446 EXPERIMENT STATION RECORD. 



closely resembling that occurring on beet leaves. There appears to be 

 some difference in the characteristics of the two, but the variations 

 arc thought to be within the limits of a species, and their probable 

 identity is pointed out. 



Experiments with eggplants (pp. 304-307). — Four varieties of egg- 

 plants were sprayed with different fungicides for the prevention of 

 attacks of Phyllosticta hortorum. There was but little difference noted 

 in the effectiveness of the 4 fungicides used. An examination of many 

 of the roots at harvest time showed they were badly infested with 

 nematodes, in some places the galls being very apparent. 



Experiments with lettuce (pp. 307-309). — Sprayings were made with 4 

 fungicides on different varieties of lettuce, for the prevention of blight, 

 and it was found that the early sprayings of all the plants somewhat 

 injured them. There was very little blight present until the plants had 

 passed blooming. On this account there was no estimate made of the 

 amount of damage or of the efficiency of the fungicides. 



Experiments with beans (pp. 309-314). — Experiments were conducted 

 during 1S97 with beans on soil that had grown 7 or 8 successive crops, 

 the object being to test means for the prevention of pod spot and 

 bacterial blight, both of which have existed to some extent since 1894. 

 No appreciable amount of blight was present and in many cases the 

 application of the fungicides to the young plants had an injurious effect. 

 A second crop was planted July 31 and treated with fungicides the 

 same as before. There was no marked difference in the action of the 

 different fungicides, but the potash -Bordeaux mixture was slightly 

 better than the others. The effect of thinning pods as a means of pre- 

 venting disease was investigated and found to be without any appre- 

 ciable value. 



Crimson clover disease (pp. 314-319). — Notes are given of a crown 

 disease of crimson clover, due to Sclcrotinia trifoliorum. Desiring to 

 study the fungus in the field, a plat was sowed with different kinds of 

 clover and allied plants, the ground being strewn with the debris of 

 dead plants and adhering soil after the seed was sown. Of all the 

 clovers tested, the crimson clover proved most susceptible to the dis- 

 ease. The author states that there is nothing to indicate that the 

 disease may be transmitted by seed, but that a Held once badly infected 

 should be plowed and planted to other crops for a number of years. 

 The occurrence of another fungus, Polythrineium tri/olii, on scarlet 

 clover, is mentioned. 



Experiments with cucumbers (pp. 319-322). — Eight applications of 4 

 different kinds of fungicides were made on a number of varieties of 

 cucumbers, to test their efficiency in preventing mildew and anthrac- 

 nose. The anthracnose was not noticed on any of the plants during 

 the year. The other disease became quite abundant in September, the 

 plants sprayed with Bordeaux mixture and potash Bordeaux being less 

 affected than the others. An attempt was made to inoculate cucumbers 

 with an anthracnose of hops due to Colletotrichum sp., without success.
