
