spring and continue at intervals. Spraying will not be very effective 

 if the disease is allowed to gain a foothold. 



Insict Pists. The rose beetle, the cockchafer, and the weevils 

 are complained of as enemies of the rose. 



The beetles and cockchajers eat the foliage and buds, and their grubs 

 devour the roots. The grubs can only be got at by hand-picking. 

 If grass turfs are placed upside down under the soil the grubs will 

 collect in them, and they can be picked off and destroyed. Nothing 

 but hand-picking can be resorted to for the beetles on the foliage 

 and buds. 



Weevils do harm by gnawing buds, foliage, and tender shoots. 

 They can be caught by placing sacking on the ground ; on the 

 approach of light they fall from the tree and shelter there during the 

 day, and so can be collected and destroyed. Vapor ite will kill the 

 larvae in the soil. 



Green Fly or Rose Aphis. This is one of the very worst of rose 

 pests. The lady-bird feeds on green fly, but in spite of this natural 

 check the roses become covered with aphis. Spraying must be done 

 with care or the tree will be injured. Carbolic sojt soap and water 

 is one of the best sprays, using about Jib. to 5 gallons of water. To 

 this may be added Ib. of quassia chips. 



Spray with nicotine wash for leaf -rolling Saw fly. The Rose Slug- 

 worm may be destroyed with nicotine or hellebore wash* 



A large number of caterpillars and moths feed on the foliage of 

 the rose. The best remedy is to spray with arseniate oj lead, early 

 in the year.
