342 REPORT OF THE DEPARTMENT OF ENTOMOLOGY OF THE 
TESTS IN ONTARIO COUNTY. 
The experiments were conducted in a small peach orchard 
near Geneva. It had been planted about four years but had 
become very badly infested with the scale. The trees selected 
for the experiments were encrusted on the trunks and larger 
branches. They were sprayed June 27 when the young leaves 
were well out. The weather at the time of treatment was fair 
with but little wind. Four trees were sprayed with the 
ammonia-resin- compound, Station formula, both strong and 
weak, with practically the same results as on Long Island ex- 
cept, aS was expected, that the young leaves were somewhat 
injured. Two trees were also sprayed with the California resin 
wash with practically the same results as on Long Island. In 
this case also the young leaves were burned somewhat. 
LIME-WATER-KEROSENE WASH.!° 
This wash was made after the formula given by Marlatt and 
prepared as directed by him in the bulletin above referred to. 
The formula and directions are as follows: 
Reesh. dimes. Say? oe ore ne ae eae 4 pounds 
Wiatler ie iat FCT ioe oe oe et ae ce 5 gallons 
Kerosene. >. cis sisi La Oe eee eee 1 gallon. 
“Slack the lime slowly with small quantities of water in order 
to get a creamy solution. When thoroughly slacked dilute to 
five gallons, add one gallon of kerosene, and churn until emul- 
sified (one or two minutes).” 
This mixture was applied with especial care. The tree was 
thoroughly covered. Considerable difficulty was experienced in 
applying the wash evenly as the oil separated from the water 
very quickly, and made heavy streaks on the trunk and 
branches. It remained white on the tree for a few days but 
soon turned a dirty gray and disappeared almost entirely in a 
few weeks. 
Results. The trees were not injured, and at the time of the 
final examination, August 7, the tree was nearly freed from the 
scale; the occasional surviving scales found evidently escaped 
being reached by the spray.
