As we expected, SWD pressure is hitting early. SWD larvae have been found in salmonberries, elderberries and other wild fruit and Michael Dossett has seen larvae in his early fruiting seedling block at the Clearbrook substation. While raspberry machine harvest could be starting soon, most fields are now starting to ripen fruit, particularly on weak laterals and loops. We learned in 2013 that this fruit must be protected or it will act as an SWD magnet and carry into an infested first pick. A Malathion spray is recommended now to protect this early fruit followed by a Capture application just before harvest.

Note: If there is still bloom in the field, sprays should be applied at night to protect the bees.

for detailed recommendations.
