For weeds, I use straight vinegar in a spray bottle. However you have to be careful where you spray it, because it's not discriminating. It's effective, it will kill everything, not just weeds.
Make a poison ivy killer spray: Combine 1 cup of salt and 1 gallon of vinegar in a pot and heat to dissolve the salt. Allow it to cool, then add and 8 drops of liquid dish soap and put the mixture in a spray bottle. You can spray the poison ivy or pour it directly on the plant. This will kill all vegetation, so be sure to only apply it to the poison ivy.
2 cups white vinegar
¼ cup salt
Squirt of dawn
Mix in a spray bottle. If you have a larger area, you can mix in a garden sprayer with larger quantities. Use when it will not be raining for a few hours so that it isn’t washed away.
