overwintering female will now hatch, and the young scales will move to the leaves 

 to suck sap. At times, infestations may be heavy enough to kill twigs and branches - 

 even entire trees. Apply a malathion spray (1 quart of 50- to 57-percent emulsion 

 concentrate per 100 gallons of water) in early July (central sections) after the 

 eggs have hatched. 



CAUTION: BEFORE APPLYING INSECTICIDES, READ THE LABELS CAREFULLY AND FOLLOW ALL 

 PRECAUTIONS. THIS WILL NOT ONLY INSURE PERSONAL SAFETY, BUT WILL ALSO 

 PREVENT RESIDUE HAZARDS.
