disease, together with recommendations looking toward its control, 

 have been prepared and published in " Special Crops," the official 

 organ of the ginseng growers. 



The work on several diseases is still under way. Although these 

 will not be completed for at least another year, it is expected that 

 v.-e will publish reports of progress on some of them. 



(d) The grape diseases investigation, of which ]\Ir. Reddick has 

 charge, is to be continued. By a cooperative arrangement with the 

 State Experiment Station, Mr. Reddick has charge of the disease 

 work in the Chautauqua Experimental Vineyard near Fredonia, 

 N. Y. He is here continuing his studies of the Necrosis of the 

 grape, and beginning work on the so-called " Black Knot "' and 

 Mildew. The experiments for the control of Black Rot have been 

 repeated again this season. In cooperation with Professor Wilson 

 of the Department of Horticulture, we have sprayed some 70 

 acres of grapes this season in a vineyard near Romulus, where the 

 work for 1908 was conducted. Mr. Reddick has had general charge 

 of the work, with Mr. C. N. Jensen^ assistant in the department, 

 constantly on the ground to look after the details. Owing to the 

 exceedingly dry weather, the results this season are not striking. 

 Generally speaking, there has been very little rot in the vineyards 

 of the State this year. However, there was sufficient rot in our 

 experimental vineyard to demonstrate again the efficiency of Boi'- 

 deaux mixture as a preventive if thoroughly applied and at the 

 proper time. Commercial lime sulphur appears to have given 

 equally as good results as Bordeaux. 



(e) The bean disease investigations have been continued by Mr. 

 Barrus, as in the previous season, on the farms of the Burt Olney 

 Canning Co., Oneida, N. Y. Here, again, the dry weather has so 

 entirely prevented the Anthracnose as to forbid the drawing of 

 definite conclusions as to the value of spraying for the prevention 

 of the disease. Seed from selected clean pods of last year's crop 

 was distributed in several localities in this State and elsewhere 

 to be tested for freedom from the disease. So far as reports show, 

 the crop grown from this seed is entirely free from the disease. 

 Particularly striking has been the result with this seed, which gave 

 a perfectly clean crop in Louisiana under conditions which gave 

 a badly affected crop from seed gathered in the ordinary way. 

 This season's results seem to establish beyond a doubt the value 

 of clean pod selection for the control of the Anthracnose.
