PROGRAM FOR INSECT AND DISEASE 
CONTROL OF RASPBERRIES 
1. When starting new plantings, use only plants which are as 
disease free as it is possible to obtain. 
Remove and burn old fruiting canes immediately after harvest. 
Remove and burn all portions of canes injured by tree crickets, 
borers, or other can insects when pruning in the spring. 
4. Dig and burn immediately, when foun, all plants affected with 
such diseases as curl, mosaic, and orange rust. 
5. Spray every spring when the buds show green with liquid 
lime-sulfur, 1 gallon in 8 gallons (one pint to one gallon) of 
water. 
6. Remove and burn all “handles’ or portions of the old cane from 
black and purple raspberry tip plants before planting. 
7. If leaf-ating insects appear early in the season, spray with 
lead arsenate; if later, when fruit is well formed, use rotenone 
or pyrethrum sprys. 
STRAWBERRIES 
Strawberries usually do not require spraying unless leaf spot 
diseases and leaf roller become serious. 
Strawberrie should not be planted on newly plowed land which 
has been in sod or which has remained idle for some time because 
of possible injury from white grubs. 
CURRANTS and GOOSEBERRIES 
The only insect of importance on currants and gosseberries is 
the current worm. Usually one application of a rotenone spray or 
dust when the worms first appear will be sufficient. 
SPRAY FOR RED SPIDER CONTROL 
Evergreens and Shrubs: Application of Miscible Oil. ¥% pint Oil 
to 3¥2 gallons Water with 4 to 8 teaspoons Nicotine Sulfate. Apply 
in the spring when the weather is above freezing. This should 
never be applied during the summer months as the oil has a ten- 
dncy to kill the needles. 
It may be necessary to use a summer application of Dritomic 
Sulfur: 5 lbs. Dritomic Sulfur to 50 gallons water. This should be 
only applied during the summer with the temperatures above 70 
degrees.
