ROBUScontrol (Macrocheles robustulus) 50K Loose Tube

ROBUScontrol (Macrocheles robustulus) – Fast-Moving Compost Mites for Fungus Gnat and Shorefly Larvae

Fungus gnats and shoreflies can quietly undermine a crop from below – disrupting roots, reducing vigour, and opening the door to disease. When larvae are already present in the compost, ROBUScontrol brings in an aggressive, soil-active predator that’s built for the job.

Each tube contains thousands of Macrocheles robustulus – a fast-moving predatory mite that targets sciarid and shorefly larvae where they live: in the growing media. These mites don’t wait around. They quickly get to work, hunting through the compost and feeding directly on pest stages before they mature.

ROBUScontrol is especially well suited to propagation units, container-grown crops, and greenhouse production areas where moisture and organic matter attract pests below the surface. It’s best used curatively when infestations are visible, or as a booster to other soil-level biologicals already in place.

Because they operate entirely in the root zone, these mites pose no disruption to crop activity above ground and can be combined with foliar beneficials as part of a full IPM approach.

Best suited to:

• Growers seeing visible signs of sciarid or shorefly larvae in compost
• Propagation zones, plug trays, or pots where outbreaks can quickly escalate
• Crops where soil drenches or sprays aren’t reaching the problem
• IPM programmes looking to reinforce compost-level control

How to apply:

Apply up to 500 mites per square metre, depending on pest pressure. Scatter evenly across moist compost and avoid immediate overhead irrigation. These mites prefer humid, shaded conditions – ideally above 15°C.
