Corn Newsletter : 2016-12

  1. 16 day total precipitation from May 2
    Author(s): Jim Noel The main headline going forward the next 1-2 week across the corn and soybean belt as a whole is for improving conditions for planting across the region so expect to see increasing planting from west to east in the next 1-2 weeks.
    Mother Nature has decided not to be so nice lately to us. As we talked last week we expected some frost May 15 and 16 and this is exactly what occurred. For the most part temperatures dropped to 31-36F Monday morning but it was mainly a

    Is it still worth putting on a fungicide? If so, what would be the best time to put it on? Via phone, email, or in person, these have been the most frequently asked questions over the last 5 days. The short and simple answer is “it depends”. Some fields have been hit by stripe rust while others have been hit by freezing temperatures, all within the last 7 day. Understandably, most people were planning to hold off on making a fungicide application until

    Over the weekend, temperatures dipped to high 20s/low 30s sometimes accompanied by a frost.  The extent of damage to the wheat crop depends on the growth stage, temperature, and duration of the low temperature.  Wheat is most sensitive to freezing temperatures at the heading and flowering stage.  At

    Last week, we received a few reports from northwest Ohio of twisted wheat flag leaves.  Twisted wheat leaves could be a result of either cold temperatures or 2,4-D herbicide damage.  To determine the cause of the

    Throughout much of Ohio, cool temperatures and saturated soil conditions have delayed corn planting. According to the USDA/NASS (http://www.nass.usda.gov/), during the past week, Ohio corn acreage planted increased slowly (from 30% for the week ending May 8 to 34% for the week ending May 15). The weather forecast this week and beyond promises some relief from rain but many soggy fields will be slow to dry until

    Cold, wet conditions have delayed corn planting throughout Ohio. According to the USDA/NASS (http://www.nass.usda.gov/), for the week ending May 15, corn was 34 percent planted, which was 37 percent behind last year and 20 percent behind the five-year average.

  7. cereal leaf beetle feeding in wheat
    Author(s): Andy Michel, Kelley Tilmon

    With much of the state still yet to plant, growers should be keep a few insect pests in mind as they get in into fields this week:

    Wheat: The two most important insects in wheat right now are armyworms and cereal leaf beetle.  Armyworms are difficult to predict, although the trap data from the University of Kentucky suggests that we may not be in an outbreak year. Nonetheless, it

  8. narrow windrows

    Getting our first cutting of forages this year seems to be shaping up to be another frustrating experience, although we can only hope it won’t be as bad as last year. The outlook for the end of May does not look very promising for a nice stretch of dry weather. While the recent cool weather has slowed development and growth of our forage crops, in central Ohio forage grasses are entering or already well into the heading stage and alfalfa is beginning to show buds. So it is time to

    This week I was asked about applying fungicides to alfalfa because of the wet weather pattern we are experiencing. There are indeed some foliar fungicides that are labelled for alfalfa. The benefit to their use depends greatly on the weather conditions, with positive yield responses occurring when conditions favor foliar diseases. I will share results in a later article. But for now, the important point is that although conditions this spring have favored foliar disease development

  10. Red clover flower
    Author(s): Mark Sulc

    Producing seed of forage species is not common in Ohio, because our climate is not as conducive to high yields of high quality seed of forages as in western and northwestern states. But each year around mid-July to early August I usually get a few questions about how best to produce red clover seed here in Ohio. Although seed produced by reputable seed dealers out west is of higher quality than what we can produce here in Ohio, there are a few management steps that will help

    Data portability is a critical principle for farmers understand in order to capitalize on when using their farm data.  Today, some Ohio farmers are sharing data with up to three trusted advisors and we see the potential to share with 8 or more in the coming years in order to receive information and recommendations.  The main point is that farmers need to have the flexibility to share data

  12. Exact emerge planter
    Author(s): Mary Griffith

    With the ever changing weather pattern, it is critical that farmers take advantage of prime planting opportunities. Planting as efficiently as possible is one key to a successful season. Planters and technology have a come a long way in recent years. From seed singulation and uniform spacing to variable rate seeding and fertilizer application, we are working towards every seed producing its maximum yield. One of the newest planting systems is the John Deere ExactEmerge row
