Effect on the Fruit. 



In all the orchards treated, the fruit sprayed with the 

 several lime-sulphur mixtures was smoother and more highly 

 colored than that sprayed with Bordeaux mixture. The Bor- 

 deaux russeted the fruit of the Ben Davis so that it did not 

 have the finish required for fancy apples. A small per cent 

 of it had to be discarded as culls on account of the rough- 

 ened appearance due to the Bordeaux. The Yellow New- 

 towns were russeted considerably and the Winesaps only 

 slightly, while the York Imperial showed practically no rus- 

 set effect. 



The lime-sulphur sprays caused no russeting, or at most 

 very little where the strongest mixtures were used, and the 

 fruit sprayed with these mixtures was smooth, clean and 

 well colored. 



Experiments in Michigan. 



Similar experiments were conducted at Douglas, Mich., 

 in cooperation with the Bureau of Entomology, and the re- 

 sults of that work were much the same as those obtained in 

 Virginia. However, the injury to apple foliage by the com- 

 mercial lime-sulphur (2 to 50) was rather more severe in 

 Michigan than in Virginia. On the Wagener variety the 

 scab disease was held down to 4.8% of the crop by the com- 

 mercial lime-sulphur and arsenate of lead, to 3.6% by Bor- 

 deaux mixture and 19% by selfj-boiled lime-sulphur, while 

 81% of the unsprayed fruit was scabby. It appears, there- 

 fore, that the lime-sulphur solution is as effective in controll- 

 ing apple scab as Bordeaux mixture, while the self-boiled 

 wash is not so good in this connection. 



Conclusions. 



The writer feels that the information at hand is not 

 quite sufficient upon which to base final conclusions and rec-
