Concerning the russeting of fruit due to spraying, differ- 

 ent varieties showed quite different results. As to sprays, the 

 Bordeaux gave the greatest percentage of injury. The com- 

 mercial lime-sulphur mixtures on the whole gave an average 

 of russeted fruit not greater than the unsprayed trees, while 

 the self-boiled lime-sulphur gave a little more. Individual 

 trees, however, occasionally" showed an unusual percentage 

 of russeted fruit, which amounted to very evident injury, but 

 usually in such cases the injury was of the nature of a scald- 

 russet, being on the side of the fruit and of the tree most 

 exposed to the sun. 



With the Bordeaux, the injury to the fruit from russet- 

 ing was even more severe than the injury to the foliage. The 

 least injury was in the Jones orchard, where the trees were 

 only sprayed twice with the 2-4-50 strength. At the Smith 

 orchard the Pound Sweet showed over 89 per cent of the 

 fruit russeted as against very little or none on the check trees. 

 At the Rog'ers orchard the average on the Bordeaux Bald- 

 wins was over 42 per cent, against about 12 per cent on the 

 checks. The average per cent of russet on all the Baldwins 

 sprayed everywhere was about 43 per cent, against about 20 

 per cent on all the checks. This russeting was frequently so 

 conspicuous as to amount to a serious injury. If we leave 

 out of consideration the benefit derived from the arsenate of 

 lead, the Bordeaux in our experiments did on the whole more 

 harm than good. Of course, this was a somewhat exceptional 

 year in this respect, but we certainly would recommend that 

 where Bordeaux is to be used on apples in this state in the 

 future, only the spraying on the young unfolding leaves be of 

 the 4-4-50 strength, and that the subsequent sprayings be not 

 stronger than 2-4-50. 



Not all the russeting of apples this year ivas due to the 

 spraying, as there was an average of over 18 per cent on ?)Z 

 check trees. On a few unsprayed trees only did this russeting 

 run very high or become serious in character. The unusually 

 late frosts of May and early June seem to be responsible for
