6 MAINE AGRICUIvTURAE EXPERIMENT vSTATlON. I9I.4. 



O'f the partially opened buds were killed by frost. On June 

 2 considerable frost injury was noted on the young- leaves 

 throughout the orchards. By June 10 it was evident that a 

 large proportion of the flowers had failed to set fruit and were 

 falling oifT. As a result the crop obtained was only about 10 

 per cent of that harvested in 1912. 



EEEECT OE DIEFERENT SPRAYS ON THE EOEIAGE. 



On June 2 there was some evidence of spray injur}^ on 

 plot I, sprayed with bordeaux mixture, but the leaves on the 

 other plots were entirely healthy with the exception of the frost 

 injury mentioned above. A small amount of spray injury de- 

 veloped on plot I during the season but at no time was it 

 sufificient to do any appreciable damage or to cause any ma- 

 terial amount of leaf drop — 'a. marked contrast wiith the re- 

 sults ohtained in some of the previous experiments where bor- 

 deaux mixture was applied. The control of scab on the leaves 

 was almost perfect and better on this plot than on any of the 

 others. 



Plot 2, sprayed with lime-sulphur 20 per cent stronger than 

 standard dilution, showed some leaf injury from the spray but 

 this was very slight and somewhat less than was observed on 

 plot I. In this case, however, the injury did not appear 

 until after the second application of the spray. Scab control 

 on the leaves while not equalling that where bordeaux mixture 

 was used, was better than that on all of the remaining plots. 



Plot 3, where standaM dilution lime-sulphur was applied, was 

 practically free from leaf injury throughout the season, al- 

 though a little was noted. Scab on the leaves was fairly well 

 controlled, but more in amount than on plot 2. This began to 

 appear about June 10 or later. 



Plot 4, treated the same as plot 3 except that the first appli- 

 cation of lime-sulphur when the flower buds were showing 

 pink was omitted, agreed in appearance with plot 3 throughout 

 the season as far as the condition of the foliage was concerned. 

 The control of scab seemed to be as good in one case as in the 

 other. 



Plot 5, where "Soluble sulphur" was applied, presented a 

 marked contrast with the other plots where fungicides were
