Is Planting Green a Useful Tool for Managing Multiple-Resistant Waterhemp?

January 19, 2023 | Posted in Seeding Practices, Termination

For the past two years, we have been participating in a multi-regional US Soybean Board funded experiment that is investigating the effects of planting green on no-till soybean production and management of multiple-resistant waterhemp populations. Planting green is the delay of cover crop termination until after cash crop planting, which is a departure from the standard practices of terminating a cover crop 10-14 days prior to planting. Our coordinated project focused on no-till soybean (30" row spacing; Enlist system) preceded by cereal rye (60 lb/ac) that was sown after field corn.

[Podcast] Controlling Waterhemp with Cover Crops

This week’s podcast, sponsored by Bio Till Cover Crops, features Meghan Anderson, Field Agronomist with Iowa State University Extension. Anderson will discuss why waterhemp has become so difficult to control in recent years, how growers can identify waterhemp, how cover crops can be leveraged against waterhemp, and more.

Waterhemp control is an increasing challenge for soybean producers due to the evolution of multiple herbicide-resistant populations. With dwindling herbicide resources, there is a need to integrate non-chemical strategies into current weed management programs in soybean.

Farmers who want to plant cover crops after corn and soybeans also want to control resistant weeds like marestail, waterhemp, and giant ragweed. Often the residual soil herbicides remain active and have a long residual or half-life that could hurt cover crop establishment.

An article from Iowa Soybean Assn. discusses Chad Ingels' experience planting soybeans into tall, green cover crops and the potential benefits of this practice on yields and herbicide costs for farmers who pursue the practice.

Cover Crops Offer Bright Future for Weed Control, Further Conservation

Illinois grower Randy Chapman hopes cover crops will help him move from strip-till to 100% no-till while cleaning up herbicide-resistant weeds.

When Randy Chapman started farming with his father, he knew they weren’t going to have the help they needed for labor. He also didn’t like the erosion he witnessed from tillage and realized they had to do something different.
