Roundup® Total Optima Weedkiller Concentrate is completely glyphosate-free and comes in the classic green packaging you know and trust. This powerful formula is perfect for targeting weeds in flower beds, vegetable gardens, and all over your outdoor space.

Once sprayed the active ingredient – pelargonic acid – starts working immediately, gives results in 3 hours and breaks down in soil naturally. Weeds will be dead in under 24 hours (if used in optimal conditions), leaving the area ready for replanting in just 3 days.

Reduce plastic by purchasing a concentrate, this also allows for a larger coverage area of 220m².

How to use
Use in a pressure sprayer only. Wear gloves and enclosed footwear.

Work out the amount of concentrate required using the table on-pack. Measure and mark out large areas before application.
Fill sprayer with half the water required, then add the required quantity of concentrate (use the measuring cap).
Add the remainder of water and mix thoroughly before applying. Spray the weeds, ensuring good coverage of the leaves.
Use the mixture immediately or soon after mixing. Only make as much as you plan to use within 2 hours. If left standing for more than 30 minutes shake the sprayer before using.
Wash equipment thoroughly with water immediately after use, three times with water and drain the sprayer on areas on to bare soil not intended to bear vegetation.
Keep children and pets away from treated areas until spray has dried.

Where to use:
Used to kill weeds on flower beds, borders, vegetable patches, around roses, shrubs, hedges, greenhouses and along fences. Ideal before cropping and ground clearance before cultivation.

Can be used to clean up weedy ground before planting vegetables, flowers, bushes and trees, and to renovate overgrown areas.

For the control of weeds around ornamental garden plants, trees and in areas not intended to bear vegetation.

Most effective when applied to newly established weeds or those less than 10–15 cm tall.

Do not direct spray or allow spray drift onto cultivated plants and lawn as this product destroys all green plant parts.

When to use:
Apply in warm, calm, dry, conditions during April – November when weeds are actively growing.

Do not apply when there is a risk of frost or drought as weeds will not be actively growing.

Reapply if it rains within 3 hours of application. Reapply 7 to 21 days if required. Maximum 4 applications per year.
