With this type, a hose may be used to connect boom across Hand Booms,.. For fence rows, scattered weed patches, areas around buildings, and in the gar- den, a hand boom with a knapsack or small power sprayer is very useful. Hand booms are also used with the large sprayer to cover small areas inaccessible to the fixed boom. The commercially made, lightweight boom with 1 to 3 noz- zles, quick shut-oif valve, and 25 feet of oil-resistant hose is the most satisfactory. Homemade booms can be built from pipe fittings, but are rather heavy and clumsy if made from iron pipe. Commercial booms are made of aluminum or similar lightweight metals. It is best to buy the light metal hand booms already formed and threaded for nozzle and hose con- nection because it is difficult to weld these metals in the farm shop. A control valve should be placed be- tween the hose and the boom. The most convenient type valves are spring-loaded, lever-operated. Squeezing the valve lever against the boom with one hand opens the valve; releasing the lever closes it. The two booms at top are of %-inch iron pipe; the two at the bottom are of lightweight aluminum alloy. [23.
