Weed Management Field Day Showcases 12 Field Trials

Weed Management Field Day Showcases 12 Field Trials

A University of Nebraska–Lincoln Extension Weed Management Field Day will include on-site demonstration of new technology and herbicides for weed control in corn and soybean.

The event will be from 8:30 a.m. to 1 p.m. Friday, June 27, at the South Central Ag Laboratory near Clay Center. It will include two tours, each with six stops.

Tour 1, 9:00 – 10:15 a.m.

1. Comparison of Herbicide Programs for Weed Control in Soybean: Unbiased comparison of several herbicide programs by different companies for weed control in glyphosate-resistant soybean.

2. Herbicide Program in Dicamba plus Glyphosate-Resistant Soybean: Dicamba plus glyphosate-resistant soybean will be commercialized in the near future. Learn dicamba-based weed control program and crop safety in regulated soybean. Field experiment will provide information for weed control options using several herbicide combinations with dicamba plus glyphosate.

3. Weed Control in Isoxaflutole-Resistant Soybean (Balance GT): Balance™ GT soybean will be tolerant to both glyphosate and isoxaflutole, the active ingredient in new Balance® Bean herbicide. These two chemistries will ensure protection against a variety of weeds, with exceptional performance against both broadleaf weeds and grasses.

4. Trivence Applied Pre-emergence in Soybean: Trivence herbicide gives soybean growers a new weed resistance management tool. Multiple effective modes of action will provide extended residual activity on tough broadleaf weeds in soybean.

5. Control of Common Waterhemp with Soil Residual Herbicides Applied POST in Soybean: Waterhemp emergence is throughout the growing season. Several residual herbicides are labeled that can be applied POST in soybean. Learn how to use residual herbicides such as Dual II Magnum, Intrro, Outlook, Warrant, and Zidua in POST application for waterhemp control.

6. Control of Glyphosate-Resistant Volunteer Corn in Liberty Link Soybean: Learn how to control glyphosate-resistant volunteer corn using Liberty applied alone or with graminicides in Liberty Link soybean.

Tour 2, 10:30 a.m. – noon

1. Weed Control in Popcorn with Herbicide Tank Mixtures: Limited herbicides are available for weed control in popcorn. This project demonstrates weed control with several herbicide tank mixtures in popcorn.

2. Control of Volunteer Glyphosate-Resistant Soybean in Corn: Last year, we received several inquiries about the presence of glyphosate-resistant volunteer soybean in corn fields and cost-effective control options. This stop looks at herbicide options for control of volunteer soybean in corn.

3. Comparison of Herbicide Programs for Weed Control in Corn: Unbiased comparison of several herbicide programs for weed control in glyphosate plus glufosinate-resistant corn.

4. Evaluate Weed Control and Crop Response of Instigate: Instigate is a new herbicide tank mixture of mesotrione (Callisto) and rimsulfuron (Resolve). Learn what will be the best time to apply Instigate for weed control in corn.

5. Anthem/ Anthem ATZ applied Pre-Plant, PRE or POST and in a Sequential Application in Corn: Anthem is a tank mix of Zidua and Cadet for weed control in corn. Weed control efficacy will be compared when Anthem/Anthem ATZ will be applied alone Pre-Plant, PRE, or POST and in a sequential application in corn.

6. Efficacy of Acuron applied PRE for Weed control in Corn: Acuron, a new herbicide contains four active ingredients, including new bicyclopyrone. Weed control efficacy of Acuron will be compared with other herbicides applied PRE in corn.
