Preplant Tillage to Manage Glyphosate-resistant Common Ragweed February 13, 2018

Nebraska university weed scientists conducted research in 2017 to identify the effect of preplant tillage on weed emergence in an effort to develop an integrated weed management plan to control glyphosate-resistant weeds. Here's what they found.

Does Weed Control Method Impact Indiangrass Establishment and Persistence? February 5, 2018

This study evaluated two weed control methods and seeding rates on establishment and persistence of two indiangrass cultivars, ‘Oto’ and ‘NE 54’, from 2003 to 2007.

Herbicide label section — Figure 1. A careful read of the herbicide label provides important legal and educational information for your weed management program. An example of a group 2 herbicide from the sulfonylurea family and a list of other herbicides that belong to the same group and family. Paying attention to the group name makes it easier to ensure that herbicide(s) from the same group are not repeated within a growing season or the next year.

What Should You Look For in a Herbicide Label January 26, 2018

A herbicide label is a legal document providing important information about a herbicide, its appropriate use, and the precautions needed to avoid off-target movement and to protect environmental quality. It can also help you achieve the most efficient and sustainable application. Learn more about what to watch for on herbicide product labels.

Results of 2017 Survey on Nebraska Soybean Farmers’ Adoption of Xtend Technology and Off-Target Dicamba Movement December 14, 2017

In summer 2017, 312 Nebraska farmers from 60 counties responded to a survey on their perception on dicamba use in Xtend soybeans. The survey asked about outcomes of applying dicamba in Xtend soybeans and perceived injury in non-Xtend soybeans.

Low Temperature and Frost May Affect Efficacy of Burndown Herbicides November 9, 2017

In many areas fall herbicide applications were delayed due to the late harvest. Applications can still be effective, depending on weeds present, temperature, rate of herbicide and additives used. The article offers recommendations for these late-fall applications and their importance, particularly for control of herbicide-resistant marestail.
