Insects

Fungus gnats are a common greenhouse pest, especially in moist environments found in propagation houses. Gnat larvae infect and feed on organic matter and plant roots, causing root injury and death. Adult are dark and look similar to a mosquito. Larvae are generally found in the top 2-3 inches of growing medium.

Lepidopteran pests are a wide range of insects that include moths and butterflies, and infect most horticultural crops in Canada. Adults are active fliers that are able to suck plant nectar and other fluids, but not chew. Larvae do much of the crop damage with their well-developed mandibles.

Phytophthora blight/crown rot is one of the most destructive field vegetable diseases in many parts of Canada. The pathogen has many hosts – pepper, tomato, eggplant and most cucurbits – and survives on a wide range of crop debris including cucurbits and fruiting vegetables. In wet, warm conditions, the disease develops rapidly with wilting as a common symptom.
