Post-Harvest Weed Control in Winter Wheat
June 29, 2016
Timely control of weeds following winter wheat harvest can limit soil moisture loss to weeds and prevent the deposit of more weed seeds in the soil, two factors that can benefit the next crop's yield. In addition, timely control of volunteer wheat is essential in reducing the spread of wheat streak mosaic disease. See what influences effectiveness of weed control and how to make your crop more competitive.
Control Volunteer Winter Wheat and Other Weeds Now to Increase and Protect 2017 Yields, Income
June 23, 2016
By far, the greatest risk of losses from mite-vectored viruses occurs when there is a summer "green bridge" of volunteer wheat emerging before harvest. This almost always occurs as a result of wheat seed head shatter from hail storms (Figure 1).
Herbicide Injury and Pathogen Infection on Soybean Seedlings
June 17, 2016
In an ongoing survey for soilborne pathogens in soybeans, closer examination of soybean seedling injury in a Keith County field found several causes, including herbicide injury and damping off from Fusarium or Rhizoctonia root rot.
Controlling Summer Grasses In Alfalfa
June 10, 2016
Wet soils in alfalfa fields right after cutting can lead to quick growth of weedy grasses like foxtail and crabgrass, particularly in a thin alfalfa stand. Ensuring a thick stand with good fertility and select herbicides can help you keep grasses under control.
Weed Management Field Day June 29 at Clay Center
May 26, 2016
Growers, crop consultants and educators are encouraged to attend Nebraska Extension's Weed Management Field Day from 8 a.m. to 1 p.m. June 29 at the South Central Agricultural Laboratory near Clay Center.
Acuron™: A New Corn Herbicide
May 19, 2016
As growers look for new opportunities to rotate herbicide active ingredients, combination herbicides may offer the benefits they're looking for. Acuron™ is a combination of four herbicide active ingredients: atrazine (10.93%), bicyclopyrone (0.65%), mesotrione (2.6%), and S-metolachlor (23.4%) plus the safener benoxacor. Acruron may be used pre-emergence and post-emergence in field corn, seed corn, and silage corn. Acuron may also be used in sweet corn and yellow popcorn, but the application must be made prior to crop emergence or serious crop injury may occur.
New Chart Aids Selection of Diverse Site of Action Herbicides
May 10, 2016
A new herbicide selection chart can help growers select products with diverse modes and sites of action which, in turn, will help reduce the development of herbicide-resistant weeds.
