Potato Rot in Canada.
--The Perth (Canada)
It seems now to be beyond a doubt that the potato rot has made its appearance, and is likely to prove very destructive in this section of Canada
We are informed that in some localities entire fields are turning black, and there are but very few patches but show indications of being effected.
It is consequently impossible to tell at this stage of the disease what the extent of its ravages may be, but it is confidently stated that at least one third of the present year's drop will be destroyed.
The season has been very wet, scarcely a day passing without rain, more or less, and the wet, cold weather may have had something to do with producing the reappearance of the potato blight.
