98 SPRAYING CROPS 



Remedy The raspberry is very sensitive to the 

 corrosive action of fungicides, and it must be sprayed 

 with care. Recent experiments at the Ohio Station 

 indicate that the dilute liordeaux mixture may be used 

 to advantage against this disease, although it is not a 

 complete remedy. Apply once before the leaves come 

 out, and two or three times afterward, though not after 

 the blossoms open. "Care should be taken to direct 

 the spray to the young growth, and avoid the old canes 

 after the first application." In Canada the recom- 

 mended treatment is to spray with copper sulphate 

 solution before buds burst, and with Bordeaux mix- 

 ture ten or fifteen days after leaves open, repeating 

 the latter soon after the old canes are cut out.
