Although the corn trial areas had adequate moisture for eatablishment, the soybean trial areas ended up being too dry to get a good stand of covers without drilling into moisture

Decent stand of covers coming in after research trials are taken out. Still having good activity with my alley mix 👍.

Luckily my trial locations survived the high winds. That being said, could have done without the hail damage from this weekends storms. Hail damage will be an additional stressor added as well as an easier infection point for disease.

Fun fact. This is actually raccoon damage…😉

My bottle cap pile has been somewhat diminished over the years. Fellow weed science folk know my struggle 😂.

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" 🔗 crops.extension.iastate.edu/…

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…

Soil Applied Herbicides and Rainfall for Activation

Fieldwork has progressed slowly in the past week due to cool air and soil temperatures.

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.

From 2018-2021, the average price of corn was $5.94 in Ontario (OMAFRA). If weeds are up to 2, 4, 6, and 8 inches in height at time of postemergence herbicide application the loss in $/acre was $30, 104, 181, and 241, respectively. Corn is very sensitive to weed interference.

Although initial antagonism was apparent with some of these combinations, termination has mostly occurred but time to kill was greatly increased. Same plots 23 days later

Impact of various tankmixes with Powermax 3 on cereal rye burndown 10 dat. Pretty good example of antagonism in any burndown plots with metribuzin included.
