34 MONTANA EXPERIMENT STATION 



was learned from Mr. Keeves of the Bureau of Entomology that 

 the alfalfa weevil becomes inactive when the temperature falls below 

 (iO deo^rees F. A considerable amount of research along this line 

 liad lieen done by the Bureau. This served as a suggestion to the 

 ti nfercnoe that the salt grass might be raked, stacked, baled, and 

 shipped with safety between October Tst and April 1st. provided 

 this was done only on days when the temperature fell below 60 

 degrees. After extended deliberations the following resolution was 

 passed : 



Resolved, That the material known locally in Utah as "Salt Grass Pack- 

 ing" be admitted into the states now maintaining a quarantine against alfalfa, 

 straw, and other hay from Utah because of the presence of the alfalfa weevil, 

 provided that such material be cut only between the dates of October 1 and 

 April 1, and that the raking, shocking, stacking, baling and shipping of this 

 material, as a commercial product, be allowed only after the maximum daily 

 temperature of the season has fallen below 60 degrees F. 



Provided, further, that a certificate from the Crop Pest Inspector of 

 the State of Utah, showing that these requirements have been met, accompany 

 each shipment. 



Provided, further, that no salt grass packing shall be held over in the 

 field from one season to another. 



Be it further resolved. That the use of such salt grass hay as a packing 

 material in shipments of fruits, crockery, and other materials be permitted, 

 provided it has been cut and removed from the field between October 1 and 

 April 1, as above specified, and stored in warehouses renote from alfalfa fields, 

 alfalfa hay, or other suspected materials. 



Upon returning to Montana Mr. A. L. Strausz, State horticultur- 

 ist, and the writer recommended that our quarantine be modified to 

 agree w'itli the resolution and to cover new territory known to be 

 infested with the weevils and also to cover a change in the require- 

 ments regarding emigrants' movables, as recommended by the con- 

 ference. Tlie quarantine as now in force, therefore, reads as follows: 



QUARANTINE NO. 4 



WHEREAS, It has become known to me that an injurious insect, popularly 

 called the alfalfa weevil, and scientifically known, as "Phytonomus posticus," 

 exists and is dangerously injurious to alfalfa in the State of Utah, and in certain 

 counties in the State of Idaho, to-wit: Bingham, Cassia, Bear Lake, Oneida, 

 Bannock, Franklin, Power and Payette; and in certain counties in the State 

 of Wyoming, to-wit: Unida and Lincoln; and in a certain county in the State
