The White Pine Blister Rust. 



This disease, loinid on pines and, in one stage, on species of 

 Ribes (currant and gooseberry), has become such a menace to ottr 

 forest interests that not only has the Federal Florticultural IJoard 

 forl)idden the entry of all pines into this country from Furope, btit 

 is also considering a cpiarantine of areas in the United States already 

 infested. This is a matter calling" for the closest co-operation 

 between the Plant rathologists. the Forest Service, and the Nursery 

 and ( )rchar(l Inspection Services in the \arious states, partictilarly 

 in ihcjse states where lumber interests are represented. 



I'or four years we ha\e been watching a i)lanting of imported 

 ])ines in a .Minnesota nurser^• and. up to date, have not ol)scr\ed 

 the appearance of this disease. Nevertheless, we plan for the com- 

 ing season a careful survey of all nursery- stands of species of pines
