Fungal diseases are among the most common threats to bonsai health — and one of the easiest to underestimate. By the time symptoms like powdery mildew, black spot, sooty mould, or root rot become visible, the infection is often already well established. Our range of fungicides and wetting agents gives you the tools to prevent outbreaks before they start and treat them effectively when they do.
Systemic and contact fungicides that target a broad spectrum of fungal pathogens affecting bonsai and ornamental trees. Suitable for preventative seasonal spraying as well as active treatment during outbreaks.
Improve the coverage and absorption of fungicide sprays with a dedicated wetting agent. Wetting agents reduce surface tension, ensuring your treatment penetrates foliage and reaches the fungal infection more effectively — especially useful on waxy or dense-canopied trees.
Regular preventative treatment during humid or wet seasons is the best defence. Shop our full range below.
