Time to buy a couple of gallons of Round Up for future use...if anything does a good job, time to have a report that says its bad for you, remove it from the market...
buy straight Glyphosate.
Round-up in the little squirt bottles is only about .5%. you pay about $7 bucks for a quart of water and a spritz of Glyphosate.
Can buy 2 1/2 gallons of 41% for 30 bucks at the farm store.
one jug will last the rest of my life
