EXPERIMENT STATION RECORD. 



"(7) It seems that the thicker skiuned, darker colored varieties are better able to 

 resist the attack of the disease. 



"(8) Potatoes should not be allowed to remain in the ground long after ripening, 

 especially if the season is wet." 



Fungiroid as a preventive of potato rot, H. P. Gould {Maine 8ta. 

 Rpt. ]8f)5, %}]}. 78, 7.9).-^A test was made of Fungiroid, which is claimed 

 to be a powdered Bordeaux mixture and a substitute for that fungicide 

 as ordinarily prepared. In order to test the efficacy of this fungicide a 

 plat coutainiug 18 rows of potatoes was treated in the following man- 

 ner: The first row was sprayed with Bordeaux mixture, Fungiroid was 

 applied to the next, while the third was left untreated to serve as a 

 check. This order of treatment was preserved throughout the plat, 

 there being in all C rows sprayed with Bordeaux mixture, treated 

 with Fungiroid, and 6 checks. The first application of the fungicide 

 was made July 13, and 2 other applications were given at intervals of 

 about 2 weeks. 



The following table gives a summary of the experiments: 



Bordeaux mixture vs. fungiroid. 



From the above table it may be seen that Fungiroid, while slightly 

 increasing the yield of potatoes over that of the checks, seemed of little 

 value as a preventive of the disease. 



Gloeosporium myrtilli on Vacciiiium myrtillus, G. Wagner {Ztsclir. Pflanzen- 

 kraiik., 6 {1896), No. 4, pp. J9S, 199). — Notes are given of this new fungus described 

 by Allescher. It seems very injurious to its host.

 attacks Zizania latifolia, producing edible forms.

A new remedy for potato scab {Amer. Gard., 18 {1897), Xo. 116, p. 178). — Edi-

 of formalin as a preventive of scab. The seed tubers are soaked for 2 hours in a 

 solution of 8 oz. in 15 gal. of water.
