As the calendar inches ever closer to June, host of Wheat Pete’s Word and resident agronomist, Peter Johnson, is tackling your top agronomy questions for side-dressing N, fusarium nozzle selection, and early season weed control in this week’s edition.
From two strategies for planting edible beans into dry ground, to the first of the hay crop starting to move off, and on to getting serious about correcting a magnesium deficiency, you won’t want to miss this podcast available here (or download for later!).

- Did you reward the market rally? Sure, it’s not agronomy, but it’s hard to say @WheatPete wasn’t right about this last week…
- Two options for edible beans: plant ’em deep into moisture (even three-inches down), or watch the forecast to avoid potential crusting issues with a rain soon-after planting
- For those looking to conserve moisture, work the ground at night and, while most don’t like rolling bean ground, it may help conserve more moisture
- Speaking of working ground, for those who had big corn crops last year and used European style, high-speed discs, you might be dealing with a bit of a mess. Is a plow the only answer? Noooooo, says Johnson, but we might have to get into strip till situations. No easy answers.
- It’s impressive how quickly the hay crop can be cut and disappear! For those with first cut still out, get out there and keep an eye out for alfalfa weevil
- This hot weather has wheat and corn blasting through growth and leaf stages. Don’t get caught behind! We’re seeing a new leaf every four days. Which leads us to, how much N does corn need? We’re waiting on nitrate results, as estimating mineralization is always so tough. Warm weather helps, but April was cold. Rainfall next month will be a huge driver.
- Hearing reports of manganese deficiency in wheat. Happens more often in high pH, muck soils, so watch for it. If you see it, correct it! Needs 8 lb of manganese sulphate with a spreader sticker, not .1% manganese, like some products have. Be precise; don’t use a shotgun approach for a deficiency
- Which are the best nozzles for fusarium product application? The things to remember are: nozzle angle, coarse droplets, and watch the wind speed. Cut your pressure back if you’re ending up with medium droplets (coarse are less impacted by wind). With fine droplets, the wind controls the spray direction, not you.
- Lastly, Peter Johnson answers questions on: powdery mildew, spots on the leaf bend, white bands on wheat, and twisted flag leaves and snagged heads. On weed control, he talks Xtend antagonism with Group 1s, giant hog weed cautions, sow thistle tips updated form last week, and your options for Roundup Ready beans on Roundup Ready canola stubble.
