FRUIT 



Peach leaf curl is serious and is causing almost complete defoliation of unsprayed trees 

 in backyards . All we can suggest is to fertilize and water during dry periods, to promote 

 vigor and a new crop of leaves. The disease is easily controlled by a single, dormant 

 application of almost any fungicide. 



Fire blight is showing up on apple, pear, crabapple, hawthorn, and related plants. See 

 Report on Plant Diseases No. 801 for more details. 



Apple scab is now serious on apple and crabapple . Infected leaves are turning yellow and 

 are dropping off. Many trees will be nearly defoliated during the next several weeks 

 where a protective spray program is not followed.
