Weed Control
Management Practices for Weeds on Your Blueberry Operation
The most important method of weed control is preventing current weeds in your field from developing seeds. Some common weed species in blueberry can produce more than 100,000 seeds per plant and can survive in the soil profile for 5 to 15 years. Preemergence herbicides can provide residual weed control for many weeks or months. But the frequent summer rainfall events may move the preemergence herbicide below the area of greatest control. So blueberry growers will rely on postemergence herbicides when they experience a reduction in weed control from preemergence herbicides.
