Why Use

  • Kills weeds not the root
  • Selective weedkiller—will only kill broadleaf weeds, not grasses
  • Systemic weedkiller—will kill the entire plant including roots

What to Expect

  • Weeds will show signs of distortion (twisting) in the leaves and stem after a couple of weeks—depending on the local growing conditions
  • Following this the weeds will then die over the coming weeks


Resolva Lawn Weedkiller contains Mecoprop-P and Dicamba.  Use plant protection products safely. Always read the label and product information before use.

When to Use

  • Resolva Lawn Weedkiller Extra Concentrate should be applied from April until the end of September on lawn weeds that are actively growing
  • Do not apply treatment during windy conditions so that spray does not drift onto other plants.


Where to Use

For use on unwanted vegetation

  • Do not use on newly sown lawns for at least 6 months after establishment
  • For maximum effect spray when the weeds have adequate leaf area to absorb the weedkiller spray
  • Apply when weeds are actively growing and soil is moist
  • Control may be reduced if rain falls within 24 hours of application
  • Must not be used for purposes or in a manner not provided for on the label


How to Use

Always read the label fully before use

  • Use a clean knapsack, sprayer or watering can fitted with a fine rose
  • Mix well before use
  • Loosen the measuring cap slightly and gently squeeze the bottle until the required volume is achieved
  • Apply Resolva Lawn Weedkiller Extra Concentrate at rate of 50ml in 2.5 – 5 litres of water to cover 25 sq.m covering weeds evenly
  • Wash equipment thoroughly after use
  • 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

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 die completely and remove them before allowing pets back into the area. This is because weeds that are normally avoided will taste differently 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 Lawn Weedkiller Extra Concentrate is for use on lawns only , and is therefore not recommended for other areas. We recommend Resolva 24H® or Resolva Xtra Tough for total weed kill, including grasses.

Q. When can I sow lawn seed after using Resolva Lawn Weedkiller Extra?

A. Resolva Lawn Weedkiller Extra does not leave a residue in the soil. As soon as the weeds have died completely, re-seeding can take place.
