SPRAYING FOR FUNGI AND INSECTS. 



HE profits to the fruit grower of spraying his trees and plants as 



directed by professional experimenters appears to be of sufficient 



importance to induce every one of us to engage in it in real earnest 



during the year 1895. Indeed the benefits appear to be so decided, 



that no fruit grower can any longer afford to neglect the work. The 



monilia or fruit rot of the plum and cherry, the leaf-blight of the pear 



tree and the cracking of the pear, the apple scab and the Codling 



moth, all appear to have been fairly well controlled by spraying in 1894, 



according to the Report given us by Prof. Craig, at Orillia, last December. For 



instance, here are some extracts under the head of " Results": —

Cherries. 



The cherry suffers from the same diseases as the plum. The following are results 

 gained from two series af experiments in preventing '■ rot" on Yellow Spanish cherries : 



(1) Sprayed tree yielded 90 lbs. of fruit Unsprayed tree yielded 30 lbs. of fruit. 



(2) One selected sprayed tree yielded 130 lbs. of fniit, which netted $9.25. One 

 selected, equally good, unsprayed tree yielded 17 lbs. of fruit, which netted $1.20. 



Pears. 



Pear trees were sprayed to prevent " leaf blight " and the "cracking and spotting" 

 of the fruit. The best results gained showed that Flemish Beauty pears sprayed, yielded 

 75 per cent, more marketable fruit than those unsprayed. Beurre Giflard gave practically 

 the same results. ' The foliaige of the treated trees was vastly superior to that on trees 

 unsprayed. 



Apples. 



Apples were sprayed in several orchards, mainly to prevent injury from the fungns 

 causing "apple spot " and the depredations of the codling moth. 



The results gained show that the spraj-ed trees yielded 24 per cent, mort of first-class 

 fruit, 6 per cent. le*x of second-class and 18 per cent. It^s of third-class fruit than the same 

 number of trees unsprayed.
