Table II shows: First, that the total yield by weight, and by 

 bunches, of the sprayed row was nearly three-fourths more than 

 that of the unsprayed row; second, that the prime bunches from 

 the sprayed row were more than double the prime bunches 

 obtained from the unsjjrayed row, while the culls from the un- 

 sprayed exceed the number of culls obtained from the sprayed 

 row. The same conditions hold in values. These results are 

 more marked when expressed in percentages. It should be 

 remembered that each row represents one-fifteenth of an acre; 

 from this it can be estimated that the total gain in value from 

 spraying an entire acre would have amounted to |132.75. 



The results brought out in the foregoing tables show distinctly 

 that spraying asparagus to prevent the rust (was not only a 

 decided benefit to the sprayed rows but also to the grower, the 

 value received for the increased yield being more than double 

 the cost of spraying. 



At the time of selecting the above field the growth was too 

 young to show any appreciable difference in the rows. The 

 three side rows were chosen as they could be reached with long 

 leads of hose from the side of the field and in this way avoid 

 driving over them. Later in the fall the indications were that 

 the three sprayed rows had been in better condition previous to 

 spraying than any of the unsprayed portion of the field. This 

 difference may all have resulted from the spraying. In order to 

 eliminate the advantage which outside rows usually show, the 

 middle row of the sprayed belt was selected for keeping record
