New YorK AGRICULTURAL EXPERIMENT STATION. 303 
The effect upon the trees and scales was practically uniform. 
There was no evidence of injury in any of the orchards except 
on Long Island where the fruit buds of the Japanese plums were 
very slightly injured, due in all probability to the late date of 
treatment. In all cases the foliage was delayed for about a week 
but was uniformly as good or better than that of the check trees. 
All of the treated trees, with the exception above noted, bore 
a fairly good crop of fruit which was practically free from scale, 
only an occasional fruit being found that showed any evidence 
of the insect, while the fruit of the untreated trees was, as a rule, 
badly disfigured and unmarketable. 
The effect upon the scale was none the less pronounced. ‘The 
check trees in all the orchards showed an abundance of living 
scales on both the old and new growth, while on the treated 
trees only an occasional living scale was found. In every case, 
also, the immediate and secondary effects of the wash were ap- 
parent, the former being due to the soluble ingredients, as shown 
by the experiments with the infested apples, and the latter by 
the slowly soluble or insoluble compounds. 
The wash adhered to the trees much better than was antici- 
pated. All of them remained white for at least two months and 
several showed the white color plainly throughout the season. 
As would be expected, the comparatively rough bark of the apple 
trees held the wash much longer than the smoother barks of the 
other kinds. ; 
Taken together the results are remarkably uniform and all 
point to the same conclusion, namely, that the lime, sulphur and 
salt wash is a safe and efficient remedy for the San José scale. 
But, although the fact that the experiments were conducted in 
different sections of the State and under somewhat different con- 
ditions, may make the results of more weight than if they had 
been confined to one or two orchards, it should be borne in 
mind that they represent but one season’s experience and hence 
cannot be considered final but only indicative of the value of the 
insecticide.
