Spraying Experiments in Nebraska

At Beatrice (table 43), there was little difference in the 
efficiency of the two fungicides except in the control of blotch. 
Again Bordeaux proved superior to lime sulphur for this purpose. 
However, the difference in efficiency was only about 11 per cent. 
There was practically no difference in the amount of spray injury 
on the fruit. Here dry weather followed each application. 
There was more injury to the foliage from using lime sulphur than 
Bordeaux. The damage to foliage noted on the lime sulphur plats 
greatly resembled that of the Bordeaux plats in that there were 
the same characteristic brown spots on the leaves. However, 
the spots were larger and more irregular. In addition, the 
leaves were burned at the edges and at the tips.

No blotch or rust was present. 
At Lincoln (table 44), there is little evidence in favor of either 
fungicide except in injury to the foliage. Here lime sulphur did 
more damage than Bordeaux. The weather at this place was 
dry after each application.
