2. Live oak regrowth controlled with fenuron pellets. APPLICATION EQUIPMENT I Ihe major considerations when select- ing equipment are availability, efficiency, selectivity, and amount of spray drift. Mechanical agitation in the spray tank is essential when emulsions of 2,4-D, 2,4,5-T, and silvex are used. Back-pack knapsack and compressed air sprayers. Commonly used for treating in- dividual woody plants. Back-pack mist blowers. Useful when a small volume of spray mixture, or speedy application in a small area, is needed. Sprayers should be equipped with a quick shut-off valve near the opening where spray mixture enters the air-stream, and the orifice-opening should be adjustable at this same point. Allowance must be made for spray drift when using this equipment. Power sprayers. Used for spraying indi- vidual woody plants and for broadcast spraying. For hard-to-reach areas, side hoses may be attached to the main hose- line (pneumatic-type couplings facilitate operations). Spray booms or offset nozzles on mobile sprayers are sometimes used for spraying roadsides or fields of brush. Mounted mist blowers. Useful in areas where tractors can operate. Helicopters and airplanes. Helicopters have largely replaced the airplane for broadcast spraying, except on more easilv accessible areas. Difficult areas can be flown over successfully and relatively safely with a helicopter, and small clear- ings can serve as heliports. Spray drift is a problem in aircraft spray-application, but attempts are being made to minimize it through development of proper spraying devices. 9)
