Exoascus deformans. By G. Zauli {Bull. R. Soc. Tosc. Ort. 11. 

 1907, p. 325). — Professor Vittorio Peglion, after showing that Exoascus 

 is the prime cause of the peach-tree disease, gives an account of some 

 experiments which he performed. The time at which the fungicide can 

 be most beneficially applied corresponds with that of the opening of the 

 buds. The washing should be applied before this period, at least a week 

 or two before vegetation begins. In moderately rainy regions a single 

 washing is enough, in very rainy regions two or more. Where two 

 washings are applied, it should be done when the tree is resting. The 

 mixture advised to be used is composed as follows : 



Copper sulphate 2 kilos. 



Quicklime 1 „ 



Ammonia chloride '200 „ 



Water 100 



The Professor treated a tree so far gone in disease that it had been 

 ordered to be cut down ; the tree had, as a result, retained nearly all its 

 foliage, whereas, in others not so treated the Exoascus caused all the 

 leaves to fall ; plants only half-treated showed the complete efficiency of 

 the treatment. Those treated fruited most prolifically, while the 

 accustomed falling of the fruit did not occur. — W. C. W.
