Leaf Curl of the Peach. 



(Exoascus Deformans — Berk, FcJc). 



When we took this disease in hand, a number of trees in Mr. Peart's 

 orchard had succumbed to the continued defoliation. On our first visit 

 to Mr. ISTickell's, we found a team of bullocks pulling the trees out, 

 and on asking the reason, were told that the trees were of no use, as 

 they bore no fruit, and were gradually dying. The rooting out was 

 stopped on our advice, and with the happiest results. 



Cutting from a Pear Tree which was not sprayed. 



Mr. Peart wrote on the 11th January, 1914, that peach and apricot 

 trees sprayed with verdigris were quite free from curl, as were those 

 which had been sprayed with copper soda. Bordeaux mixture did not 

 give quite such good results as the two previous sprays, and lime sulphur, 

 though it cleaned all lichens from the trees, was not a success as far as 

 the " Leaf Curl " was concerned.
