DESCRIPTION OF PLATE VT. 



Sprayed and unsprayed branches of Lovell peach trees in the experiment block at 

 Biggs, as they appeared in 1895. The sprayed branches at the left show the large 

 amount of fruit and healthy foliage on the sprayed trees; the unsprayed branches 

 at the right have lost most of their foliage and all the fruit from curl. These 

 unsprayed branches show the typical and common effects of curl. Hypertrophy of 

 the branch is not shown, and it is probable that these branches carry little if any 

 perennial mycelium. Thorough winter treatment of such Ijranches with proper 

 fungicides will prevent 98 per cent of the spring infections and conduce to the 

 development of foliage and fruit, as shown on the branches at the left. All these 

 trees were equally infected by the fungus in 1893, when the orchard suffered severely 

 from curl, and had the branches at the left not been sprayed before the leaf buds 

 opened in the spring of 1895, they would have been in the same condition as those 

 at the right of the plate. (Compare with Pis. I, V, and VII.)
