Start by unsnapping a holder and removing the wand from the bottle. Then unwrap the hose and pull out the battery tab insert. The red plug into the knob on the cap. And turn the knob to on.

Continuous spray sure shot wand extends 2 ft. no bending, pumping or hand fatigue and no more bending over to kill weeds. Use shield to contain the spray and help protect nearby plants from damage. Ideal for targeting weeds in garden and landscaped beds. Can also be used on driveways, sidewalks and patios.

Most Roundup® Weed & Grass Killer products deliver visible results in a few hours, though some take a little bit longer. For Roundup® Max Control 365, it takes 12 hours to see visible results, but the trade-off is year-long hassle-free weed control.

Carefully pour the refill into your original ready-to-use container. That's it! No need to add water - just the product itself.

To effectively kill weeds, it's recommended that you spray 30 minutes to an hour before rain, if not earlier, depending on the brand you choose. After it rains, wait for the leaves to dry out before spraying, or the herbicide may be washed away.

Glyphosate is a non-selective herbicide, meaning it will kill most plants. It prevents the plants from making certain proteins that are needed for plant growth. Glyphosate stops a specific enzyme pathway, the shikimic acid pathway. The shikimic acid pathway is necessary for plants and some microorganisms.

Roundup is the brand name for an herbicide containing the active ingredient glyphosate. Glyphosate is a nonselective weed killer, meaning it can kill most plants on contact within days or weeks. Agricultural workers often apply glyphosate by spray to large areas of crops.

EPA has determined Roundup has: No risks of concern to human health from current uses of glyphosate. No indication that children are more sensitive to glyphosate. No evidence that glyphosate causes cancer in humans. No indication that glyphosate is an endocrine disruptor.

EPA scientists performed an independent evaluation of available data for glyphosate and found: No risks of concern to human health from current uses of glyphosate. Glyphosate products used according to label directions do not result in risks to children or adults.

Most research shows that the length of time that Roundup stays active in the soil in many cases is less than one year, but the range depends largely on environmental factors and the amount of the chemical that a person applies in a particular area.

Mix 200 mL of Roundup Advanced® Concentrate with 1 L water. Apply the mixed solution at 100-200 ml/m2. For annual weeds, use at the lower rate. For perennial and more established weeds, use at a higher rate.

Use up to 6 oz (170 g) of Roundup per 1 US gal (3.8 L) of water for small crops. For smaller crops, you can use Roundup in amounts from 2.5 ounces (71 g) to 6 ounces (170 g) per 1 gallon (3.8 L) of water. Always check the manufacturer's directions and note the necessary Roundup amount in ounces (or grams).
