<b>Text Appearing After Image: </b><br><i>Light-weight portable spray rig that can be carried by two men to remote places. Water can be pumped from streams with the gasoline-driven pump. Hose of varying lengths can be extended from the tank. sible, agitation can be accomplished by a vigorous return flow of at least 10 per cent of the spray mixture from the pump. Small, light-weight power sprayers can be built, adaptable for use away from roads. The unit shown here can be easily carried by two men. Fill the fab- ric tank from a nearby stream, using the same pump that dispenses the spray solution. Use booms with power sprayers to spray areas uniformly. Equipment is still not available for spraying many types of brushy sites. Mist blowers These are used in orchards to apply insecticides to trees. The same type of blower has been used for roadside work and for control of big sagebrush. Al- though mist blowers have many limi- tations, they can be used for some brush spraying. Avoid drift onto sensitive crops. Aircraft Helicopters and airplanes are used to spray limited acreages of brush in Cali- fornia. Most spraying has been done using 10 gallons of total spray solution per acre. Wherever possible, flights should be flagged. Best results are ob- tained when the width of each flight path is not over 35 feet. Helicopters have been used mainly for spraying coastal brush, and airplanes for spray- ing big sagebrush. To insure better or more uniform coverage, areas are some- times flown twice. THE PHOTO ON PAGE 3 shows an operator using a knapsack sprayer with a double-action trombone pump.
