Diseases and Pests. The persistence and long life of the lilac under conditions 

 of neglect is sufficient evidence of its resistance to disease and insect pests. 

 About the only thing which could be considered as troublesome is scale. The 

 Oj^ster Shell and San Jose scale both sometimes affect the plants. This trouble 

 may be detected by thv characteristic gray and slightly elevated scales. To 

 eradicate such a condition, the i)lants sliould be s))rayed in very early spring, 

 prior to the appearance of the new leaves. Use citlier kerosene emulsion or a 

 strong mixture of Black Leaf 40 (tobacco juice) and whale oil soap. It is 

 understood that the young pests hatch out in June, and it is wise to again 

 spray at that time if the ailment lias been previously noted.
