Exp. Sta., Madison, 1892, pp. 138-141, figs. 2. 
Gives results ot a series of experiments with Bordeaux mixture of varying strengths. 
The treatment was successful, as shown by an increased yield and freedom from blight,

On pp. 11 and 12, under head of “ horticultural division,” mentions favorable results of 
experiments with fungicides to prevent apple scab, peach and plum rot, pear and plum 
leaf-blight, and potato blight and rot. No details are given. (J. F.J.)

States that spraying apple trees (Wythe variety) with London purple, followed by a fungi¬ 
cide, caused, after a second double spraying, the leaves to fall from many trees. Ben Davis 
apple was not injured by a similar treatment. Vines sprayed with various solutions of 
sulphate of copper and sulphate of iron varied in their loss of fruit by black rot from 10 
to 80 per cent. The best remedy was considered to be 2 pounds of sulphate of copper, 
pounds of carbonate of soda, and 1% pints of ammonia to 40 gallons of water. Believes the 
latter might be increased 50 per cent. (J. F. J.)

lumbus Hort. Soc., vol. vi, Columbus, Sept., 1891, pp. 93-96. 
Gives a statement of the work of the station to prevent fungous diseases and destroy 
insect pests. Notes that a dilute Bordeaux mixture (4 pounds of lime and 4 pounds of copper 
sulphate to 50 gallons of water) was as effective in preventing apple scab, leaf-spot, etc., as 
the old formula of 6 pounds of copper sulphate and 4 pounds of lime to 22 gallons of water. 
Claims the former is better for several reasons. Considers Bordeaux mixture gave the 
best results of any fungicide used, the dilute form giving as good effects as the other for 
many diseases. (J. F. J.)

Discusses the subject from the points of hygienic treatment and the use of fungicides, lay¬ 
ing special stress upon good and clean cultivation. Describes the method of preparation of 
various fungicides, giving addresses of firms supplying chemicals, with prices. Mentions 
also methods of application of fungicides, and gives addresses of manufacturers of spraying 
pumps. Cautions the farmer against an unwise use of the fungicides, and details some 
experiences of those who have used the remedies recommended. In the concluding pages 
discusses various sorts of smut, those affecting oats, barley, wheat, corn, rye. and onions, 
giving directions for using the hot-water treatment [of Jensen]. The plate illustrates the 
forms of smut affecting various grains (J. F. J.)

years in the treatment of plant diseases and the prevention of insect injuries. Considerable 
space is devoted to a discussion of spraying from a hygienic standpoint. (B. T. G.)

Refers to idea that this treatment will prevent rust, but does not believe it will be at all 
efficacious. States that difference in climate causes a difference in length of time the seed 
should be treated for smut, being longer in warm than in cold climates. Believes sprinkling- 
grain before immersing in hot water preferable to soaking. Iu his ‘ improved method” the 
basket with the hot grain is placed for two minutes in a closed box. It is then spread on the 
floor and stirred for some minutes with a rake. Believes it would be best not to sow grain 
until four days after treating. (J. F. J.)
