3. Mildew. This will be found the worst of the 

 three enemies of the Rose here dealt with, and the most 

 difficult to overcome. It appears as a white mould on 

 the foliage of Rose plants, and if not promptly 

 checked will spread from one plant to another over the 

 whole collection. There are few, if any, gardens 

 entirely free from this disease, although in some it is 

 much more troublesome and persistent than in others, 

 and more particularly in the autumn. By those who 

 may not have the means of spraying the plants with the 

 preparations mentioned on page 22, it may be kept in 

 check with flowers of sulphur. The simplest way to 

 apply this remedy is to lightly dust the sulphur over the 

 whole of the affected plants, by means of a fine muslin 

 bag, on the first calm evening after it is detected, and 

 to repeat the dusting at intervals as may be found 

 necessary until the mildew has disappeared. 



There are two golden rules which should be kept in 

 mind when waging war against the above insect and 

 fungoid pests. The first is to look out for them early, 

 and on their first appearance to at once take the 

 necessary means for their destruction. The second is to 

 persevere with the remedy adopted until a cure has been 

 effected. 



In order to give the beginner confidence, I may add 

 that by following the foregoing instructions, and keeping 

 strictly to the two golden rules I have here laid down, I 

 have for many years kept my own collection of over 

 two thousand Rose Plants free from all fungoid and 

 insect pests throughout the year. Had I only had the 

 assistance of this little book and adopted the preventive
