Here's a quick refresher on exactly how cold temperatures affect immature corn and soybeans.

Insecticide and fungicide seed treatments rarely pay off for soybean farmers, according to a new meta-study.

After two years of clean fields, weed escapes are catching eyes in some Xtend crop fields.

Will corn and soybean finish before a freeze? And how do farmers stay sane waiting for that verdict?

Like many in agriculture, Justin McMechan hopes 2019 was an outlier -- a freak season that won't be repeated anytime soon.

Don't assume Bt traits will protect your field corn from damage.

Unlike last year, the EPA is not receiving routine updates from states on dicamba problems, even as injury complaints hit record levels in at least one state this summer.

A wet spring and record flooding have kept Kansas and Missouri's 2019 yields near their droughty levels in 2018, according to Gro Intelligence's satellite-driven yield models.

Southern entomologists are monitoring the situation and testing some populations for resistance.

Most farmers could use a little rain and a lot of clarity on the yield potential of the beleaguered 2019 crop.

Dicamba is once again the primary culprit in off-target injury complaints, but some 2,4-D complaints are surfacing as well.

"We will be at a bit more elevated risk in western Kansas this year," she notes. Plentiful rain throughout the summer allowed volunteer wheat to germinate and emerge continuously through the summer months and September, she says.

Is Bt broken for ear-feeding pests? And, if so, can we rescue it?

Say "cocklebur" or "velvetleaf," and Zack Rendel is suddenly 8 years old again, sitting in a John Deere 4020, pulling a six-row cultivator.

Scientists have found populations of European corn borer in Canada that are fully resistant to the Bt trait Cry1F, sold under the brand name Herculex I.

If prevented planting acres left you with unused treated soybean seed, think twice before holding that seed for planting next year.

"It's not a mayday situation," one industry source noted. But supplies might be tighter for certain products.

Southern corn rust, gray leaf spot, Japanese beetles and western corn rootworm beetles top the list of this week's crop pests.

"It's not a mayday situation," one industry source noted. But supplies might be tighter for certain products.

Cornfields are starting to show the consequences of wet and delayed planting conditions.

Soybean gall midge has been reported in Iowa, Nebraska, Minnesota and South Dakota so far. Western bean cutworm is actively laying eggs across the Corn Belt.

Winter wheat fields that lived through delayed planting, flooding and hail benefited from the below-average temperatures and plenty of moisture.

This week's Crop Tech Corner examines two different ways scientists are trying to remove food allergens from two crops -- peanuts and wheat.

Most farmers are done planting and replanting. Now they'll turn to prevented planting acre management and managing crops that got a rough start to life.

If ever there was a crop year to expect the unexpected, it's 2019 -- and pests are no exception.

North Dakota just announced a dicamba extension, as the first injury reports of 2019 surface.

Storage could be less successful given lower quality and germination rates from the late 2018 harvest.

What lies in wait for emerging soybean plants? Aphids, bean leaf beetles and soybean gall midge have been spotted.
