For pecan spraying, a tank having a minimum capacity of 300 gallons is desirable. The pump should deliver 20 to 30 gallons per minute and maintain a pressure of 400 to 600 pounds per square inch while operating. A spray gun which is adjustable to produce a mist spray for spraying small trees or the lower canopy of large trees and a narrow stream that will reach the tops of tall trees is essential. For safety and durability high pressure rubber hose having an inside diameter of three-fourths inch should be used with all high pressure spray machines. _Literature Cited_ [1]Bilsing, S.
