Dr Hydro - Fungus Gnat

Dr Hydro - Fungus Gnat


Dr Hydro Fungus Gnat Root Drench is a potent solution designed to eliminate fungus gnat maggots while ensuring plant safety. Upon application, it swiftly kills the maggots, allowing easy trapping of adult gnats using sticky traps near the growing media. Despite its high reactivity, it transforms into plant-safe nutrients within hours, making it suitable for organic crops. The product emits a strong odour similar to 'rotting eggs', which dissipates quickly; ensure proper ventilation when used in enclosed spaces like greenhouses, polytunnels, or indoors.

Application Instructions:

  • Wear personal protective equipment (PPE) before opening, including a face mask with a Type B filter, eye protection, gloves, coveralls, and appropriate footwear.
  • For best results, let the growing media dry for two days before application.
  • Mix 50mL of concentrate with 1L of tap water and drench the surface of the growing media until saturated.
  • Reapply 7-10 days later to target any new eggs.

Safety Data:

  • Do not use as a foliar spray or store diluted product.
  • Only mix with tap water.
  • Approved for use on organic crops under EU Regulations (EC) No 889/2008.
  • Store away from direct sunlight and extreme temperatures (4-30°C).
