Discusses article by Berlese and Sostegni in September number (see No. 801) expressing 
the opinion that the reaction taking place in the soil upon the addition to it of copper sul¬

ably that the copper sulphate behaves like sulphate of potassium or sulphate of ammonium.

Gives results of experiments in treatment of Peronospora viticola in various localities in 
France testing the following fungicides: (1) Bouillie bordelaise celeste [principally sulplio- 
saccharate of copper]; (2) Bouillie celeste a poudre unique [Sulphosaccharate of copper 
mixed with sulphate of copper and carbonate and bicarbonate of soda 2 kg, per hectolitre of 
water]; (3) Bouillie au sulphate d’ammonique [Bordeaux mixture; l kg. copper sulphate + 
500 gr. lime -f- 400 gr. ammonium sulphate -f 1 hectolitre of water]; (4) Bouillie bordelaise 
au sporivore Lavergne [Bordeaux mixture with addition of sporivore 1 kg. 500 gr. copper 
sulphate, 1 kg. 500 gr. lime, to which is added 1 kg. of sporivere, prepared by M. Lavergne, 
heated previously in 1 hectolitre of water]; (5) Bouillie bourguignonne [1 kg. 500 gr. copper 
sulphate, 2 kg. 250 gr. sodium carbonate crystals in 1 hectolitre of water prepared warm]; 
(G) Bouillie berichonne [same formula with addition of 25 centilitres ammonia 22 per cent]; 
and (7) ordinary Bordeaux [1 kg. 500 copper sulphate, 500 gr. lime in 1 hectolitre of water.] 
Although the results of the several experiments varied somewhat the author concludes that 
the mixtures containing a small amount of copper in solution as Nos. 1, 2, 3, and 6 gave no 
better results than those containing the copper in insoluble form. Reports from use of No. 3 
serious injury to the foliage. Decides that the ordinary Bordeaux mixture using only 1 kilo¬ 
gramme of copper sulphate per 100 litre of water is not strong enough to prevent severe at¬ 
tacks of mildew. Closes with accounts of favorable results obtained with use of sulplio- 
steatite. (D. G. F.)
