Woody galls form on lower stems and root tissue. If the gall encircles the lower stem or main roots, the plant may be killed. Do not plant nursery stock showing these symptoms. Setting existing plant in raised beds may prolong their life. Sterilizing the soil prior to planting is helpful only if the organism is not introduced on the transplant.
Plants become unthrifty and die due to plugging of the water and nutrient conducting vessels.
Occurs mostly in West Texas. Compost or sterilize gin trash if it is being used as mulch. Knots or galls occur on smaller roots limiting the development of the root system. Do not plant stock that is infected. Sterilize soil if plants must be planted in infested areas.
