Pest - FUNGUS GNATS
Fungus gnats are a problematic pest, especially in young plants. They can cause damage to seedlings, rootstock, and cuttings of many plant species. They are most often found in moist organic environments.
Fungus gnats go through seven developmental stages: egg, four larval stages, pupa, and adult. Adults are noticed when they appear in large numbers. Eggs are deposited in the soil, where all developmental stages take place. Larvae generally eat rotting plant material, algae, and fungi that are present in or on the soil.
Fungus gnats can cause both direct and indirect damage. Direct damage occurs when the larvae graze on the plant's roots. Indirect damage occurs when the adults spread diseases (fungal spores and plant viruses) or pests such as mites and harmful nematodes.
Biological control of fungus gnat larvae is possible with the Koppert products listed below.
