Corn-Ear Worm : Sometimes found feeding on the fruit of tomato. 

 (For description of larva, see insects affecting corn.) 



Flea-Beetles (Epitrix cucumeris) : This is the same flea-beetle that 

 causes injury to the potato, ft riddles the leaves of the tomato with 

 little holes, and injures the function of the leaf. 



For further description of this pest and treatment, see insects affect- 

 ing the potato. 



(Fungi.) 



Black Rot (Macrosporium tomato) : This fungus produces 

 roundish, black velvety areas on the fruit of the tomato. The spores 

 are many-celled, and sooty-colored, and are borne on threads covering 

 the diseased spots. Sometimes the leaves and stems are also affected. 



Treatment : Spray with Bordeaux, beginning when the flowers open, 

 and repeat at intervals of ten days or two weeks. 



Cut Worms (Agrotis ypstton). After Riley. 



Blight (Bacillus solanacearum) : This is a bacterial disease and 

 causes the death of the leaves. The bundles of the potatoes and stems 

 become brown or black. The disease is apparently spread to some extent 

 by insects. 



Treatment :' Keep potato beetles and flea-beetles in check with Bor- 

 deaux and Paris green. 



Leaf Spot (Septoria lycopersici) : Attacks the leaves, stem, and 

 sometimes the fruit. Angular spots containing minute black fruits appear 

 on the leaves and do considerable injury. 



Treatment : Spray with Bordeaux a week after transplanting, and 

 again at intervals of two weeks. 



Scab (Cladosporium fulvum) : Olive-brown, felt-like areas occur 

 on the under side of the leaves and brown discolorations on the upper 

 surface. In severe cases the leaves turn black, shrivel up, and die. 

 Tawny-colored, two-celled spores are produced on the clustered stalks 

 of the fungus of the under surface. 



Treatment : Spray with Bordeaux early and repeat at intervals of 

 ten days or two weeks.
