Two-Spotted Spider Mite (Tetranychus urticae)

These tiny arachnids thrive in warm, dry conditions and feed on the underside of Loganberry leaves, injecting toxins that cause stippling. The fine webbing is a characteristic silk structure used by the mites to create a protective microclimate for their colonies.

Very Common

Spider Mite Infestation (Tenuipalpus spp.)

While less common than Two-Spotted mites, other eriophyid species can cause fine silken threads and leaf distortion on Rubus canes. This often occurs during periods of heat stress in the Loganberry canopy.

Common

How to confirm: Inspect the very tips of new growth for tiny, translucent or reddish bumps that move slowly.

Anthracnose (Colletotrichum spp.) - Secondary Effect

While primarily causing dark lesions on canes and fruit, severe Anthracnose can weaken the plant's immune system, making it more susceptible to secondary pest outbreaks like spider mites. The webbing itself is not caused by the fungus but indicates a compromised plant.

Common

How to confirm: Check the base of the canes for sunken, dark, circular lesions or 'cankers'.

2 Prune and remove any heavily infected canes or fruit to reduce the fungal spore load and prevent further spread.
3 Improve air circulation around the plant and avoid overhead watering to minimize the humid conditions that favor Anthracnose.
