Purdue University researchers concluded that mixing herbicides with water that's moderate to warm in temperature was more effective on weeds than cold water.

University of Illinois explains how relying on one weed control tool or tactic, or trimming back on weed-control expenditures, can hurt a no-tiller’s bottom line.

With row crop harvest underway, it's time to start planning your fall herbicide applications to control winter annual broadleaf weeds and grasses ahead of grain sorghum or corn.

Now is the time to think about controlling summer annual weeds prior to seed set in cropping situations where this is possible.

Hopefully, most of our full-season soybean crop has been managed for weeds by this time of the summer and some growers have planted or are still considering double-crop. There is still time to ensure your soybean weed control programs worked by scouting those full-season soybeans for escapes and by selecting effective herbicides to control weeds in double-crop soybeans.

As we proceed through the growing season, there are a few issues surrounding weed control and herbicide use. Below are some items to consider.

Early season weed control is imperative to maximize soybean yield. Many soybean growers were unable to apply pre-emergence, residual herbicides prior to soybean emergence.

Nov. 26, 2013 Environmental conditions influence the activity and weed control achieved with any herbicide.

Saturated soils proved to be a challenge for Iowa farmers this past spring. Iowa had 726,350 prevented planting acres according to the Nov. 1, 2013 FSA prevented acres report. More than 619,000 intended corn acres and about 107,000 soybean intended acres were reported as not planted here in Iowa.

This year, due to poor spraying conditions, wet planting conditions and increased resistance, there are a lot of fields with weed escapes.
