    Wheat fields will be harvested in Ohio over the next 10 days and many farmers will plant double-crop soybeans. In recent years there has been more interest from livestock producers in applying manure to newly planted soybeans to provide moisture to help get the crop emerged.

    We have heard of and observed increasing potato leaf hopper (PLH) damage in many areas across OH last week. PLH feed similar to aphids, by piercing and sucking on plants causing stunting, thinning and yellowing of alfalfa, often called hopperburn. To scout fields, use a sweep net—a single sweep sample is a set of 10 sweeps, and choose 5-10 different field locations. Treatment is needed if the number of PLH (adults and nymphs) caught a sweep sample is equal to the height of alfalfa. For glandular haired or PLH-resistant alfalfa, the threshold is multiplied by 3.

    It has been an interesting spring. Have questions? We may have the answers; we certainly want to have a discussion. Come to one or all three field days in July. Put these dates on your calendar and plan to attend.

    Author(s): Steve Culman

    This summer a cohort of undergraduate interns are working alongside OSU Extension County Educators to conduct on-farm research. The Agronomic Crop Research Experience (ACRE) interns are placed in county offices throughout the state and work with county educators and state specialists to support on-farm research and extension activities. The program has the goals of 1) training the next-generation of agronomists, 2) empowering locally-directed on-farm research, and 3) identifying solutions to critical agronomic issues in Ohio.
