tised soda-bordeaux, hj-drate-bordeaux, and potash- 

 bordeaux. The spraying began June 2d, and ten spra}^- 

 ings were applied during the season. The applications 

 were made with a knapsack pump, and therefore were 

 far more expensive than they would have been if the 

 sprayings were made with horse-power. With the 

 fungicide costing $5.00 per acre, and a machine that 

 would spray two or more rows at a time, it would be 

 possible to reduce the cost to $10.00 per acre, or even 

 less. In effedtiveness the soda-bordeaux stood first. 

 Between the other fungicides there was but little dif- 

 ference. The best results showed a redudtion of rust 

 of about one-quarter, which is not as satisfa(5tory a 

 result as had been expedted. 



In the spraying work condudled by Professors G. 

 E. Stone and R, E. Smith, at the Massachusetts Ex- 

 periment Station, the results were more encouraging. 

 The solutions used were potassium sulfid, saccharate 

 of lime, and bordeaux mixture. The spraying was 

 done with a knapsack sprayer, provided with a Ver- 

 morel nozzle, and after the first application it became 

 evident that the pradtice was of little importance on 

 account of the difiiculty in making the solution stick 

 to the plant. For successful spraying of asparagus a 

 finer nozzle is required than any that is now in the 

 market. 



In some other experiments carried out on a small 

 scale the asparagus plants were pradtically covered 

 with solutions, when they were put on with an ordi- 

 nary cylinder atomizer, and the lime solutions showed 

 excellent sticking qualities; but with the ordinary 

 coarse nozzle the solutions would run off of the glossy
