Field Observations – Week of May 23

Weekly Field Update – Jefferson & Harrison Counties

This week’s field tour across Jefferson and Harrison Counties revealed a dynamic landscape of plant development and pest activity as we head into late May.

Blooming Species:
Several invasive and native species are currently in bloom, including dame’s rocket, multiflora rose, bush honeysuckle, wild parsnip, cow parsnip, and poison hemlock. These blooms are not only visually striking but also serve as indicators for land management and weed control timing.

Weed Presence:
Hemp dogbane and nightshade were observed in multiple fields, signaling the need for early-season weed management strategies.

Crop Development:

• Soybeans in south-central Jefferson County are progressing well, with most fields in the V1 to V2 growth stages.

• Corn in the same region is largely in the V2 stage.

• Hay fields are in various stages, with some already undergoing first cutting. Many fields are in bloom or have developed seed heads, particularly in south-central Jefferson and Harrison Counties.

Soil Conditions:
Soil moisture levels down to 6 inches remain adequate, supporting healthy crop development.

Pest Alerts:

• Spotted lanternfly nymphs were seen in Mingo Junction. Early detection is key to managing this invasive pest.

• Hemlock woolly adelgid was identified in southern Jefferson County, posing a threat to native hemlock populations.

Landowners and producers are encouraged to monitor their fields closely and report any unusual pest activity to the county extension office.
