These poisons were combined with the summer strength of lime-sulphur 

 and three different applications were made. 

 Eesults were as follows: 



No injury could be determined from either of the poisons used and 

 there was little difference in the handling, mixing and weathering quali- 

 ties of the two poisons. 



PEACH SPRAYING. 



Spraying was done in a block of mixed varieties. Two applications 

 were made for fungous troubles. Eesults were computed from forty- 

 three varieties. 



Mixtures used were Atomic sulphur, 5 pounds to 50 gallons, self -boiled 

 lime-sulphur, 8-8-50, and hydrated lime and sulphur 8-8-50. The Atomic 

 sulphur was added to a small amount of water, thoroughly mixed with 

 it and then poured in the spray tank which contained the required 

 amount of water. Self-boiled lime-sulphur was prepared in the usual 

 manner. Hydrated lime and sulphur was made as follows: Eight 

 pounds each of hydrated lime and sulphur were sieved and thorouglily 

 mixed dry, then made into a paste by adding two gallons of boiling 

 water. Six more gallons of boiling water were added and the whole 

 mixture was stirred for five minutes and then cooled by adding 8 gallons 

 of cold water. Dry arsenate of lead was added to all mixtures at the 

 rate of ly^ pounds to 50 gallons for the first application only. 



All trees were given an application of strong lime-sulphur for leaf curl 

 and again on June 16th, all trees were sprayed with an application of 

 arsenate of lead and lime for curculio. On July 7th, the first spraying 

 of the three mixtures was made and the second and last application Avas 

 made on August 15, omitting the earlier varieties. Weather conditions 

 after tliis being very dry, further spraying was not considered necessary. 



Brown Kot was the only fungous trouble which made its appearance 

 to any extent and tabulated data on this is as follows :
