MILDEW 107 



for mildew that I know is to sprinkle the foliage with 

 flowers of sulphur, but as this is a longer operation and 

 not so effective I do not recommend it. If the plants 

 are given a fair amount of potash manure during the later 

 stages of growth and the houses are carefully ventilated and 

 not too much water splashed about the beds and paths, 

 mildew should not trouble growers to any serious extent, 

 though there are one or two varieties, such as Mdme. G. 

 Rivol and Mdme. Paolo Radaelli, that are very susceptible 

 to it. These plants should be given a spraying directly a 

 trace of mildew is discovered.
