Abstract
A quantitative evaluation of hypovirus treatment on the recovery of infected American chestnuts at West Salem, Wisconsin was made by monitoring 164 trees from 2006 to 2012. Survivorship of treated trees was better than untreated control trees for the period from 2008 to 2012, and the cumulative increase in survivorship was 20% by the 2012 tree census.
Survivorship of trees was influenced by initial tree size regardless of treatment, with larger trees surviving better than smaller ones.
Treated trees also grew faster than control trees in four of the six years. Hypovirus treated trees grew seven times faster than control trees from 2007 to 2008 and four times faster from 2010 to 2011.
