THE NEW RHUBARB CULTURE. 



Late in the summer, a blight or "spot" disease attacks 

 the leaves, causing brown, blistered patches to appear on 

 the foliage. Finally the leaves are perforated with holes, 

 as the substance wastes away. This blight seems unable 

 to do any harm when the plant is in full vigor, but 

 makes its attack as soon as the growth becomes feeble. 

 Sickly hills, or those on dry ground are first affected. 



Stalk Injured by Curoulio. 



Sometimes the line of attack will show quite plainly in 

 a field, where the progress of the spotting is stopped by 

 the resisting power of plants on a strip of moister soil. 

 Spraying with bordeaux or carbonate of copper mixture 

 would probably check or prevent the spotting and thus 

 somewhat prolong the growing season. But growers 

 assume that the blight comes too late to do much harm 

 to the next year's crop, and spraying is not attempted.
