Tour 1: On-Site Demonstration of New Technology/Herbicides for Weed Control in Soybean

  1. Comparison of Herbicide Programs for Weed Control in Soybean: Unbiased comparison of several herbicide programs of different companies for weed control in Roundup Ready 2 Xtend and Liberty Link soybeans. New herbicides and multiple herbicide-resistant soybean cultivars will be discussed.
  2. What NOT to do? Considering several herbicide-resistant soybean traits, it is important to know which cultivar you have planted and spray herbicide accordingly. Demonstration plots will be shown to determine if you apply wrong herbicide.
  3. Soybean yield and critical time for weed removal as influenced by soil applied herbicide: Soybean must be kept weed free early in the season in order to avoid yield loss due to weed competition. Weeds will be removed at certain soybean growth stages and soybean yield will be determined.
  4. Weed control and crop safety in MGI soybean: Understand multiple herbicide-resistant soybean and herbicide programs for weed control and crop safety.

Tour 2: On-Site Demonstration of Herbicides for Weed Control in Corn

  1. Comparison of Herbicide Programs for Weed Control in Corn: Unbiased comparison of several herbicide programs by different companies for weed control in glyphosate plus glufosinate-resistant corn. Several new herbicides in corn will be discussed.
  2. Response of white and yellow popcorn hybrids to glyphosate, Enlist DUO, or XtendiMax (26): Nebraska is number one producer of popcorn in the USA. With commercialization of Xtend soybean and Enlist corn, off target movement of dicamba, glyphosate, 2,4-D may injure popcorn. Response of white and yellow popcorn to these herbicides will be demonstrated.
  3. Control of Roundup Ready/LibertyLink volunteer corn in Enlist Corn: Volunteer corn is an important weed in corn-soybean cropping systems. Several fields in Nebraska are continuous corn and control of volunteer corn is a challenge. A project will be demonstrated to control volunteer corn in Enlist corn.
  4. Weed control and crop response in INZEN Sorghum: INZEN sorghum is resistant to ALS inhibiting herbicide–nicosulfuron (Zest). Herbicide programs will be discussed for weed control in INZEN sorghum.

Tour 3: On-Site Demonstration of Cover Crops

1 – 1:15 p.m. – Travel from the shop to Location 1
1:15 – 2:00 p.m. – Location 1 – This session will provide an overview on the effects of cover crops on weed suppression, pests (particularly wheat stem maggot) and beneficial insects.
2:00 – 2:15 p.m. – Travel from Location 1 to Location 2.
2:15 – 3:00 p.m. Location 2 – This session will be on cover crop effects on soil health, including changes in soil microbial communities and soil physical properties with a focus on cover crop root biomass.
3:00 p.m. – Transport back to the shop.
