These sprayers are for use on a comparatively small area, but one which is too big for coverage by a hand sprayer. Any small pump and engine unit which will discharge 2 to 4 gpm (gallons per minute) at 50 to 75 psi will be satis- [ factory for general weed spraying. It will carry a hand boom or gun of 2 or 3 noz- zles. NOTE: Units which combine low volume (2 to 4 gpm) and low pressure (20 to 50 psi) may be used
