l'i<;. 399. Ax INDIVIDUAL TREE IN ORCHARD OF H. L. BROWN, WATERPORT, 



N Y. 



PRUNING 



In pruning we prefer the single stem method. We thin out the 

 top and head back for the first two or three years; then discon- 

 tinue to head back, just keeping a good, well-thinned head. 



INSECT ENEMIES 



The borer and curculio are the two most injurious enemies of 

 the quince. Dig out the borers. For the curculio spray with 

 arseiiate of load, four pounds to fifty gallons of water; or jar 

 tlio trees, catching the insects in a canvas or other suitable re- 

 ceptacle. 



The quince Lecanium, a scalelike insect, is sometimes trouble- 

 some ; this we treat in the dormant state with oil emulsion, one 

 gallon to fifteen gallons of water. 



DISEASES 



Leaf spot and fruit spot are controlled by either a lime-surphur 

 or a bordeaux spray, of the same strength as that used for apples.
