Large crabgrass can form robust root systems thanks to its numerous tillers and capacity to root at stem nodes, allowing it to out-compete crops for moisture and nutrients. Understanding the life cycle and biology of large crabgrass is key to figuring out the best options for its control on your farm. Learn more about non-herbicide life cycle disruptions that can be used in the development of a short and long term management plan through the large crabgrass decision tool fact sheet and an informational video. These resources are one of a five-part weed management series created by Extension Specialist Thierry Besancon and County Agricultural Agent Meredith Melendez, funded by USDA Specialty Crop Block Grant AM190100
