of the experiments it appeared that different varieties of potatoes with- 

 stand attacks of these fungi to different degrees, Carman jSTo. 3 being 

 one of tbe most resistant, while Rose of Sharon was exceedingly suscep- 

 tible to disease. Details are given for the preparation and application 

 of the fungicides. 



Spraying in 1897 to prevent gooseberry mildew, 0, P. Close 

 {New York State Sta. Bui. 133, pp. 489-500, dgm. 1). — During the season 

 of 1897 potassium sulphid, Bordeaux mixture, lysol, and formalin 

 were tested side by side to determine their value for the prevention of 

 the gooseberry mildew. The fungicides were applied at three different 

 times, one lot receiving them just as the buds were opening, the second 

 plats eleven days later, and the last sections twelve days after the 

 applications to the previous sections. The first mildew appeared May 

 26 and by June 7 portions of the plantation were badly mildewed. At 

 this time lysol and formalin seemed to have been without effect. Bor- 

 deaux mixture was more effective but not as good as potassium sulphid 

 where the treatments were begun very early. The foliage was not 

 injured by any of the fungicides. The cost of the solution of potassium 

 sulphid, which gave the best results, was about O.J ct. per bush for 

 seven applications. The station recommends the use of potassium 

 sulphid solution (1 oz. to 2 or 3 gal, water) as the most effective fungi- 

 cide for the prevention of gooseberry mildew. The methods of appli- 

 cation are given in detail and the results of the treatment are tabulated. 



The general appearance of the fungus is described, and as a rule it 

 was generally found that the English varieties and their seedlings are 

 more subject to attack by mildew than the American varieties.
