Grape Anthracnose, Experiments in the Control of. By Lon 

 A. Hawkins (U.S.A. Dep. Agr., Bur. PI. Ind., Circ. 105 ; 1913). — 

 Grape anthracnose is due to tiie fungus Sphaceloma amfelinum, and 

 causes considerable damage in the vine-growing districts of the United 

 States. 



It attacks all the green parts of the plants, giving rise to cankers 

 on the stems, and brown spots, surrounded by a well-defined, circular, 

 bright-red zone, on the berries. Later the berries shrivel and die. 



The fungus winters on the mummied berries and on the old wood. 



The disease can be easily controlled by cutting out and burning 

 all diseased parts, by spraying the dormant vines with concentrated 

 lime-sulphur solution, one in ten gallons of water, and by spraying with 

 Bordeaux mixture (4-3-50, 4-2-50, or 3-2-50) five times : — 



[a) when the shoots are 8-12 inches long. 



[h) just before and after flowering, and tv/ice again at intervals of 

 from ten to fourteen days. — D. M.C.

Grape Leaf-Hopper, The. By F. Z. Hartyell (U.S.A. Exp. 

 Stn., New York, Bull. 359, Feb. 1913 ; 6 plates, 3 figs.). — 

 Spraying experiments during 1912 showed (i) that black leaf 40, 

 one part to 1600 parts water or Bordeaux mixture, is an efficient 

 spray for the leaf-hopper ; (2) that fruit from vines protected from 

 the hopper is superior to fruit from vines subjected to attacks from 

 this pest. 



Chemical analyses of grapes from sprayed vines gave a gain of 

 from 8 to 68 % in sugar over those from untreated vines, while the un- 

 sprayed grapes had o to 20'6 % more acid than sprayed grapes.
