Dr Hydro Fungus Gnat Root Drench- 500ml

Product no.: DHF500
Price incl. VAT, plus delivery

Dr Hydro Fungus Gnat Root Drench is a plant-safe soil sterilant that instantly kills fungus gnat maggots!  You can then catch the flying adult gnats with sticky traps positioned close to the growing media.  The product is highly reactive but breaks down to plant-safe nutrients after just a few hours of application.  For this reason it is authorised for use on organic crops.


  • When mixing and spraying use suitable face masks, eye shields, gloves, coveralls and footwear. Your face mask should be fitted with a type B filter.
  • Add 50mL of the concentrate to one litre of tap water. Add to a watering can and drench the surface of the growing media. Apply enough diluted product to saturate the growing media. For complete control apply again 7-10 days later (to kill any eggs laid after the first application).

Safety Data:

  • Do not apply as a foliar spray. Do not store diluted product. Never mix with anything other than tap water.
  • Suitable for use on organic crops; covered by EU Regulations (EC) No 889/2008. Store out of direct sunlight and away from extremes of heat (4-30°C).
