per sulphate and the Hme-sulphur wash on 

 dormant vines, and Bordeaux and soda Bor- 

 deaux at intervals during the growing sea- 

 son. 



The following substances were used 

 agaiinst the San Jose scale : The lime-sul- 

 phur wash (unboiled), the kerosene-limoid 

 mixture, the Carlson mixture, and Pratt's 

 Anti-scale Remedy. 



The first round of experiments and de- 

 monstrations, as announced in the May 

 issue of The Horticulturist, was held as fol- 

 lows: April 13. at Mr. Murray Pettit's, 

 Winona ; April 14, at Mr. Ambrose Pettit's, 

 Grimsby; April 15, at Mr. R. Kelly's and at 

 Mr. Bartlett's, Beamsville; April 17, at Mr. 

 J. Fretz's, Jordan ; April 18, at Mr. George 

 Robertson's and Mr. Pay's, St. Catharines ; 

 April 19, at ]\Ir. Jas. Hutchison's, Virgil ; 

 April 20, at Oueenston ; April 21, at Niagara 

 Falls. 



On account of the large extent of terri- 

 tory to be covered the owners of the vine- 

 yards and orchards in which the experiments 

 were conducted were asked to provide facili- 

 ties for the preparation of the chemicals 

 used, such as hot water or steam, a kettle, 

 two or three barrels, and a small amount of 

 lime, sulphur, and copper sulphate. The 

 owners were also asked to have the grape 

 vines cleaned of old bark. 



The spraying operations for the remain- 

 der of the summer will be directed mainly 

 against the grape rots. It is hoped that the 

 results will indicate (i) the proper time to 

 apply the Bordeaux, (2) the number of ap- 

 plications which will be necessary for the 

 production of clean grapes, (3) the most 

 effective sprayings of the season's opera- 

 tions, and (4) those sprayings Avhich may 

 be omitted with safely. 



The bluestone application (four pounds 

 to 40 gallons of water), according to the 

 Ohio authorities of doubtful value, is made 

 in the spring while the vines are dormant,

first week in June when the new growths 

 are from 12 to 18 inches long, the second 

 Bordeaux (B2) after blossoming about the 

 first week in July, and subsequent applica- 

 tions at intervals of 10 days or two weeks. 



The accompanying chart of the experi- 

 mental vineyard at Mr, Murray Pettit's will 

 show clearly the varied nature of the appli- 

 cations and the information which we may 

 hope to get from the experiments. Mr. P. 

 W. Hodgetts, B. S. A. of the Department of 

 Agriculture, has consented to act along with 

 me in carrying out these experiments, and 

 he will probably conduct the July and 

 August experiments. 



Barnyard manure, made chiefly from 

 grain and hay, is not well balanced in ferti- 

 lizing ingredients for strawberries.
