Dry bean planting is progressing rapidly with many of the first planted fields from late last week emerging.
In potatoes, nearly every producer is now finished planting and replanting. Hilling and cultivation is in progress. Colorado potato beetle adults are active and egg masses and larvae are easily observed on untreated potatoes.
