Sciarid Fly Control

Sciarid flies (also known as fungus gnats or fungus flies) damage plants by transferring fungal diseases from diseased to healthy plants. The larvae also cause damage by feeding on the roots, root hairs, rootlets, and tender root, stem and leaf tissue. Later instars may even feed on plant stems.

Young plants that are kept humid and well-watered are particularly at risk. House plants are common targets of the sciriad fly, as are Cyclamen, Fuchsia, Pelargonium and poinsettia.

Our sciarid fly control contains the insect parasitic nematodes Steinernema feltiae. After administration, the nematodes actively search for and penetrate the prey, after which they excrete bacteria, killing the prey.

Identifying Sciarid Fly Damage

The main impacts of sciarid fly damage are poor plant health, wilting (particularly on hot days) and at times, total plant death. Young plants are more susceptible to damage than older established ones.

On some plants, larvae may feed on leaves that rest on the soil – this can cause holes to appear in leaves which may look similar to the damage caused by slugs. The adult flies can become a nuisance indoors.

What is Biological Sciarid Control?

Biological controls are non-chemical treatments that rely on the natural enemies of pests. In the case of sciarid fly control, the enemy is the nematode, specifically, the species Steinernema feltiae.

Steinernema feltiae are microscopic worms that actively seek out the sciarid fly larvae, feeding and multiplying inside them, then infecting them with a bacterium. Once infected, the sciarid larvae will stop feeding and die. The nematode will then go on to seek out more, repeating the cycle.

Biological sciarid control is a highly effective, safe treatment that can be used on turf as well as ornamentals. It is safe for pets and other wildlife and the perfect choice for organic gardeners.

Storage

• After delivery, please check the product for abnormalities and report any issues to Agrigem within 24 hours.
• As this product is perishable, it is preferable to use immediately after receipt. If not applying the same day, this will need to be refrigerated and used by expiry date.
• To store in refrigerated conditions, please remove the outer packaging to ensure good air circulation around the tray(s).
• If the product is stored longer and/or differently to the above, Agrigem will not be liable for loss of quality.
• Use the entire pack and do not store stock solution or diluted product.

Application

Nematodes should be applied when the soil temperature is above 10°C or at any time for houseplants. Apply early in the morning or early in the evening for best results.

• Do not apply in sunny weather as nematodes are UV sensitive.
• Ensure you apply to moist soil using a watering can or sprayer. Remove any filters before use and follow the diluting and application instructions.
• Avoid over watering the area after application, keep lightly moist.
• If the pest problem is already well established this may take multiple applications a few weeks apart.
• Water the soil thoroughly after application to wash the nematodes into the soil and keep the soil moist for at least two weeks after application.
