Does sulfur kill sticker weeds

No, sulfur does not control sticker weeds. The cool-season, free-branching, low-growing annual in question (Soliva pterosperma) is controllable by pre-emergent herbicides applied in fall and post-emergent weed killers dispensed during growing seasons. It may be both controllable and preventable by fertilizer applications when grasses actively are growing and mowing removes no more than one-third of blade heights at a time.
