Is there a round up that kills weeds but not grass?
Roundup For Lawns₄ is ready-to-use on Southern grasses and kills weeds to the root without harming lawns (when used as directed). This product kills 93 types of weeds, including dollarweed, dandelion, clover, yellow nutsedge, poison ivy, chickweed, oxalis, and purslane (see inside booklet for weed list). Glyphosate is the active ingredient in Roundup, the most commonly used herbicide in agriculture. Several studies have linked glyphosate to an increased risk of cancer. It has been banned or restricted in some American cities and foreign countries because of human health and environmental concerns.
