Here is another good article on the dry weather:residual herbicide interaction. Bottom line is the same. If you planned to use a residual herbicide, then use the residual herbicide.
I have been referring to Dr. Hartzler's @IowaWeeds 2021 article for the question that keeps coming up:
"Preemergence Herbicides, Dry Soils and Rain"

This week on ATA Lance will be joined by @ILWMTechDev, Crop Protection Tech Development Rep. They will review Bayer's Chemistry Pipeline and discussing the key differences between weed management and weed control. We will see you Thursday at 7:30 AM!

Reposting an article about rain and herbicide activation we wrote for the Pest and Crop a few weeks ago. Starting to get questions about this topic and there is very little rain in the forecast. extension.entm.purdue.edu/ne…

Great information and timely reminder from Dr. Sikkema. It's difficult to be too early with your POST corn herbicides, but much easier to be too late.

The US Environmental Protection Agency is beginning to make changes to pesticide labels because of the Endangered Species Act (ESA). Please take time to learn more about the ESA; it will impact future pesticide applications. Dr. Bill Chism is an excellent resource on this topic.

Disease pressure has been fairly low across a good portion of my area, but diseases are starting to show up. It’s a great time to get out and scout. You’ll find some fungi.

For those with irrigation, just a reminder that your fields are an island. With drier conditions and ⬆️ irrigation frequency, it can provide better environments for disease than others. This was found yesterday, low in the canopy of V10 corn of an irrigated field. % still V low.

Crop planted but no PRE applied? Be sure you know if your PRE of choice can be applied after crop emergence or if it must be applied before crop emergence.

In this 2021 Ontario trial GR Canada fleabane control was: dicamba > Elevore > 2,4-D applied preplant to soybean. Upper left - control. Upper right - dicamba. Lower left - Elevore. Lower right - 2,4-D.

Hot off the presses- the Latest EU assessment of glyphosate. Basically consistent with 40 years of independent, international regulatory oversight. Inconsistent with California juries. – at Florida, USA

Same here! PRE treatments (#WiscWeeds weed management in XtendFlex soybean systems study):
✅ nontreated check (plot 207)
✅ Fierce EZ @ 6 fl oz/a (plot 204)
✅ Fierce EZ @ 6 fl oz/a + Xtendimax @ 22 fl oz/a (plot 203)
Representative pictures taken 21 days after treatment.

Not sure who needs to hear this, but you don't have to wait for severe weed pressure or maximum leaf stage to go and apply herbicide.

Dry conditions leading to better than expected residual control of #pigweed #waterhemp (Amaranthus tuberculatus) with #dicamba in our research plots.

While it’s been dry in Iowa, @ChannelSeed hybrids have been hamming down on root development finding water and nutrients. Excited to see how these preform throughout the year for @Iowa_Channel
