Insects

Grape phylloxera is a small, aphid-like insect that feeds on grape roots, stunting or killing vine growth. Above ground feeding occurs mainly on the foliage with leaf galls (hollow, pea-sized swellings) forming on the underside of leaves. The insect also causes indirect damage to susceptible grapevines, and grape phylloxera galls also cause defoliation and retard shoot growth.

Brown marmorated stink bug (BMSB) is on its way to Canada. Originally from Asia, this species was introduced to North America in the mid 1990s. An excellent hitchhiker, BMSB attacks a wide variety of plants, has no effective natural enemies in North America and has already been detected in 39 states. To date, BMSB has been intercepted coming into several Canadian provinces on imported goods and in vehicles.

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.

Diseases

Downy mildew is a serious disease affecting grape crops in Canada. Caused by a fungus-like water mould (Pseudoperonospora cubensis), downy mildew spreads rapidly once established, causing a significant impact on fruit quality and yield.
