Roundup is a brand name for a glyphosate herbicide produced by Monsanto Corp. It kills weeds without harming grass or other vegetation, making it popular with farmers and homeowners alike. Roundup is manufactured in both ready-to-use bottles and large, concentrated bottles that can be diluted after purchase. The concentrate produces more ounces of finished spray than premixed bottles, making it more popular and cost-effective.
Things You'll Need
- Breathing mask
- 1-gallon garden sprayer
- Roundup concentrate
- Measuring spoons
Determine what strength of Roundup is necessary to kill the weeds on your property. Delicate plants such as lantana can be killed with a weaker solution, while hardier plants like beachgrass require a strong concentration of herbicide for best results. Check the Roundup product label for a complete listing of appropriate concentrations.
Put on protective equipment before mixing Roundup. Heavy work gloves and goggles should be worn to prevent chemical burns, and a breathing mask is necessary to keep from inhaling minute chemical particles.
Fill a 1-gallon sprayer with clean, warm water. Use the measuring spoons to pour the specified amount of Roundup into the sprayer. For example, killing honeysuckle requires a 0.8 percent concentration of Roundup. It takes 1 oz., or 2 tbsp., of Roundup mixed with a gallon of water to produce a 0.8 percent solution.
Place the lid on the sprayer and shake gently back and forth to combine. Spray weeds early in the morning, so the product has a chance to penetrate to the root of the plant during the heat of the day. Spray the weeds again in a week if they still show signs of life.
