Fungus gnats and shore flies can quickly build up in the greenhouse during spring production. Warm, wet conditions favor their development and with their short life cycle, it doesn’t take long for populations to increase. While adult fungus gnats are primarily a nuisance, the larvae feed on plant roots and stems, allowing soil-borne pathogens to enter and cause disease. Shore flies (adults and larvae) don’t typically feed on plant tissue – instead favoring algae or decaying organic matter – but the adult fly is known to effectively vector several soilborne pathogens, such as Thielaviopsis, Fusarium and Pythium spp.

Pest Lifecycles Disrupted
Citation^® insect growth regulator (IGR) can help control fungus gnats, shore flies and dipterous leafminers by preventing them from reproducing. As an IGR, Citation:

• Disrupts normal larva growth and development
• Interferes with the formation and release of essential insect molting hormones
• Breaks pests’ lifecycles so they are unable to advance to the next stage of development and subsequently die

​​​​​​​Citation is an effective option for use in an integrated pest management program. It has proven to be compatible with many beneficial insects and can be applied during plant propagation. There has also been no phytotoxicity observed at labeled rates.
