One of the first steps to a successful herbicide program is starting clean to allow the pre-emerge herbicide to reach the soil surface. The burndown also allows the opportunity to utilize other “effective” sites of action (SOA) that can’t be used in-season such as Gramoxone® SL 2.0. Spraying early in the spring provides the opportunity to control winter annuals like marestail and emerging summer annuals such as giant ragweed. When evaluating spring burndown options, we must consider if the herbicide has burndown only activity or burndown plus residual activity. Products like Liberty® and Gramoxone SL 2.0 will not have any residual activity but will provide very effective burndown activity. Other burndown products such as Sharpen® or metribuzin will provide residual value depending on the herbicide rate.

The fall of 2018 brought many challenges to the region, making it difficult for fall anhydrous applications or a fall burndown. The February issue of CropTalk had the first part of this series. We hope to give you insight on options for spring management if you did not finish your traditional fall fieldwork. The first article, available on the Beck's website, focused on considerations for applying spring anhydrous. This article will focus on how to maximize the efficacy of a spring burndown.
