Road trip Effingham

I made a short road trip to Effingham today to do a septic tank evaluation.  Most of the corn along the way was pollinating or past pollination, although not in some of the uneven parts of fields.  Some fields are starting to run out of nitrogen.

Soybeans looked better than corn.  We had a lot of rain earlier in the week and the soybeans were putting on a lot of top growth.  Two issues that will cut into yields at this point are weeds that were starting to show through, and poor stands.

Zombie Weed Apocalypse

The growing season of 2019 just keeps on giving. Without going over all the morbid details, let’s just say that it’s been challenging from the very beginning, and looks like the challenges will continue on through to harvest and beyond.

As we get into the latter part of summer we are still contending with weeds that have refused to die. For lack of a better term, zombie weeds. These weeds have had burndown herbicide treatments, pre-emergent residual treatments, one or more post treatments, and still refuse to die. Some are newly emerged, some have just not succumbed to the programs we had planned before the spring weather went off the tracks. And now they have gone to seed, or soon will.

At this point, another spray trip becomes little more than an attempt at revenge. The plants are way above label size restrictions, and have hardened off with the dry conditions of the last few weeks. The chances are they won’t die, and the seed on them is probably already viable to bring on the next generation.

Am I going to give you the solution to the zombie weed apocalypse? Probably not. But I’ll point out that this weed control disaster isn’t a failure in any one program or system. We can find fields under all types of management that is experiencing problems, owing mainly to the conditions of the growing season. What I will say is this: start right now addressing the weed problems that will probably be coming our way in 2020.

Since many, though not all, weed control systems now combine seed traits with herbicide products, now is the time to start putting those combinations together. These systems must start with variety and hybrid selection, and seed companies will be on your doorstep early this fall. Choose a system that fits your needs from a production standpoint as well as weed control ability.

Consider cover crops to suppress weeds this fall. Some cover crop mixtures are better than others at keeping weeds down, and the consideration on how to terminate these crops needs to be factored in. Seed supplies may be an issue, as well.

Talk to your retailer about a fall burndown treatment. This can make a tremendous difference in weed pressure in the spring. With what looks like an extended harvest, it is crucial that you make your plans and let your retailer know with plenty of time what you intend to do.

So as you look out over your fields, frustrated with the zombie weeds poking through your crops or covering your Prevented Planting acres, remember that they aren’t coming after your brains, but you will need to put your brain to work now to prepare to hold them in check in the coming seasons.
