A dormant oil application in the early spring will assist in controlling certain 

 scale insects and overwintering red mite eggs. Purchase dormant oil and mix with 

 water according to directions on the label. A 2 -percent oil spray is sufficient 

 to control San Jose, Putman, and tulip tree scale. Do not apply when temperatures 

 are below 40° F. or if new growth is present. 



CAUTION: REMEMBER— READ THE INSECTICIDE LABEL AND FOLLOW ALL PRECAUTIONS CAREFULLY.
