effective weapon. This method was used in the spring of 1923, an 
intense clean-up campaign being put on in Ashtabula County, north¬ 
eastern Ohio. 
Clean-up in Ashtabula County 
In the summer of 1922, federal scouts reported Ashtabula County to 
have the most com borer of any Ohio county. The highest infestation 
at that time was approximately one percent of the stalks infested in a 
few fields near the lake shore. However, no farmers had observed corn 
borers unless it was brought to their attention. The entomologists in 
Ohio felt that Ashtabula County alone, perhaps had enough corn borers 
to make the start in clean-up desirable. This took the form of a burning 
campaign, plans for which were made and carried out by the farmers 
themselves under the direction of the entomologists. The county farm 
bureau was the main organization used, and the county agent the leader 
of the project. The cooperation of the U. S. Department of Agriculture 
in conducting the campaign, and of the State Experiment Station in 
follow-up work during 1923, made it possible to cover the area effectively 
and to measure the results of the entire campaign. It was hoped that a 
thorough test of this method in this county would point conclusively to 
the value of burning in a subsequent campaign in 1924 over the entire 
area. 
The week of April 16th to 21st was set apart as publicity week, during 
which the Extension Entomologist and county agent appeared in the 
schools and at township meetings over the infested area in the county. 
Talks were given before 3620 people, and in this way homes were 
reached through school children which, as later found, proved to be an 
ideal method of impressing the parents. 
Newspaper articles were prepared and given to the papers to be 
released each day of the week. Each article pointed out one particular 
phase of the corn borer problem and how it depends upon spring burning 
for its solution. The cooperation of editors was secured in all towns. 
The drive was given publicity through editorials, and in one case, in 
large type across the bottom of the front page. 
Cartoons showing the need of spring burning, were prepared on lantern 
slides and these furnished to picture show houses within the area. 
This, together with the newspaper items and school visits, brought the 
matter to the attention of town residents who were asked to properly 
dispose of crop remnants in back yard gardens.
