fungicides used, 



Bordeaux mixture (ordinary), 1 to 11 formula, was used until 

 the last tvvo or three sprayings when potassium sulphide, 1 oz. to 

 2 gallons water, was substituted for it. This substitution was 

 made so that the fruit would not be spotted with Bordeaux mix- 

 ture at the time it was picked for market. 



Lysol and formalin were each used in three strengths, 1 oz. to 

 1 gal. water, 1 oz. to 2 gals, and 1 oz to 4 gals. ; and potassium sul- 

 phide in two strengths, 1 oz. to 2 gals, and 1 oz. to 3 gals, water. 



Applications of these materials were made with a bucket force 

 pump fitted with a Bordeaux nozzle. No injury was done to 

 the foliage by any of the solutions. 



OBSEEVATIONS AND DATES OF TREATMENTS. 



Tests in 1897. — The first spraying was made April 12 just as 

 the buds were bursting. This was followed by applications April 

 23, May 5, 17, 26, June 7 and 21. The bushes made a good 

 growth and had a good setting of fruit. Mildew was found in 

 small amounts on the fruit May 26. This developed rapidly on 

 the fruit and by June 7 had spread to the new growth. A careful 

 examination revealed less mildew on the bushes treated with 

 potassium sulphide than on the other treated or untreated bush'es. 



As it was desired to market the fruit green, the last spraying 

 was made June 21 and the fruit was picked early in July. 



Tests in 1898. — Owing to the very mild Aveather early in 

 March the buds began to open and by the middle of the month 

 were in condition for the first spraying. They were not sprayed, 

 however, because it seemed that cold weather must come and 

 check the premature growth, hence it would be useless to spray 

 until continuous growth might be expected. Contrary to expecta- 

 tion the latter part of March was not unfavorable to a slow growth 

 and by April 1 when the first spraying was made the growth was 

 about ten days in advance of what is desirable at the time of first 

 application. Later applications were made April 14, 26, May 9, 

 21, June 1 and June 13. There was an abundance of moisture
