Pine needle scales are now hatching in central Illinois. The small scales 

 are in the crawler stage and are susceptible to insecticide treatment. Tiny white 

 spots on the needles are an indication of infestation. 



For control, use malathion, two applications at 10-day intervals, at the 

 rate of 1 quart of 50-57 percent emulsion concentrate per 100 gallons of water. 



Caution : Before applying insecticides, read the labels carefully and fol- 

 low all precautions. This not only will insure personal safety, but will also elimi- 

 nate insecticide residue hazards.
