Wheat Weed Control

The recent rains should give the 2007 wheat crop a running start. However, fall moisture brings the possibility of winter annuals that can compete with your crop for nutrients and moisture.

Broadleaf weeds such as mustards often emerge in the fall and winter, but rarely require treatment until the spring. All the SU (sulfonylurea) products do a good job of controlling these weeds; we can help you pick the right one for your crop rotation.

If you need a topdress fertilizer application in the spring, all these herbicides can be tank mixed with our popular High-NRG N®.

Grass weeds like jointed goatgrass and downy brome (cheat grass) are harder to control: they can emerge in either the fall or spring, and the timing of herbicide applications becomes more critical. The product of choice for jointed goatgrass and downy brome control is BASF's Beyond®, but it can only used on Clearfield® wheat. Clearfield® is a non-GMO cultivar with several wheat varieties available.

Beyond™ should be applied to small, actively growing weeds, when they have 3-4 leaves. To get residual control for later flushes, rainfall or irrigation is required after application.

If you don’t have Clearfield® wheat, Olympus® (or Olympus Flex®) from Bayer has shown promising results on downy brome, although it only has a suppression label on jointed goatgrass. The best timing is when most of the first flush of downy brome has emerged and is actively growing, but is no larger than 2-3 tillers. This will likely be mid-October and mid-November. For control of later flushes, about 1/2" of rainfall or irrigation is required after application.

It is important to remember that these products can do a good job of reducing heavy grass pressure if conditions are good, but they will almost certainly not give 100% control.

Corn Insect Review

The biggest news in 2006 was the dramatic price decrease in Capture® and products with the same active ingredient, bifenthrin. This mid-season price reduction change made spider mite, ECB and rootworm beetle control much more economical, and the short 12 hour re-entry period (REI) was also a benefit.

The negative news is that Furadan® (used for rootworm control) is under an EPA re-registration review, called IRED, and some uses may be discontinued--we'll keep you posted.

Fall Pasture Treatments

Fall is the best time to spray for musk thistle. We will be using Milestone® this year. If there are trees nearby, we like to wait until the leaves have fallen to avoid damage. Please bring us maps with the critical areas marked, and we'll treat where you have indicated.

Milestone™ is new chemistry: click here for a popup with more information.
