HE foliage of roses is very frequently attacked 
by sawfly larvee, which feed upon the leaves and 
cause the bushes to become unsightly, or at least 
much less beautiful and ornamental. Three com- 
mon species eat the leaves of roses, and are well 
distributed and quite injurious over the United 
States east of the Rocky Mountains. 
These insects are easy to control. Knocking them 
some distance from the bush with a stream of water 
is a simple remedy. Since they eat the leaf tissue, 
thoroughly spraying the leaves with a stomach 
poison, such as 3 rounded teaspoonfuls of powdered 
arsenate of lead to 1 gallon of water, whenever the 
larve begin to appear, will kill them and thus pre- 
vent the injury.
