DISEASES AND INSECT PESTS 223 



the bloom is out, but if the practice is continued until 

 the buds swell, and if a final spray with some mild 

 insecticide is carried out just before flowering, little 

 trouble from this pest need be feared. When syringeing 

 use lukewarm, rain or soft water. 



Pests are no respecters of varieties, and, from the 

 common Dog Rose of the hedgerows to the latest 

 speciality of our catalogues, all are liable to attack. 

 Rust and mildew, it is true, spread quicker on the 

 leaves of some varieties than others, but the bush which 

 suffers most is that which is in poor condition. Attend 

 to cultural details, and each bush will be strong, healthy, 

 able to bear attack, and sturdy enough to suffer no ill 

 effects from insecticides and fungicides. 



Don't fancy that because the foliage is attacked the 

 flowers will not suffer ; if one part is "ill" or injured 

 the rest of the plant cannot be in the best of health. 

 Watch for the first signs of disease and attacks from 

 pests ; immediately take stringent measures to prevent 

 the trouble spreading, and in this way keep the bushes 

 clean 1
