Warren Stiles in Maine recommends that manganese sulfate be applied 

 about first cover at a rate of 3 lbs. per 100 gallons. If using a 

 Mn-contai ni ng fungicide, 2 or 3 applications are necessary with 

 timings about petal fall, first and second cover. Research find- 

 ings in other areas indicate that recommendations for correcting 

 Mn deficiency in apple; trees should also be effective for peach 

 trees .
