in the treatment of black rot of grapes. Proc. 11th Ann. Meeting Society for the 
Promotion of Agricultural Science, Indianapolis, Indiana, August 18,19, 1890, 
pp. 59, 60 (issued December, 1890). Give result of experiments in Virginia 
to test comparative efficacy of Bordeaux mixture, ammoniacal solution of 
copper carbonate, copper carbonate in suspension, and combination of Bor¬ 
deaux mixture and ammoniacal solution of copper carbonate, three treat¬ 
ments of the former, five of the latter. Conclude Bordeaux to have saved the 
largest per cent of fruit, but ammoniacal solution to be most economical. 
197. Garman, H. Some strawberry pests; the strawberry leaf-blight fungus. Bull. 31, 
Kentucky Ag. Ex. Sta., December, 1890, Lexington, Kentucky, pp. 3-13. 
Describes disease with figures giving results of careful experiments with 
Bordeaux mixture, eau celeste, liver of sulphur, and London purple as pre¬ 
ventives. Concludes Bordeaux, applied at intervals of two weeks after re¬ 
moval of berries, most effective in prevention of Ramularia Tulasnei, Sacc., 
eau celeste standing second, and London purple, although better than no 
fungicide, standing last. Thinks the removal of diseased leaves in summer, 
if not followed by fungicidal applications, more injurious than beneficial, 
because lessening shade to young leaves.
