 trees of the Uano variety, Lincoln orchard, Bcntonville, Ark., 1906. Fruit picked 

 September 6. 



Bitter-rot was not so severe on the Gano as it was on the Jonathan 

 trees, but the crop on some of the unsprayed trees of the former 

 variety was scarcely worth picking. As seen in Table 2, 99.32 per 

 cent of the crop from 6 Gano trees was free from the disease, while 

 only 32.16 per cent of sound fruit was obtained from the 3 checks.

In Table 3 the results from the treatment of tl^e Ben Bavis trees 

 are given, the 6 sprayed trees yielding an average of 96.9 per cent of 

 sound fruit and the 3 check trees only 7.05 per cent. Practically the 

 entire crop of the unsprayed trees was lost, while the sprayed fruit 

 suffered very little. This result is remarkably good for three appli- 

 cations, and such results can not be expected except after the most 

 thorough work.
