1892, p. 5, fig. 2. 
Quotes from report of Secretary of Agriculture in relation to value of ammoniacal copper 
carbonate solution for pear leaf-blight. Preferable to Bordeaux mixture because about as 
effectual and cheaper. Costs cents per tree for Bordeaux, against 2J cents per tree for 
copper carbonate solution. (J. F. J.)

Discusses the use of fungicides containing copper and the liability of danger from use of 
fruit sprayed with them, concluding that there is really more copper in many articles com¬ 
monly eaten than is found in sprayed grapes. (J. F. J.)

Directions for treating Monilia fructigena. Burn leaves, etc., in autumn; spray before 
buds open in spring with iron sulphate, and after flowers open spray with sulphide of potas¬ 
sium. (J. F. J.)

States that Bordeaux mixture will prevent blight of potato, as may also ammoniacal solu¬ 
tion of copper carbonate. Doubt expressed as to whether it will pay to treat vines. (J. F. J.) 
793. [Anon.] Rot among late potatoes. <Wm. Farmer, 10th ser., vol. x, Baltimore, 
Aug. 1, 1891, pp. 170-171, f col. 
Recommends early planting and harvesting for prevention of rot. Bordeaux mixture and 
other copper compounds, together with London purple, will prevent the disease and kill in¬ 
sect pests at the same time. Article quoted from American Cultivator. (J. F. J.) 
794. [Anon.] Scabby pears. <Cult. and Country Gent., vol. lvii, Albany, N. Y., 
Jan. 21,1892, p. 47, ^ col. * 
Query as to cure for scabby pears answered by saying that fertilizing and manuring will 
not be effective. Spraying with copper solution has been tried, but without positive results.

vol. ii, Sydney, Sept., 1891, p. 557. 
Mentions the report of the British consul at Bordeaux, in which a reference is made to this 
subject. Says that numerous scientific analyses were made showing that the amount of 
copper in wine made from sprayed vines was so small that human health could not be injured 
by it. Another investigation was made a few months ago and confirmed this result. (M. V.) 
796. [Anon.] Sulphate of copper and the potato disease. <^Gard. Cliron., 3d ser., vol.

States that experiments concluded last year by the Agricultural Society are described in 
detail in their journal. The remedy has not prevented the disease, but has lessened its 
amount. Advises early planting. (M. B. W.)

Description of a machine designed for spraying with liquids or powders, sowing seed, and 
distributing manure. Gives account of tidal made with it. (M. V.)

<Agric. Gaz. N. S. Wales, vol. n, Apr., 1891, p. 
Notes tediousness of distributing sulphur on vines affected with Oidium by means of bel¬ 
lows, and says Strawsonizer sulphurs evenly and quickly, implying its value for sulphuring 
vines. (M. V.)

<Union and Advertiser, Rochester, N. Y., Jan. 27, 1892. 
Under the head of “Insecticides and fungicides” refers to successful use of Bordeaux 
mixture in combating plant diseases. Carbonate of copper considered a remedy for apple 
scab (Fusicladium dendriticum). Reference is also made to presence of sulphate of copper 
and blue vitriol on grapes and the little dauger from use of sprayed grapes. (J. F. J.)

Albany, N. Y., Jan. 28, 1892, p. 68,1 col. 
Gives results of preliminary greenhouse experiments with peas and tomato seeds grown 
in soil containing 1 to 5 per cent of copper sulphate. Finds germination accelerated by 
presence of sulphate but maturity also hastened and plantlets dwarfed. Reports analyses 
from soil of old potato field showing presence of copper in distinct quantities. Concludes 
that nearly eleven hundred years would be required to impregnate to the extent of 1 per 
cent a layer of soil 1 foot deep by ordinary methods of spraying usually employed. (D. G. F.)
