back all young canes in the spring to within six or eight 

 inches of ^ the ground exactly as if a new plantation had been 

 made. No flowers will then be produced and in consequence 

 the moths will have nowhere to lay their eggs and there will 

 be no fruit in which the young larvae could feed. The 

 following year the plantation should be almost free of the 

 pest. 



J4) In small gardens it is quite possible to keep the pest 

 1 in check by picking off the shoots as soon as they begin 

 to wither in the spring, destroying the pink grub inside. 



(5) Spray Formulae. 



(ai) Paraffin Emulsion, winter strength. 



Paraffin Oil ' 1 gallon 



Soft Soap ... l-2 Ib. 



Water 10 gallons. 



Dissolve the soft soap in about a gallon of boiling 



water, remove the solution from near the fire and, while 



( still hot, add the paraffin. Churn the mixture very 



' thoroughly by syringing it back into itself. When 



required for use add soft water to make 10 gallons and 



mix again thoroughly so as to make sure that there is no 



free paraffin floating on the surface. 



(b) Lime Wash. 



Best Quicklime 10-15 Ib. 



Water 10 gallons. 



Obtain only best stone quicklime and store carefully 

 to prevent it from air-slaking. Builder's lime, which is 

 often partially air-slaked, should not be used. 



Slake the lime with a little water, and when slaked 

 into a fine powder, add the remainder of the water, stirring 

 vigorously the whole time. Strain carefully before filling 

 the spraying machine and keep the lime-wash well agitated 

 throughout the application. 



(c) Lead Ar senate. 



Lead Arsenate paste 1 Ib. 



Water 15 gallons. ; 



In mixing lead arsenate it is best to work up the 

 paste first into a thin cream with a little water, subse- 

 quently adding the remainder. 



(d) Paris Green. 



Paris Green paste 1 oz. 



Quicklime ... 1 Ib. 



Water, ..10 gallons. 



Slake the lime to a cream with a little water and 

 make it up to nearly 10 gallons with water. Then work 

 up the Paris green with a little water and add it to the 

 mixture of lime and water, stirring well before use. The 

 quantity of lime used has been increased considerably 

 ' above the normal in order that a better coating over the 

 shoots may be obtained.
