DISEASES OF PLANTS. 



Notes on fungus diseases for 1904, <i. 1'. Clinton | ( 'om lecticut State Sta. Ilj>t. 

 1904, pi. /'. pp. 311-828, pis. 11). — In a previous report (E. S. R., 16, p. 62) the author 

 gave notes on all the fungus and bacterial diseases and physiological troubles which 

 had been observed on cultivated plants in Connecticut. In the present report notes 

 are given on those which were prominent during the year or which were observed 

 for the first time. The arrangement is alphabetical by host plants. 



Among the diseases and fungi which are reported upon for the first time, the 

 occurrence of the secidial Btage of the asparagus rust is noted. The presence of the 

 rust parasite. Darluca JUum, is mentioned, and the same fungus is said to attack the 

 carnation rust and the blue-grass rust. The occurrence of the downy mildew, 

 Peronospora parasitica, on cabbage is noted; a id in a discussion of the brown rot of 

 cherries, caused by Sclerotinia fructigena, the author states thai from his observations 

 the fungus apparently spreads each spring either from the mummied fruit or infected 

 branches, and does not travel down the diseased pedicle- and from these infest the 

 fruit spurs. 



The powdery mildew of grapes is said to have been exceedingly troublesome, par- 

 ticularly to thin-skinned and white varieties. Notes are given on a bacterial disease 

 oi mulberry, which is reported for the first time in the state, causing more or less 

 injury to young trees in the nursery. This disease, which is due to Bacillus cubom- 

 < i n us, destroys the twigs, and frequently the whole tree becomes stunted and yellow- 

 ish in appearance. Thorough pruning of the trees in the winter time is recommended 

 as probably the besl treatment. The effect of frost injury on peaches is described. 



An account is given of a disease of potatoes, which is probably of bacterial origin, 

 and the possible relationship between this disease and the -oft rot of the tubers is 

 discussed. Mention is made of the black spot, or canker, of tobacco, and the must. 

 which is ot fungus or bacterial nature, hoth diseases occurring in the curing house.
