Bests & Worsts Reviews from Amazon

If used carefully (a full-bodysuit, chemical mask, shoe covers and gloves) this is the best Roundup to use. It kills weeds, but also many kinds of bushes too. It kills 15’ high cane weed in Hawaii, it kills scrub brush in AZ. Use it carefully, read the entire label. I’ve seen folks spraying weeds in shorts and flip-flops many, many times. Don’t be stupid, this is powerful stuff. Protect yourself. The disposable plastic full-body white suits from Home Depot made for crawling under your house will protect you fairly well. Chemical gloves are a must, as is a chemical/vapor-type mask. I also use disposable shoe covers and spray very carefully. Check wind direction carefully. Winds can change and swirl. Always spray downwind, and as close to the ground as possible. Roundup only works on leaves. Spraying the ground does nothing. You don’t need to blast it all over, only on healthy leaves. It’s absorbed into the plant in 30 minutes, so rain after that is OK. I’d also buy the inexpensive wetting agent that helps it stick to leaves, and the blue dye, that shows you where you’ve sprayed — so you don’t waste any by spraying an area twice. I’ve been told food coloring works too. The blue fades in a day or so. When used AS DIRECTED, this is excellent weed/brush killer!
