study of the alkaline permanganate method for determining available 

 nitrogen might be completed. It is expected that active work will be 

 begun in the near future. 



MISCELLANEOUS. 



Two hundred thirty-nine samples of a miscellaneous character, includ-

REPORT OF INSECTICIDE AND FUNGICIDE INSPECTION. 



tL«I*JLS<-.«_, ... 



ANDREW J. PATTEN. 



To the state Board of Agriculture: 



During the year 1920, 73 samples of insecticides and fungicides have 

 been collected and analyzed. The sampling was done by Mr. E. A. He- 

 bard and the analytical work was performed by Mr. Glenn C. Forrester, 

 a graduate student from the University of Michigan. The results are 

 presented herewith. 



LIME SULPHUR SOLUTIONS AND SUBSTITUTES. 



Only two samples of lime-sulphur solution were collected, owing to the 

 fact that the inspection was not started until after the spraying season 

 was nearly over. 



Some attention was given to the filling of barrels and some complaints 

 of short measure were received. Several barrels of a shipment made 

 by" the Jas. A. Blanchard Co., St. Joseph, to the Berrien County Fruit 

 Exchange, Coloma, Michigan, were tested and found to be short from two 

 to four gallons per barrel. Owing to certain circumstances in connec- 

 tion with the case over which we had no control, no action was taken. 

 It is believed, however, that a repetition of the practice will not occur.
