A leaflet is available describing the most commonly found garden pests and diseases in Guernsey and the available control methods. This document also includes pesticides that are available for garden use.

When using pesticides ALWAYS READ THE LABEL: USE PESTICIDES SAFELY.

  • Honey Fungus

    • Honey Fungus or Armillaria is probably the most important killer of woody plants on the island and is difficult to control. A separate leaflet has therefore been produced which includes details of control measures and the plant species that are most tolerant of or resistant to the fungus.
  • Japanese Knotweed

    • Japanese Knotweed is the most invasive plant in Guernsey. It spreads rapidly, especially next to streams, out-competing and destroying native plants, flowers and habitats and is difficult to control.
    • Advice on how to control Japanese Knotweed in the garden or using professional herbicides is also available to download.

Please contact us if you require further information.
