a soft l)rown rot appareiitly due to au undetermined fungus of the 

 PJiycomycetes or alga-like fungi. This occurred more commonly on 

 fruit hanging close to the ground or actually in contact with it. 

 In the latter case there was a surface growth of white liocculent 

 mj^eeliuni. The rot commenced as a discolored or water-soaked area, 

 soon becoming dull brown and spreading irregularly over the balance 

 of the fruit, accompanied by a heavy exudation of juice. 



Anthracnose {CoJletotrichum phomoides [Sacc] Chester). — Some 

 few eases of this disease on ripe fruits were collected. It caused 

 sunken, circular areas on the side or end of the fruit, often of con- 

 siderable size, in which appeared the pink (or in advanced cases 

 black) conidial masses. Of slight importance. 



Following cracks, insect and mechanical injuries or other wounds 

 bacterial soft rot was common. 



Root-Knot, Nematodes {Heterodera radicicola [Greef] Miill.) — 

 The losses due to the attack of this minute worm have been heavy 

 and much more in fact than is generally realized because of the 

 fact that it works below ground. Attacks by this parasite will ex- 

 plain to some extent, it is thought, the weakness of not only tlie 

 tomatos but of other crops permitting leaf and fruit parasites to 

 make headway in spite of spraying or other preventative measures. 

 In the Station plots tomatos sutfered most severely, but eggplant and 

 peppers were also attacked. At the end of the season examination 

 showed a lumdred per cent infestation of all varieties, certain ones, 

 however, maintaining growth in spite of the nematodes and even 

 giving a crop of fruit. 



Where death occurred, the first symptoms were a slight wilting 

 of the upper leaves, which increased until within a few days the 

 entire plant Avas involved and death ensued. Upon pulling a wilted 

 ])lant, the roots were found malformed or to consist of a series of 

 (enlargements or galls. Within these swellings the presence of the 

 parasitic worms or nematodes in various stages was easily demon- 

 strable with the microscope. Various fungi contributed to the death 

 of attacked plants and speedily rotted away roots and crown, liber- 

 ating a new brood of Avorms into the soil, so that in old eases nothing 

 remained but the woody tap root and fragments of secondary roots 

 and galls. The nematodes liberated in this manner remain in the 

 soil for a number of years and are (•ai)al)l<' of reinfesting any ucav 

 plants that may be set out. 



Certain varieties in particular of the second planting, namely, 

 Stone. Duke of York, ^latchless, and Beauty were practically de- 

 stroyed, tlie potting soil having been infested apparently. It was
