Timorex Gold is a natural botanical broad-spectrum fungicide with preventative and curative activity based on the plant extract of Melaleuca alternifolia.  As a plant extract, the active ingredient is based on more than 100 compounds produced by the tea tree plant.

The components of this plant extract provide multiple modes of action mechanisms thus controlling a broad spectrum of ascomycete and bacterial plant diseases like Powdery Mildew, Early Blight, Botrytis and more, in a wide range of vegetable and fruit crops.

Benefits of Timorex Gold

  • Multiple modes of action
  • Control of a wide range of plant pathogens, particularly bacterial and ascomycete diseases
  • Resistance management
  • No residues; no MRL
  • Zero toxic load
  • No measurable affect on beneficial insects and bees
  • Easily adapted into sustainable and IPM practices
  • Certified for organic agriculture
  • Non-persistent in the environment
  • Minimal PPE required

Modes of Action

The active ingredient of Timorex Gold is based on the extract of the tea tree plant (Melaluca alternifolia) containing over 100 compounds.  Some of these compounds work synergistically.; some offer diverse modes of action.

Disruption of the fungal cell membrane and destruction of the cell walls, resulted in lower levels of fungal hyphae within the intercellular space of the mesophyll tissue followed by the loss of cytoplasm, which ultimately causes the death of fungal cells.  The complex active ingredient in Timorex Gold:

  • disrupts cell membranes, causing cell destruction;
  • affects fungal pathogen mitochondria and respiration;
  • appears to interfere with bacterial pathogen virulence by confusing quorum sensing;
  • affects Intrinsic Plant Activity, allowing the plant to focus energy of increased growth and yield;
  • inhibits spore germination in some pathogens and suppresses hyphal growth in other pathogens

Based on the unique modes of action of Timorex Gold, FRAC listed the plant extract – and active active ingredient in Timorex Gold – in a new classification:  “Cell membrane disruption” (Code 46).  Timorex Gold is an effective tool for resistance management programs.

Intrinsic Plant Activity

The complex active ingredient in Timorex Gold impacts the plant’s defense processes, reducing the energy they plant requires to build its defense response.  When a plant is attacked by disease, it activates its immune system, building crystalline structures inside cell walls.  When Timorex Gold is used, the attacked plant diverts energy to growth and yield instead of defense processes, demonstrated by reduced crystalline structures in the images below.
