Is this a Minor Pest?: 
Yes
Minor Pest Title: 

Spider mites (Tetranychus spp.)

Minor Pest Description: 

Spider mites feeding on bean plants may cause reduction in plant growth, flowering, number and length of pods, and number of seeds per pod. Damage is most severe when mites attack young plants. Mite damage may be particularly severe during the dry season.

Minor Pest What to do.: 
  • Avoid planting next to infested fields.
  • Avoid frequent use of broad-spectrum pesticides, particulary pyrethroids; this may lead to spider mite outbreaks.
  • Use overhead irrigation or wash plants with a strong jet of water to knock off mites and to destroy their webs. Be sure to spray the underneath of the leaves. However, this should be done early in the day to allow the foliage to dry. Wetness of the foliage for an extended period is conducive to development of fungal diseases.
