Resolva Xtra Weedkiller Ready to Use is a non-glyphosate systemic weedkiller. It is extremely effective on vegetation and roots of persistent broadleaf weeds in lawns such as daisies, dandelions, clover, buttercups and dock leaves. Resolva Xtra is selective and systemic, and will only kill weeds and their entire root, but not grasses. By killing on contact, it therefore acts by desiccation of target weed.

  • Glyphosate-free
  • Kills weeds, not lawns
  • Will kill entire plant including roots
  • Controls annuals, perennials and difficult broad-leaf weeds
  • Ready to use formula for quick use

Why Use

Weeds can be a problem around the garden especially if you let them grow. They will compete for the same space and nutrients as your plants and if left untreated they will create seedlings and spread further. Resolva Xtra Weedkiller deals with tough weeds without damaging lawns, whilst also being glyphosate-free. It’s a selective and systematic weedkiller, killing only the whole weed and not the lawn. Weeds that can be controlled with Resolva Extra Weedkiller are:

  • Daisy
  • Thistle
  • Dandelion
  • Clover
  • Buttercup
  • Dock

glysophate free

We have created a Glyphosate free formula for gardeners looking for a greener more natural approach to controlling their garden weeds but still want results.

What to Expect

before and after resolva xtra

After spraying, weeds may grow vigorously at first. This means the weedkiller is working and the weed will “outgrow” itself, then turn yellow and die completely.

Our clever formulation can also be used on grass as it leaves your lawn undamaged as it only targets the weed and its root.

To keep weeds at bay, repeat applications as necessary through the season.

People and animals can enter the treated area once the sprayed has dried.


When to Use

resolva xtra before and after treatment

Use Resolva Xtra Weedkiller between April and September,  when weeds actively grow.

How to Use

  • Always read the label fully before use
  • Shake well before use
  • Turn sprayer nozzle to required sprayer pattern
  • Spray weed leaves as a light spray directly at weeds until they are wet, but avoiding run-off
  • Turn nozzle to “X” position after use and before storage
  • Scorching of grass can occur if more than one squeeze is applied to a given area
  • Re-treatment may be necessary for well established or difficult to control weeds
  • Allow an interval of at least 6 weeks between treatments
  • Following spraying, do not cut grass for at least one day after treatment and ideally leave the sprayed area uncut for as long as possible
  • The first four mowings of treated grass must be composted for six months before use as a mulch.
  • For maximum effect, spray when the weeds have adequate leaf area to absorb the weedkiller
  • Apply when weeds are actively growing and soil is moist, at least 5 days after mowing
  • Control may be reduced if rain falls within 24 hours of application
  • Must not be used for purposes or in a manner not provided on the label.

How to use the Power Pump

Simply pump the handle for up to 20 minutes for over 10 minutes of controllable spraying. Furthermore, this 5L weedkiller will cover 250m², equivalent to 25 parking spaces.

Frequently Asked Questions

Q. Can my pets go into the treated area?

A. For non-grazing animals allow product to dry before allowing pets back into the area. For grazing animals allow weeds to fully die before allowing pets back into the area. This is because weeds that are normally avoided will taste different due to masking of flavours, and as a result, grazing animals may attempt to eat them. Alternatively, treat half the area, then swap over after 6 weeks.

Q. Can I use this on other areas in my garden?

A. Resolva Xtra Ready To Use Weedkiller is for use on lawns only , and is therefore not recommended for other areas. We recommend Resolva 24H or Resolva Xtra Tough for total weedkill, including grasses.

Q. When can I re-sow lawn seed after using Resolva Xtra Ready To Use Weedkiller?

A. Resolva Xtra Ready To Use Weedkiller does not leave a residue in the soil. As soon as the weeds have fully died it is fine to re-seed.
