Description

In recent years, an increase in the incidence of bronzing and roughened leaf texture on cabbages grown in southern Alberta has sometimes made the cabbages unacceptable for either the fresh or processing market. This damage is associated with high populations of thrips, tiny insects that feed by rasping and piercing the outer cell layers of the leaves and ingesting the exposed cell contents. The damaged tissue desiccates and allows the entry of disease organisms. When thrips feed, they leave small black specks (fecal pellets) on the injured plant parts.
