The aim of this trial was to observe the effects of Biomin Copper on the defoliation
of a particularly difficult variety of peach, MayGlo.  Phoscare was used in conjunction
with the Biomin Copper as it has been shown to be very effective.

Leaf counts show that the use of Biomin Copper alone resulted in 80% of branches
having 100% defoliation and the remaining branches having 93% defoliation.
