Risk for Head Scab – May 30

Pierce Paul

More rain is in the forecast for later this week as wheat fields in the northern half of the state go through the flowering growth stage. Fields flowering today (May 30) are at low risk for scab in the northwestern corner of the state, but the risk will increase progressively later in the week as tropical storm Alberto comes through (see maps for May 30 through June 1 below). Fields in the southern third of the state are now at much less susceptible growth stages for infection by the scab fungus.https://agcrops.osu.edu/newsletter/corn-newsletter/2018-15/risk-head-scab-may-30

Young Corn with Wet Feet: What Can We Expect?

Alexander Lindsey, Peter Thomison, Steve Culman Additional Author: Taylor Dill

Around the state, there are many corn fields with young plants with standing water due to the intense storms that have passed through. But what are the long-term effects of standing water on emerged corn? Preliminary data from two locations in Ohio in 2017 suggests that as long as a sidedress N application can be made following the waterlogging, yield loss may be minimal if the waterlogged conditions lasted 4 days or less.https://agcrops.osu.edu/newsletter/corn-newsletter/2018-15/young-corn-wet-feet-what-can-we-expect

Staging Corn with Severe Leaf Damage Early in the Season Peter Thomison Staging corn development early in the season is usually fairly straightforward. Starting with the first leaf, which has a short rounded leaf tip (sometimes characterized as the ?indicator? leaf), count the number of leaves with visible leaf collars. The collar is the yellow green band that appears at the junction of the leaf blade and leaf sheath. ?But what do you do when leaves are not readily evident due to severe plant defoliation caused by hail (like that shown in the picture above, frost, or a combination of factors?https://agcrops.osu.edu/newsletter/corn-newsletter/2018-15/staging-corn-severe-leaf-damage-early-season

Alfalfa First Cutting NDF Update

Rory Lewandowski, CCA, Mark Sulc, Jeff Stachler, Chris Zoller Lead Author: Angela Arnold

Many hay fields in the region were harvested last week where drying conditions were good. Harvesting will continue into this week if the weather window remains open. The table below reports average neutral detergent fiber (NDF) values from different fields of alfalfa in each county listed. NDF values increased 5 – 6.5 percentage units when compared to last week?s NDF values. Grass fiber would have increased even more, as most hay grass species are fully headed.https://agcrops.osu.edu/newsletter/corn-newsletter/2018-15/alfalfa-first-cutting-ndf-update
