THE ROSARIAN'S PEST CALENDAR. 



BY MR. H. R. DARLINGTON. 



Precautions to be taken and Enemies to be sought for 

 throughout the Year. 



N.B. These notes have been compiled (except as to a few alternative 

 receipts for Copper Solutions ) from the directions given by the joint 

 Authors of the " Enemies of the Rose." 



MID** WINTER. 



To destroy Fungus Spores- 

 Drench the Rose plants with 



i.) Copper Sulphate : i-oz. to 2-gals. of water (see page 

 18, note (3) ), 



or (ii.) Bordeaux Mixture : 



Copper Sulphate . . . . 4-ozs. 



Lime . . . . . . . . 2^-ozs. 



Water . . . . . . 2 gallons 



or (iii.) Cupram : 



Carbonate of Copper .. .. i-oz. 



Liquid Ammonia . . . . 4~P mt 

 Water . . . . . . 2 quarts 



For use add 10 gallons of water. The advantage of 

 Cupram is that it is liquid and does not clog the syringe 

 and is less hurtful to plants than Copper Sulphate alone. 



FEBRUARY. 



To destroy Wintering Larvae- 

 Spray with Paraffin Emulsion. 



Dissolve IO-QZS. soft soap in one pint boiling water ; 

 add 5-ozs. paraffin, and stir vigorously. For use, dilute 

 with 10 volumes of water. 



MARCH. 



Search for green larvae of Sawflies (see pages 33-39). 



Clear away and burn all prunings from plants that have suffered 

 from fungus disease or insect attacks. 



Spray with Arsenate of Lead (see page 68, note (4) ) to destroy 

 Winter Moth, Tortrix Moth, Grubs, &c.
