A low-volume herbicide applicator for tropical small-holder farms

, : A low-volume herbicide applicator for tropical small-holder farms. Proceedings 1980 British Crop Protection Conference Weeds: 629-636

A wheelbarrow sprayer suitable for use on small holdings in the tropics is described. Two peristaltic pumps, driven off the ground-wheel, deliver the spray liquid to a Micromax spinning cup, giving an application vol. of 20 litres/ha. The swath width is controlled by a shroud mounted around the cup with two variable shutters. Patternator tests show a variation across the swath of 10-25% over a range of walking speeds and flow rates for a swath up to 1.5 m.
