250 MINNESOTA STATE HORTICULTURAL SOCIETY. 



Nursery Legislation in 1917. 



F. L. WASHBURN, STATE ENTOMOLOGIST, UNIVERSITY FARM, ST. PAUL. 



The amendment to the Horticultural Inspection Law is now 

 a law, passed by the legislature recently adjourned. This enables 

 the entomologist to better combat White Pine Blister Rust and 

 other dangerous insects and plant diseases when occasion arises. 



He is also authorized to shut out from Minnesota trees, 

 plants or shrubs from states infested with insects and diseases 

 new to Minnesota. 



In virtue of this authority we have just issued the following 

 quarantine notice dealing with White Pine, Stone Pine, Limber 

 Pine and all other five leaf pines. 



State of Minnesota 

 Office of the State Entomologist 



Quarantine Notice No. 1 White Pine Blister Rust. 



The fact having been determined by the Federal Horticul- 

 tural Board, the Bureau of Plant Industry and state authorities 

 that a dangerous plant disease, known as White Pine Blister 

 Rust, exists in the states of Maine, New Hampshire, Vermont, 

 Massachusetts, Rhode Island, Connecticut, New York, New Jer- 

 sey, Pennsylvania, Ohio and Wisconsin, affecting white pine, 

 limber pine, stone pine and all other five leaf pines, and since we 

 are endeavoring to stamp out this disease in the limited area in 

 which we believe it occurs at this time in Minnesota, and since 

 it may be introduced into Minnesota through shipments of nurs- 

 ery stock of the above varieties from infected states, an absolute 

 quarantine is hereby established prohibiting the shipment into 

 Minnesota from the aboye named states of any and all species 

 of five needled pines. 



Until further notice the foregoing quarantine shall become 

 and be effective on and after April 30th, 1917. 



This quarantine is established under the authority con- 

 ferred on the State Entomologist by the amendment to Chapter 

 206, laws of 1913, said amendment having been passed by the 

 State Legislature at its 40th session.
