    An active weather pattern will remain across the corn and soybean belt for the rest of May into the first week of June. A large high pressure will strengthen across the Southeast U.S. with hot and dry weather. At the same time, very cool air for this time of the year will be in place in Canada. This will result in an active front going back and forth in the north and central U.S.

    In northern Ohio, most of the wheat fields are between Feekes growth stages 9 (full flag leaf emergence) and 10 (boot), with the odd early-planted field or field planted with an early- maturing variety beginning to head-out. In southern Ohio, fields are between Feekes 10 and early flowering (Feekes 10.5.1).

    What should I spray for scab and vomitoxin control? With the addition of Miravis Ace (a new DMI + SDHI premix) to the list of fungicides recommended for the control of Fusarium head blight (head scab) and vomitoxin in wheat and barley, questions are being asked as to whether it is any better than Prosaro and Caramba. In 2018, we compared the three fungicides on scab susceptible varieties across 12 environments and found that in terms of efficacy against head scab and vomitoxin, Prosaro, Caramba, and Miravis Ace were very comparable.

    Many alfalfa and forage stands across the state took a beating this winter and the wet spring has added insult to injury. For weak stands, harvesting a little later than normal will help them recover. However, we’ve seen some younger stands that are looking OK and are overall growing well despite the wet weather.

    Orchardgrass was beginning to head out last week in Clark county and the alfalfa is ready or about ready for cutting (see below) in central Ohio and points to the south. Unfortunately, the rainy weather is hampering any attempts to harvest.

    The Wayne County Extension IPM scouting program has been monitoring ten alfalfa and alfalfa/grass mix fields for alfalfa weevil larvae since the beginning of May.  Although weevil larvae numbers have increased somewhat over the past couple of weeks, numbers are well below threshold treatment levels and this appears to be consistent across the state this year.  Our scouting and sampling have resulted in averages ranging from 0.33 to 0.50 larvae per stem when sampling 5 to 6 random areas for every 25 acres.  Alfalfa height on our last sample date of May 14 averaged from 15 to 25 inches across

    Cool, wet conditions have been the perfect weather to favor slug populations.  Slugs are able to eat many types of plants, and even in fields that haven’t been sown yet slugs can successfully feed on weeds.  Late planting in many areas may cause more slug headaches than usual this year – as slugs get geared up, the small size of both soybean and corn will lead to a greater damage potential from them.

    Many forage stands were damaged this past winter, and the wet spring has further deteriorated stands that appeared they might recover. It is now too risky to try to establish perennial forages, with the warmer summer weather at our doorstep. We should wait until August to establish perennial stands. Meanwhile, what options can we consider for growing forage this year?

    We are also well past the time when cool-season species like oats, triticale, Italian ryegrass, spring barley can be planted. As we move into late May and early June, we must switch to planting warm-season species.

    We are past the middle of May and I’m getting calls for data already on the seed treatment trials that we have scheduled for the 2019 season.  But in all honesty, I’m glad they weren’t in the ground!

    Production costs for Ohio field crops are forecast to be largely unchanged from last year with slightly higher fertilizer and interest expenses that may increase total costs for some growers. Variable costs for corn in Ohio for 2019 are projected to range from $356 to $451 per acre depending on land productivity. Variable costs for 2019 Ohio soybeans are projected to range from $210 to $230 per acre. Wheat variable expenses for 2019 are projected to range from $178 to $219 per acre.
