Minor Pest Title

Spider mites (Tetranychus spp; cotton red mite Oligonychus gossypii)

Minor Pest Description

Spider mites feed on the lower surface of leaves. Adults are about 0.6 mm long. As a result the leaf surface appears tan or yellow and the upper surface has a speckle or mottled appearance. A close inspection of the lower leaf surface shows the mites as tiny moving greenish or reddish speckles. Heavily infested leaves turn yellow, curl up, dry and are shed. Mites produce a large amount of webbing. In heavy infestations a fine web may cover the leaves. Plants may die when infestation is severe, particularly in hot dry conditions.


Minor Pest What to do.
  • Provide good plant growing conditions, in particular enough water; water stressed plants are prone to mite damage.
  • Avoid the use of broad-spectrum pesticides, which kill natural enemies and may result in mite outbreaks.
  • Avoid planting next to infested fields.
  • Sulphur preparations control mites. However, it should be noted that sulphur also kills predatory mites.
