GOOSEBERRY MILDEW 435 



been introduced as mildew proof, only to suffer the same injury 

 as previous sorts after a few years of general trial. The Ameri- 

 can varieties are not wholly exempt from its attacks, but are 

 much less susceptible, and seldom suffer serious injury. 



Remedies. Numberless remedies against the disease have 

 been suggested. No less than fifteen of these have come under 

 the writer's observation, most of which were reported successful 

 in greater or less degree. Among them, mulching with sea 

 weed, salt hay, green grass, tan bark, stones, tin cans, boards, 

 etc., is most frequently mentioned. This does aid in many 

 cases, as it helps to keep the soil cool, but it cannot be depended 

 upon to afford immunity. There is now a perfectly satisfactory 

 remedy known, and it is possible for anyone who is willing to 

 give the matter proper attention to grow the English goose- 

 berries in this country. Experiments inaugurated by Professor 

 Arthur, while connected with the Geneva (New York) Experi- 

 ment Station, and since carried on by others, have proved that 

 potassium sulphide (liver of sulphur), used at the rate of half 

 an ounce to a gallon of water, will hold this disease completely 

 in check. Experiments with Bordeaux mixture indicate that it 

 is also effective, though not equal to potassium sulphide. The 

 potassium sulphide is cheap, effective, easily applied, and does 

 not injure the plant nor render the fruit poisonous, hence is a 

 very satisfactory remedy. It is best dissolved in hot water, 

 then diluted to the required strength. The first application 

 should be made when the leaves begin to unfold, and be 

 repeated at intervals of two to three weeks, or after each heavy 

 rain thereafter. As the injury to the plant seriously inter- 

 feres with its growth, thereby lessening the succeeding crop, a 

 thorough treatment just after the fruit is gathered is likely to 

 prove of great value.
