In the case of fusiform rust, which is one of the 

 major damaging agents for both loblolly pine and 

 slash pine, the most promising control measure 

 appears to be the development of more resistant 

 planting stock through genetic improvement. 

 Better control of reproduction weevils in pine 

 plantations will also require planting delays or 



treatment of seedlines with insecticides. Preven- 

 tion of losses from fomes annosus root rot will 

 require control measures such as chemical treat- 

 ment of stump surfaces after felling. For the many 

 bark beetles that plague the southern pine, salvage 

 currently appears to be the most practical form ot 

 control.
