work bas been completed, and plan- have Itch outlined to preveni 
rein festal ion in those area- where barberry seed was distributed by 
natural agencies before the original bushes were destroyed. 
In Iowa and in States ea-t oi the Mississippi River, where infested 
area- exist in far greater numbers, many of them involving all un- 
cultivated land in entire counties, tin' status of the program is not 
?o far advanced. In Iowa, Wisconsin, Illinois, Missouri, Minnesota, 
Indiana. Ohio, and Michigan an intensive Burvey has been made of 
about <'•') percent of the counties needing attention. In these State-. 
as in those farther west, detailed records, Including map-, have been 
kept of all local ions w here barberry bushes were found, thus simplify- 
ing reinspections of infested area-. 
In Pennsylvania, Virginia, and West Virginia field operations have 
been restricted to the more important grain-growing valleys, and 
striking results have hern obtained in localized arc::- where bushes 
have been removed. These States are not subject to the sweeping 
wind- that frequently distribute spores for great distances in the 
Great Plain- region, and whenever bushes are destroyed there i- a 
marked reduction in the amount of rust that occurs the following 
year. 
Table 9 summarizes, by State-, progress in barberry eradication 
during the year.
