with dilute lime-sulphur. Begin when the buds start and repeat every

When Pruning, if a cane is cut that shows discolored pith, it may 

 indicate the cane borer. Cut back to sound pith. Burn trimmings.

GENERAL TREATMENT FOR RASPBERRIES, BLACKBERRIES 



AND DEWBERRIES. 





spraying potatoes and strawberries. 



Cut out the Fruit Bearing canes after the last picking has been 

 made. This will lessen insect and disease troubles that may be har- 

 bored on the old canes and allow more room for the growth of the new 

 canes. 



Orange Rust may appear in May or June. It is easily identified by 

 the bright orange color on the under sides of the leaves. There is no 

 method of preventing this trouble. As soon as it is found, the bush 

 should be dug out and burned. If allowed to remain the disease will 

 spread and destroy many plants. 



Anthracnose, identified by the grayish spots on the canes (also on 

 leaves, but not conspicuous), is common in many berry fields. It does 

 not yield to spraying unless very frequently done with bordeaux mix- 

 ture and this may not be profitable. If desirable, make the first spray- 

 ing when the new canes are 6 to 8 inches high and repeat every two 

 weeks during the growing season. 



Cutting out and burning the old canes immediately after fruiting will 

 be of some benefit. In starting a new field, make a special effort to 

 secure healthy plants. 



"WoRMS^-' or "Slugs" might appear at any time. Spray with an 

 arsenical if early in season, but if near picking time, use hellebore or 

 pyrethrum. 



Cut out and bum gouty galls, tree cricket eggs or borers in stems.
