For larger quantities :

At the end of this chapter will be found a list of 

 recipes for the diseases of roses. 



So the plants work on through the hotter part 

 of the summer and now towards its close the nights 

 commence to become cooler and the days are still 

 quite warm; the air itself is very moist and humid. 

 This occurs usually in the latter part of August, and 

 this change from eighty degrees or more in the day- 

 time to sixty degrees or less in the night is one which 

 the rose foliage does not like. When there is also 

 great humidity mildew is liable to occur. A good 

 remedy is grape dust, which can be obtained in any 

 seed store. Another fine remedy is a solution of 

 sulphide of potassium, one-quarter of an ounce to 

 a gallon of water, to which add one and one-half 

 ounces of common soft soap or one-half ounce of 

 Fels-Naphtha soap. The soap should be boiled be- 

 fore being added to the solution. Always spray early 

 in the morning, and if mildew has already appeared, 

 spray early in the morning after each heavy rain. 

 During the past year Bordeaux Mixture has proved 

 the best preparation for the prevention of mildew. 

 This may be purchased already mixed and with 

 directions for use, at any seed store.
