Only a few late blight severity values have accumulated in some irrigated sites so far this season. The risk of late blight now is low, but continuing cool and wet weather is favorable for late blight. No late blight has been reported in our region.
Preventing first sources of late blight is a critical part of late blight management. These sources of initial inoculum are culls, volunteers and seed. Infected seed can be an early source of late blight inoculum, so it is important to scout fields for late blight early and all season.
