The campaign to eradicate the common barberry, which was 

 started by the United States Department of Agriculture last 

 spring, has already met with gratifying results. The common 

 barberry harbors the black, or stem, rust of wheat, oats, barley, 

 and rye, a disease which causes enormous losses in this country. 

 In certain European countries it has been demonstrated that the 

 eradication of the barberry has resulted in a marked decrease 

 in the amount of damage caused by this disease. In central and 

 northwestern states where the campaign is being conducted, public 

 sentiment has been aroused. Nurserymen for the most part have 

 agreed to discontinue distributing common barberry bushes. 

 Park boards in many cities have eradicated them. State nursery 

 inspectors and state entomologists are destroying the bushes 

 wherever stem rust infection is found. Several state councils of 

 defense have issued appeals for the eradication of this barberry, 

 and the public safety commission of Minnesota has issued an 

 order providing for compulsory eradication in that state. The 

 Japanese barberry does not come under the ban, as it does not 

 harbor the rust.
