Befers to value of treatment with fungicides for prevention of rust. Concludes it is only 
indirectly beneficial and advocates grubbing up diseased plants. (J. F. j.) (See No. 970).

Describe treatment of black rot of grapes giving details of experiments made at Vienna, 
Va., to determine: ( 1 ) Best means of applying preparations; ( 2 ) relative value of Bordeaux 
mixture, ammoni ical copper carbonate solution, copper carbonateimsuspension, and a mixed 
treatment of the first two; (3) actual cost of each treatment; (4) amount of copper found on 
fruit. The amount of fruit saved by the various treatments varied from 93.61 per cent to 
99.20 per cent. The expense varied from .0077 cent to .008 cent per pound of fruit. The con¬ 
clusion reached was that of the three treatments that with ammoniacal solution was the 
most profitable. Give also report on diseases of the grape in western New York, the special 
object being to investigate “blight” or “ rust.” Give characters of disease with causes and 
suggestions lor treatment. Underdraining and late pruning arc suggested. Brief reference 
to other diseases. (J. F. J.)

Give details of experiments on pear leaf-blight and scab with five different fungicides, 
viz: Bordeaux mixture, ammoniacal solution, copper acetate, mixture No. 5 , and copper car¬ 
bonate in suspension. The first two gave the best results, the Bordeaux mixture being 
considered the better. For pear scab the experiments indicate that the sprayings should be 
made very early and that JBordeaux mixture is most to pe relied on. (J. F. j.)

Tests numerous compounds of copper as to their adhesive power when applied to the 
foliage of the potato as shown by analyses of treated leaves before and after submittal to 
artificial showers of rain. Concludes that Bordeaux mixture (2 kg. cop. sulphate and 1 k«\ 
lime) adheres better than the same mixture with double amount of lime; that the copper 
soda mixture and copper acetate possess adhesive power double that of Bordeaux, and the 
Perret mixture (copper sulphate, lime, and molasses) showed remarkable adhesive proper¬ 
ties, while Bordeaux mixed with clay (aluminium compounds) did not adhere so well as the 
standard Bordeaux. (D. G. F.) (See also Comp. Bend., Paris, Feb. 1 , 1892, pp. 234-236-

Gives details of experiments for the prevention of apple scab, using copper carbonate dis¬ 
solved in ammonia and in suspension in water; sulphur powder, and mixture No. 5 (ammo- 
niated copper sulphate and ammonium carbonate). The results were mostly negative, but 
mixture No. 5 was most efficient. Details of treatment of Septoria of raspberry 'and black¬ 
berry are given, and show that the foliage of the raspberry is too delicate to stand applica¬ 
tions of a corrosive nature. Foliage of blackberry is more resistant than raspberry and less 
so than that of apple. Ammoniacal copper carbonate solution can be used on blackberry 
but not on raspberry. The use of Bordeaux mixture for potato rot was successful. (J. F. J')

Gives an account of experiment to prevent apple scab undertaken to ascertain ( 1 ) compounds 
to be used; (2) time to make application; (3) compound best adapted to be used with insecti¬ 
cides, and (4) profit in spraying. Five fungicides were used, viz, ammoniacal copper car¬ 
bonate, modified eau celeste, dilute Bordeaux mixture, precipitated carbonate of copper, and 
ammonia copper solution. Of these dilute Bordeaux mixture gave the best results. Gives 
details of relative efficacy of fungicides, cost of spraying, effect of scab on the fruit, value 
of spraying to prevent scab, size of apples as effected by spraying, market value of apples, 
time and machinery for spraying. Found Paris green and dilute Bordeaux mixture together 
acted as both fungicide and insecticide. Discusses also spraying to prevent pear scab, dilute 
Bordeaux mixture and modified eau celeste being about equally beneficial, but the latter
