fruit that was better color and smoother than trees spraj-ed with the 

 self-boiled lime-sulphur, or the Bordeaux, while the color of the finiit 

 sprayed with the self-boiled lime-sulphur was not as bright as where 

 the spraying was done with the commercial lime-sulphur. Trees sprayed 

 with Bordeaux mixture had a very good color on the foliage but not 

 as bright a color on the fruit. In experiments on peaches, the Bordeaux 

 mixture invariably burned the foliage, producing an effect much as the 

 shot hole fungus does. The commercial lime-sulphur burned the leaves 

 slightly and the foliage on trees that were sprayed with the self-boiled 

 was not injured at all. Owing to the dryness of the season, we were 

 unable to get any definite results on the rot or other fungous troubles. 

 The amount of this was so small in all parts of the orchard, that no 

 conclusions could be drawn. 



The method of applying this spraying mixture is undoubtedly un im- 

 portant factor in relation to the burning of the foliage. Where coarse 

 nozzles are used and trees are drenched, there is nearly always injury 

 done to the foliage and it seems highly desirable to use new fine nozzles 

 and make a light spraying. 



Respectfully submitted,
