Putrefactive Mildew of Cabbage and Cauliflower- 



The moist season is very favorable to the development of various 

 diseases, and es})ecially so in market gardeners' seed beds. Mr. Geo. 

 Massee, of the Kew Gardens, P^ngland, describes a method in the 

 Journal of the Royal Horticultural Society, of pi'eserving tomatoes 

 and cucumbers grown under glass from the attacks of mould 

 fungi. This treatment is well worthy of trial by gardeners whose 

 young cabbage seedlings show the characteristic spotting and 

 blackening of the leaves due to the mildew f Pcronosjwr a parasitica) . 



The method is to commence watering the young seedlings Avhen a 

 fortnight old, every third day with one ounce of bluestone in 50 

 gallons of water.
