Palmer Amaranth Control in Dry Bean January 14, 2019
Residual herbicides applied at or before planting are critically important to controlling emerged Palmer amaranth in dry bean. Research at the Panhandle REC assessed the efficacy of PRE and pre-plant incorporated (PPI) residual herbicide programs.
The Importance of Early Season Weed Control January 9, 2019
Do early season weeds have the same impact as later season flushes? Researchers here report on a 2018 study conducted in dry bean to compare how soon after planting crop yield was impacted by weed presence.
Fall Strategies for Weed Control in Winter Wheat August 29, 2018
Managing weeds at least two weeks prior to planting winter wheat and then controlling winter annuals this fall are important to reducing disease, saving soil moisture, and achieving top yields next summer.
What Would Happen if We Stopped Controlling Weeds? July 19, 2018
A recent study of 10 years of research in key dry bean production areas of the US and Canada showed the value of weed management. Without weed control losses were estimated at $720 million.
Coal Combustion Residue: A Potential Soil Amendment February 22, 2018
University of Nebraska researchers applied char, a by-product of sugar beet processing, at three sites to study its effect on soil properties.
Herbicide-Resistant Kochia, Palmer, and Waterhemp in the Panhandle: Distribution and Management January 8, 2018
Several field trials were undertaken in 2017 to look at options for controlling herbicide-resistant kochia, Palmer amaranth, and waterhemp in dry bean, corn, and sugarbeet. In addition over 80 kochia, Palmer amaranth, and waterhemp plants were collected for testing of herbicide resistance. Of these 50% of kochia and 13% of Palmer amaranth plants tested were resistant to field rates of glyphosate. While options are limited in the Panhandle, pairing crop rotations with herbicide programs using PRE and layby treatments provided effective control of key weed species.

When To Replant Sugarbeets: The Relationship Between Population, Yield, And Replant Timing January 8, 2018
An article from the Proceedings of the 2018 Nebraska Extension Crop Production Clinics: Early season stand loss from wind or frost can be severe enough to require replanting of a sugarbeet crop. Three years of field trials at the Panhandle Research and Extension Center were conducted to determine just how much stands need to be reduced to justify replanting.
Take Advantage of Warm Weather this Winter to Control Downy Brome February 20, 2017
Just a month after double-digit below zero temperatures, Nebraska hit an extended period of above normal temperatures, coaxing weed seeds to germinate early in many fields and pastures and creating the need to tackle the influx early.
