THE COMPLETE DORMANT SPRAY 

“Makes a Tree Outgrow Its Troubles” 
SCALECIDE—tthe complete 
dormant spray—is the safest 
and most effective means of 
getting rid of overwintering in- 
sects. It invigorates your trees 
and gives them a good healthy 
start for spring growth. 
Scalecide kills scale, red mite, 
aphis (delayed dormant), bud 
moth, case bearer, pear psylla, 
overwintering codling moth and 
many other pests. Scalecide also 
has an invigorating effect on tree 
growth that is unequaled by any 
other spray. Apply just before 
the foliage starts in the spring. 


‘Spray fruit trees, shade trees, 
small fruit, and shrubs with 
Scalecide 1 to 15 in the spring 
before the buds show green, pro- 
vided the temperature is not 
colder than 40°. On peach and 
pear trees fall spraying is prefer- 
able to control peach curl and 
pear psylla. 
Spray evergreens, euonymus, 
etc. with Scalecide 1 to 20 in the 
spring just before the new growth 
starts.
