Pests Guide
Small holes or pits in leaves that give the foliage a characteristic “shothole” appearance.
The pest responsible for the damage is a small (1.5–3.0 mm) dark colored beetle which jumps when disturbed; the beetles are often shiny in appearance.
Young plants and seedlings are particularly susceptible; plant growth may be reduced
If damage is severe the plant or young seedlings may be killed
Floating row covers may have to be used prior to the emergence of the beetles to provide a physical barrier to protect young plants
Plant seeds early to allow establishment before the beetles become a problem - mature plants are less susceptible to damage
Catch crops may provide a measure of control - cruciferous plants are best
Application of a thick layer of mulch may help prevent beetles reaching surface
Application of diamotecoeus earth or oils such as neem oil are effective control methods for organic growers
Rotate crops.
