Are you in Iowa and want some traps to monitor corn rootworm beetles this summer? I have some for you - details on how to sign up here: https://t.co/UCmc9qAdO8.

One of these things is not like the others. About time for a POST application in this field! #ISUCrops

[Meaghan Anderson @mjanders1]

@dikesmarshfarm This was for a headed out cover crop with soybeans planted in it. Not much for weeds underneath, so the plan was to come back with an early 2nd POST + residual to control weeds once the rye is dead.

[Meaghan Anderson @mjanders1]

A recent glyphosate-only burndown herbicide application for cereal rye had some contamination that resulted in contact burn to emerged soybean seedlings. Tank/boom/etc. contamination is common as we switch from PRE to POST apps. #ISUCrops

Sometimes, there is nobody to blame but the wildlife. 🐿️🦌 #ISUCrops

[Meaghan Anderson @mjanders1]

Scouting shortly after emergence is an incredibly useful exercise. Sometimes you find surprises, like a pass that was planted without the downforce engaged. #ISUCrops

@Jake8420T @nciacrops This looks like it could be clammy groundcherry, but I’m not certain from the image. It’s a perennial with rhizomes belowground and densely fuzzy leaves. https://t.co/aBs29Wx66K

This will be a big week for corn postemergence herbicide applications to really ramp up. We’ve got morningglory, velvetleaf, and grasses emerging in these management plots at @ISUFieldLab. #ISUCrops

[Meaghan Anderson @mjanders1]

Crop Scout School at @ISUFieldLab is kicking off with a full house this morning! #ISUCrops

Low soybean stands don’t always mean replanting is the best answer. This new ICM Blog breaks down when to leave it, repair it, or replant 👇

@FarminForLife I think we’re something like 1% of average since the beginning of May, so I’d be game for a temporary trade of weather conditions.

[Meaghan Anderson @mjanders1]

Soybean plots in the ground. Soybean seeds are in a little moisture but the rain this weekend will be perfect for them! #ISUCrops

@XtremeAgFarming @AgricenCo I hope Kelly is also testing the -40 units of N without the Agricen to see how that alone compares with the biological product and the higher N rate. 🤞

[ISU Crop News @ISUCropNews]

Soil crusting + sidewall compaction may look different—but both limit emergence, root growth, and early vigor. With reports of both coming in from the field, take time to check your fields!

We've had reports of cutworms activity. While we focus a lot on black cutworms (migratory) in corn, they are't the only species! There are also bronzed and dingy cutworms (native).

April 23 planting sidewall now like concrete. #ISUCrops

[Meaghan Anderson @mjanders1]

@LauraToben @NicoleStecklein @1boilerfan Will certainly survive, though I think that stem kink will remain for the duration.

[Meaghan Anderson @mjanders1]

@alex_woodall @nciacrops This was on a pretty light soil, which played a big role in how few plants were affected. I’m sure it could’ve been much worse with heavier rain or heavier soil!

[Meaghan Anderson @mjanders1]

Soil crusting wasn’t as big a problem in this field but it did have about 2% of the population leafing out underground or emerging late. This was planted April 22. #ISUCrops
