INJURIOUS INSECTS OF I909 AND IQIO. 7a 
the roots of raspberries and other plants the well known swellings or 
galls. From its very nature it would be extremely difficult to con- 
irol when once established. All affected plants should be pulled up 
and burned. Only healthy nursery stock should be planted on land 
which has not recently grown raspberries or blackberries. From 
the most recent researches on this disease it seems possible that 
raspberries may become infected from affected apple trees. 
Lear Spot: Numerous small, light colored spots, with darker 
borders, often appear. In the center of the spots small black dots 
are often visible. Usually the disease is not serious, and the value 
of spraying is not known. 
Rust: The rust appears in its most conspicuous stage as bright 
red patches on the lower side of leaves, distorting and rendering 
them worthless. The fungus threads may live in the canes for a 
number of years, so that spraying is of value only in preventing 
spread to other plants. All affected parts should be removed and 
burned. 
Shrubbery. 
Plant lice often attack the leaves of shrubs, but any contact 1n- 
secticide, like a soap solution, or nicofume will keep them in check. 
“RED SPIDER”: These little pests are very bad in a dry season. 
Spraying with ordinary water will keep them in check. 
Squash. 
See Cucumber. 
Strawberry. 
Lear Spot: The common large leaf spot, with a purplish 
border and lighter colored center, is usually very prevalent. It may 
be controlled by spraying with bordeaux once before the blossoms 
open and once or twice after the fruit is picked. In the late fall or 
early spring, the leaves may be cut off and then burned. See Spray 
Calendar, page 174, for insects. 
Sweet Peas. 
Piant Lice: As in the case of shrubs the lice on sweet peas 
can be kept in check by soap solutions, tobacco products or ordinary 
water. 
Tomato. 
Worms: These are larvae of a large moth, often called hum- 
ming bird moth because of its habit of hovering over flowers and
