THE CODLING MOTH 



the tree. Generally the blossoms all point outward; therefore, 

 the spray should be driven down from the top, in from the side, 

 and up from the bottom of the tree. The hose should be long 

 enough to do the work readily and strong enough to stand the 

 pressure. It is best to use a seven-ply hose. The spray rod 

 should be a ten-foot bamboo pole. It should be fitted with a cut- 

 off valve at the base and with a drip ring and 45 degree angle at 

 the nozzle end. (See Figure). The cut-off should be used to 

 save spray material while passing from tree to tree. The nozzle 

 for the early spraying should be one that gives a driving, fan- 

 like spray, which will not break into a mist until it has left the 

 nozzle for at least five feet. The spray used is arsenate of lead 

 about three pounds of paste or one and one-half pounds of 

 powder to fifty gallons of water. Care must be taken to keep the

mixture constantly agitated so that the arsenate of lead will not 

 settle to the bottom. The spray should be applied three to five 

 days after the petals begin to fall, with the sole object of filling 

 each calyx cup with the poison. It makes no difference if it 

 touches the rest of the tree. "It is not a question of how much 

 you spray, but of how well you spray." 



A second spraying, similar to the first, should be applied ten 

 days later. This will complete filling the calyx cups that are not 

 open as early as the first spraying. These sprayings usually 

 cannot be done at one time as a number of the cups are closed 

 before others are open. If the calyx cup is closed it is too late 

 to apply any spray for the first brood. In applying the spray, the 

 outfit stops just before the men spraying the orchard reach a 

 point opposite the center of the first trees of the first two rows
