Updated spore counts from our spore trap sites are now available below.

In general, spore production has tapered off at most sites, though a considerable number of spores are still being captured at KBG-1 (central Oregon) and KBG-4 (upper Columbia Basin).

Spore production should decrease as daily temperatures begin to regularly exceed 80°F.

Field scouting for honeydew at this time can help identify infected fields which may present difficulties during harvest and seed cleaning operations.

Prioritize monitoring efforts in fields that were infected last year, as well as fields in close proximity to previously infected fields.
