Doff Knock Down Super Strength Weed Killer - 6 x 100ml Sachets

The exact dilution can vary slightly, but generally, one 100ml sachet is mixed with 4-5 litres of water in a garden sprayer. Always refer to the instructions on the product packaging for precise dilution rates.

No, this weed killer contains Glyphosate and is designed to kill all plants it contacts. It is not suitable for use on lawns or near desirable garden plants.

For best results, apply when weeds are actively growing and have sufficient leaf area to absorb the spray. Avoid application during drought, frost, or if rain is expected within 6 hours.

Visible results typically appear within a few days to two weeks, depending on the type of weed and growing conditions. The product works systemically, killing the weed down to the root.

It means the active ingredient is absorbed by the leaves and travels through the plant's vascular system to the roots, ensuring the entire plant is destroyed and less likely to regrow.

It is strongly advised not to use this product near vegetable patches or any edible plants, as it can contaminate them and render them unsafe for consumption, as well as killing the plants themselves.

The product information does not specify if the sachets are biodegradable. It is best to dispose of empty sachets responsibly according to local waste disposal guidelines.

Ensure the correct dilution ratio was used and that the spray was applied directly to the weed foliage. Reapply if necessary, ensuring no rain is forecast for at least 6 hours. Check that weeds were actively growing at the time of application.

Immediately rinse the affected plants with plenty of water. Recovery depends on the amount of product absorbed. Future applications should be done on calm days and with careful aim.

Ensure the product was fully dissolved in water and that the sprayer was rinsed thoroughly after previous use. Check the sprayer's filter for blockages.
