Glyphosate is a broad-spectrum herbicide, which means it kills all kinds of weeds. Glyphosate can be used to kill all common weedy grasses and most broadleaf weeds. It is very effective on poison ivy and poison oak as well as grassy nuisances like crabgrass.

Uses for Glyphosate

Glyphosate is a non-selective herbicide, though, and should be used carefully around plants that you actually want to keep. If you're killing a poison ivy vine that is intertwined with a plant that you want to keep, cut the vines from the base of the plant and carefully pull the vine out from the plant. Then douse the base of the plant that is still in the ground with glyphosate so that the roots will die.

Glyphosate can also be used on grassy weeds like crabgrass. Older turf tends to be less resistant to weed infestation and consequently, weeds can take over. If this occurs, it may be time to kill the whole lawn and reseed the area. Glyphosate, since it's a non-selective herbicide, can help you to kill off an entire lawn so that you can begin planting anew.

Remember to shower well after spraying glyphosate or any herbicide to prevent skin irritation. Be sure to wear long sleeves, long pants, boots and gloves when spraying herbicides and always remember to wash those clothes once you are done spraying. It's probably also a good idea to cover your nose and mouth with some sort of bandanna so that you don't breathe any airborne herbicide.
