FUNGUS ON VEGETABLE LEAVES. 



I inclose a few sample leaves from 

 my tomatoes, parsley and lettuce. 

 What is the trouble and the remedy for 

 it? They seem to have mildew and 

 mold on them, which is spreading. I 

 have used potassium gas for white hy 

 and I am now about rid of the pest, 

 except a big crop of the eggs. How 

 can I destroy the eggs? H. C. B. 



There is no method for the destruc- 

 tion of white fly eggs. The only thing 

 to be done is to wait until the eggs 

 hatch and then fumigate with potas- 

 sium cyanide several nights in succes- 

 sion. 



The fungus on the leaves generally 

 follows an attack of white fly and is 

 familiarly known as sooty mold. It is 

 not parasitic on the leaves, but never- 

 theless the plants are seriously in- 

 jured from the commercial standpoint. 

 When the white fly is under control 

 the fungus will gradually disappear.

DISEASED ONION TOPS. 



I have a bench of onions in my green- 

 house and am writing for information 

 about them. The onion tops drop over 

 and wither, some perhaps an inch or two 

 from the top, others halfway down and 

 others, again, at the bottom. The point 

 is clearly defined between the sound and 

 diseased portion. I have examined for 

 insects, but can detect none. Although 

 I have grown onions for years, I never 

 have had this experience before. 



E. S. P. 



There is undoubtedly some trouble 

 with your soil, which can be best rem- 

 edied another season by sterilization. 

 Growers of lettuce and other vegetable 

 crops nearly all sterilize, and find that 

 this ensures clean, thrifty plants.
