232 STATE BOARD OF AGRIICUI/TURE. 



During September and October some time was spent in the giving of 

 advice against the Hessian fly in the field and a demonstration of para- 

 dichlorobenzene was started against the peach tree borer. This treatment 

 for peach tree borers seems to be successful so far as one can judge at 

 the present time. 



Some time was also spent during this period in the corn fields of Wayne 

 county in carrying on an educational campaign against the European 

 corn borer. 



The first two weeks in September were spent in preparing for and 

 attended the State Fair at Detroit, where an effort was made to exhibit 

 noxious insects and to demonstrate their control. 



Later a trip was made through part of the northern part of the Lower 

 Peninsula to collect information on the recent grasshopper outbreak and 

 to confer with the County Agents on any insect troubles they might have. 



After this the time has been occupied with the winter meetings and 

 talking on insect control up to April 1, 1922. These meetings were well 

 attended in all cases. 



REPOKT OF EXTENSION WORK IN FARM CROP>S. 



by j. f. cox, prof. of farm crops; g. w. putnam, specialist; h. c. rather, 



specialist; d. f. rainey, specialist. 



The demand for extension work has increased to the extent that it is 

 not possible to meet all requests for service with the staff available. The 

 careful development of leading projects has, we believe, led towards 

 greater eflflciency in work perfomied. 



Mr. G. W. Putnam was placed in charge of the general crops extension 

 projects April 1, being transferred from the position of Crops Experi- 

 menter, assigned to the Upper Peninsula. The alfalfa and legume cam- 

 paigns begun last fall have occupied a large part of his time. Mr. Putnam 

 is also in charge of the direction of the field inspection work of the 

 Michigan Crop Improvement Association, and the release of new varieties 

 from the College increase plats. 



With the resignation of Mr. A. L. Bibbins, January 1, 1922, to become 

 Manager of the Seed Dept. of the Grange League Federation Exchange 

 of Syracuse, N. Y., Mr. H. C. Rather was elected Secretary of the Mich- 

 igan Crop Improvement Association and placed in charge of the crops 

 varietal standardization i>roject. The close co-operation with the Farm 

 Bureau Seed Department has greatly increased the influence of the Crop 

 Improvemeut Association. 



Crop demonstrations and varietal tests, handled by Mr. D. F. Rainey, 

 have proved to be of great value in aiding in the dissemination of crop 

 varieties act'ording to adaptations. In many counties, the alfalfa cam- 

 paign work is made jiarticularly effective, due to the presence of carefully 

 planned alfalfa demonstrations planted one or two years before. 



The demand for crop exhibits at County Fairs, the State Fair, and the 

 International Grain and Hay Show, required considerable preparation
