Agric., Trenton, 1891, pp. 349-357. Describes Peronospora viticola as affect¬ 
ing grapes in New Jersey; also black rot. Gives method of prevention, ad¬ 
vocating spraying with Bordeaux mixture. (J. F. J.)

and Exper. Sta., August, 1891, announcing the successful use of carbonate 
of copper [3 oz. per 50 gallons of water, 1 pound of ammonia], (D. G. F.)

sulphate of copper, Bordeaux mixture, modified eau celeste; and directions 
for treatment of black rot of grapes, pear scab, pear and apple leaf blight,

459. Chester, F. D. The leaf blight of the pear and the quince. Bull. Delaware Col¬ 
lege Agric. Ex. Sta., Newark, No. 13, July, 1891, pp. 16, pi. 2. Describes 
disease caused by Entomosporium maculatum and gives results of com¬ 
parative tests of modified eau celeste, Bordeaux mixture, precipitated 
carbonate of copper, ammoniacal carbonate of copper, carbonate of cop¬ 
per and carbonate of ammonia as preventives of pear leaf-bliglit. Re¬ 
ports modified eau celeste as giving best results, 85.1 per cent of sound fruit 
being picked from trees sprayed with it, as opposed to 84.4 for Bordeaux, 
80.8 for precipitated carbonate of copper, 78.3 for ammoniated carbonate of 
copper, 66.3 for carbonate of copper and carbonate of ammonia mixture, 
and 42.0 for untreated. Records injury to foliage and russet appearance to 
fruit caused by use of the ammoniated carbonate of copper mixture, and 
also failure of combined treatment of ammoniated carbonate of copper, and 
carbonate of copper and carbonate of ammonia mixture to effectually pre¬ 
vent the quince leaf-blight caused by the same fungus. Mentions success¬ 
ful treatment of 1,000 pear trees at Milford, using Bordeaux mixture as pre¬ 
ventive of the leaf-blight. (D. G. F.)

After giving an account of losses from the disease, quotes from Galloway and 
Scribner as to the fungus, Fusicladium dcnditricum, and also from former’s 
report of experiments in prevention of disease; gives results of experiments 
in Canada with fungicides as preventive. Concludes from comparative tests 
of copper carbonate in suspension in water, ammoniacal solution, copper 
sulphate and ammonia, copper sulphate dissolved in water, and hyposulphite 
of soda, that the copper carbonate in suspension gave the best results, even 
exceeding in efficacy the ammoniacal solution; that the copper sulphate, and 
ammonia and copper sulphate dissolved in water injured the foliage, while 
the hyposulphite of soda showed no effects because experiment was ruined 
by leaf crumpler. Gives formulae for preparation of fungicides and direc¬ 
tions for treatment and also method for home preparation of copper carbon¬ 
ate. Discusses treatment of grape mildew ( Pwonospora viticola) and goose¬ 
berry mildew. ( Spliairotheca rnors-uvce, B & C.) (D. G. F.)
