I have spiny rush growing in wet parts of hay field. Will crossbow work on them, and will it work on any rush type plant?
Crossbow Herbicide should not be used in areas that stay wet, and it will not be effective for grassy plants or sedges. We would recommend contacting your local cooperative extension for assistance identify the specific plant that you are targeting for the best recommendation. One option would be to use an aquatic glyphosate product (non-selective) to spot treat the area, such as Roundup Custom Aquatic. You will need to use a non-ionic surfactant with this product such as this one.
