Non-GMO Soybean Weed Management Fact Sheet

Nov 25, 2020

By Mark Loux

An updated version of the fact sheet “Herbicide Programs for non-GMO soybeans” is now available. A print ready version can be found here, and it’s also available on Ohioline here. The basic approach with herbicides has not changed much. Weed control in non-GMO soybeans can be challenging, and increases the selection for resistance to site 14 herbicides (fomesafen, Cobra). The new version emphasizes several things, including:

- Plant non-GMO soybeans in fields with a history of several years of crop rotation and effective weed control that has prevented weed seed return to the soil and reduced weed populations.

- Maintain a rotation where non-GMO soybeans are planted every four years, with two years of corn and one year of traited soybeans in between, or other crops as appropriate for the farm operation.

- Fall herbicide treatments should be used to manage marestail, winter annuals, dandelion, and other perennial weeds. Marestail can be especially difficult to control in no-till, non-GMO soybeans unless a fall herbicide treatment is used.

- Planting non-GMO soybeans in fields with waterhemp is not recommended due to the high frequency of resistance to ALS and PPO inhibitors, which eliminates all POST options for control.

Video: Canada reaches tariff deal with China on canola, electric vehicles

Canada has reached a deal with China to increase the limit of imports of Chinese electric vehicles (EVs) in exchange for Beijing dropping tariffs on agricultural products, such as canola, Prime Minister Mark Carney said on Friday.

The tariffs on canola are dropping to 15 per cent starting on March 1. In exchange for dropping duties on agricultural products, Carney is allowing 49,000 Chinese EVs to be exported to Canada.

Carney described it as a “preliminary but landmark” agreement to remove trade barriers and reduce tariffs, part of a broader strategic partnership with China.
