What herbicide kills liverwort?

Answered by Jason Smith

Liverwort is a common weed that can be troublesome in gardens and landscapes. One effective way to control liverwort is by using preemergence herbicides. These herbicides are applied before the weed seeds germinate, preventing their growth and establishment.

One herbicide that is labeled for liverwort control is flumioxazin. It is available under different brand names such as SureGuard and Broadstar. Flumioxazin is a water dispersible granule formulation that can be easily mixed with water and applied to the soil surface.

When using flumioxazin for liverwort control, it is important to apply it as a directed application to the container substrate surface, while avoiding contact with ornamental crop foliage. This helps to minimize any potential damage to desirable plants while targeting the liverwort.

In my personal experience, I have found flumioxazin to be quite effective in controlling liverwort. I have used it in both garden beds and container gardens, and it has provided satisfactory results. However, it is important to follow the label instructions carefully, including application rates and timing, to ensure safe and effective use.

Here are some key points to keep in mind when using flumioxazin for liverwort control:

1. Read and follow the label instructions: The label provides important information on application rates, timing, and safety precautions. It is essential to carefully read and understand the instructions before using the herbicide.

2. Apply as a directed application: To avoid damage to ornamental crop foliage, it is crucial to apply flumioxazin directly to the container substrate surface. This helps to target the liverwort while minimizing contact with desirable plants.

3. Use the recommended rates: The label will specify the appropriate application rates for liverwort control. It is important to use the recommended rates to ensure effective weed control without causing harm to desirable plants.

4. Timing is key: Flumioxazin is a preemergence herbicide, so it should be applied before liverwort seeds germinate. Timing will depend on the specific weed species and local conditions. It is best to consult the label or seek advice from a local horticulture expert for guidance on the ideal timing for application.

5. Monitor and follow-up: While flumioxazin can provide effective control of liverwort, it is important to monitor the area for any regrowth or new weed seedlings. If necessary, follow-up treatments may be required to maintain control.

Flumioxazin is a preemergence herbicide that can be used for liverwort control. When used correctly and according to the label instructions, it can provide effective control of this common weed. However, as with any herbicide, it is important to exercise caution, follow safety guidelines, and consider the specific needs of your garden or landscape.
