63-2022 Determining Duration of Residual Control of Soil-applied Herbicides to Form Total Preemergence Herbicide Programs in Soybean annual report

To overcome herbicide resistance and protect remaining chemistries from resulting in developed herbicide resistance, it is crucial to utilize as many herbicide chemistries as possible to manage weed populations. These proposed studies would investigate a wide spectrum of soil-applied herbicides for their ability to alleviate selection pressure on POST chemistries. Not only do soil-applied herbicides have the potential to slow the development of herbicide resistance, but programs built upon these chemistries could result in an entire cropping season without competition from weedy species.
