How to Manage Pests

Pests in Gardens and Landscapes

Bulb mites (Spinach crown mites)—Rhizoglyphus spp.

Bulb mites are shiny, creamy white, bulbous mites that range in size from 0.5 to 1 mm long. They have four pairs of short brown legs and look like tiny pearls with legs. They generally occur in clusters.

Damage

Bulb mites penetrate the developing leaves and distort the growth.

Solutions

Rapid crop rotation fosters the survival of mites on leftover vegetation. After harvest, clear all vegetation to allow organic matter to decompose; this reduces populations of the mite. Flood irrigation or heavy rains during the winter may reduce mite levels in the soil.
