SPRAYING FOR CITRUS INSECTS AND MITES IN FLORIDA. 25 



so that it can be very easily removed or ''jumped" out. After this 

 is done a paddle should be inserted through the bunghole to stir 

 the insecticide. The insecticide should always be stirred before any 

 is taken out for spraying. It is convenient also to nail a small piece 

 of tin on one side of the bunghole which will act as a spout and 

 cause the insecticide to run into the measuring bucket instead of down 

 the side of the barrel. A hole also can be bored in the head about 1 

 inch from the edge on that side of the barrel which is opposite the 

 bunghole. A faucet or molasses gate should then be inserted in the 

 hole, and the barrel placed on its side with the faucet next the 

 ground. The bung should then be removed to permit stirring and 

 entrance of air. A stick can be used for this purpose. The best 

 way to mix an insecticide is to draw off several buckets full through 

 the faucet and pour back through a funnel in the bunghole. 



SPRAYING PROCEDURE. 



HOW TO APPLY THE SPRAY. 



In spraying for the control of white flies and scale insects the 

 method of application is the same whether a barrel pump or a power 

 outfit be used. The object should be the complete wetting of both the 

 upper and lower surfaces of the leaves as well as all the limbs and 

 the trunk. 



In applying the spray the operator should begin on the far side of 

 the tree and work around to the point nearest the machine. The 

 second half of the tree should be handled in like manner. If two 

 operators are at work on the same tree they should both begin at 

 the point farthest from the machine and proceed until they meet. 



The spray should be applied to the tree in a systematic way. The 

 operator should begin at the base and work to the top, inserting the 

 rod among the branches so as to spray the center of the tree. The 

 entire tree may be thus sprayed in sections, the operators proceeding 

 alternately from the bottom to the top and from the top to the 

 bottom. To prevent kinks in the hose, the operator in moving from 

 tree to tree should never make a complete turn. In case kinks appear 

 they should be immediately taken out by turning the spray rod and 

 not by pulling the hose. In pulling kinks out of hose the hose fabric 

 is destroyed. Such an avoidable waste of property should not be 

 permitted. 



PRESSURE. 



The pressure that should be maintained depends to a considerable 

 extent upon the agility of the man using the rod. If a man moves 

 rapidly, a greater pressure can be maintained without accompanying 

 loss of material than when a man moves slowly. A slow man will 

 not be able to handle a much greater pressure than 150 pounds,
