Japanese Beetles in Corn and Soybean
Kelley Tilmon, Andy Michel
We have been hearing reports of Japanese beetles in corn and soybean.? These beetles are large with a shiny copper and green color.? Foliage feeding in corn is almost never economic, though economic damage from silk clipping is possible (though rare).? Consider a rescue treatment when? silks are https://agcrops.osu.edu/newsletter/corn-newsletter/2018-24/japanese-beetles-corn-and-soybean
Night Temperatures Impact Corn Yield
Alexander Lindsey, Peter Thomison
Low night temperatures during the grain fill period (which typically occurs in July and August) have been associated with some of our highest corn yields in Ohio. The cool night temperatures may have lengthened the grain fill period and reduced respiration losses during grain fill.https://agcrops.osu.edu/newsletter/corn-newsletter/2018-24/night-temperatures-impact-corn-yield
Estimating Corn Yields at Early Stages of Kernel Development
Peter Thomison
Corn growers often want to estimate grain yields prior to harvest in order to help with marketing and harvest plans. https://agcrops.osu.edu/newsletter/corn-newsletter/2018-24/estimating-corn-yields-early-stages-kernel-development
Estimating Soybean Yield
Laura Lindsey
To estimate soybean yield, four yield components need to be considered: plants per acre, pods per plant, seeds per pod, and seeds per pound (seed size).? A printable worksheet to estimate soybean yield can be found by https://agcrops.osu.edu/newsletter/corn-newsletter/2018-24/estimating-soybean-yield

Late Summer Establishment of Perennial Forages
Rory Lewandowski, CCA, Mark Sulc
Ohio growers experienced another wet spring and compressed 2018 spring planting season.? On some farms, this caused postponement of plans for spring seeding of alfalfa and other perennial forages.? In some areas, the prolonged wet weather affected forage harvest schedules, resulting in harvest eq https://agcrops.osu.edu/newsletter/corn-newsletter/2018-24/late-summer-establishment-perennial-forages

Western bean cutworm (WBC) adult moth catches are beginning to decrease for the majority of Ohio counties with an exception in Northeast Ohio. For week ending July 28, 18 counties monitored 63 traps (Figure 1). Overall, there was an average of 15 moths per trap (945 total captured).https://agcrops.osu.edu/newsletter/corn-newsletter/2018-24/western-bean-cutworm-adult-moth-catches-continue-increase
Variable Rate Seeding Focus Group
Laura Lindsey
Ohio State University is partnering with Michigan State University to hold three Variable Rate Seeding Focus Groups during the month of August. We are interested in learning more about how YOU make seeding rate decisions to fine-turn our research and extension outreach.https://agcrops.osu.edu/newsletter/corn-newsletter/2018-24/variable-rate-seeding-focus-group
