Biocontrol of<i>Nectria galligena</i>infection of pruning wounds on apple shoots

Abstract

SummaryThe antagonism of micro-organisms towards Nectria galligena in vitro showed poor correlation with their field performance as wound protectants. Inoculating pruning cuts with micro-organisms prior to infection by N. galligena gave protection equivalent to that obtained with benomyl, but with marked reductions in lesion length and spore output.
