EXPERIMEXTAL FARMS 



7 GEORGE V, A. 1917 



TREE FRUITS 



Large fruits were, as a general rule, below the average in quantity. The earlier 

 varieties produced an average yield but the fall and winter varieties were disappointing. 

 This was, no doubt, larg-ely due to the unfavourable weather conditions prevailing 

 during the blossoming period. Three sprayings only were given during the season, 

 the early or dormant spray being missed. All of these sprays were of lime sulphur 

 and lead arsenate with the exception of some experiments in which Bordeaux mix- 

 ture and arsenate of lead were used. They were made in the following strengths 

 at the period stated : — 



First spray when leaf clusters were showing green — 



Lime-sulphur gallons. 3 



Lead arsenate pounds. 5 



Water gallons. 100 



Second spray when the petals of flower blossoms had fallen — 



Lime-sulphur gallons. 2J 



Lead arsenate pounds. 5 



Water gallons. 100 



Third spray two weeks later — 



Lime-sulphur gallons. 2 J 



Lead arsenate pounds. 5' 



Water. , gallons. 100 



Fruit was remarkably clean notwithstanding the favourable condition for fungi 

 development. Insects, excepting aphis, gave but little trouble. The aphis were quite 

 prevalent but were easily controlled by application of Black Leaf 40, 1 pint to 100 

 gallons of water. This was, in our case, mixed with lime sulphur and applied during 

 the last two sprayings. 



The following experiment was again conducted this -year to determine the 

 relative efficiency of Bordeaux mixture and lime sulphur. Standard strengths were 

 used in all cases. 



SPRAY EXPERIMENTS. 



Lime Sulphur versus Bordeau Mixture. 



These results, considered along with those of last year, conclusively show that 

 cleaner fruit is obtained when lime sulphur is used than when Bordeaux mixtui'e is 

 applied. This is applicable to this section of the province in particular.
