Apple Tree Decline Survey

Apple decline research is hindered by an incomplete understanding of where it is occurring and what its symptoms look like on different rootstock/scion combinations. Please consider taking this survey, even if you haven't observed apple decline in your orchard blocks! Your participation will help drive research focus in the right direction and aid in the creation of informative extension documents.
