Fusarium Race 4: Management Recommendations for Growers

Race 4 of Fusarium oxysporum  spp. vas infectum has increasingly impacted cotton fields in California’s San Joaquin Valley over the past 5 to 7 years.   During this period a substantial amount of field observations of plant symptoms and disease development patterns have been made, and generalizations learned from these efforts will be summarized, along with considerations for those involved in checking both Upland and Pima cotton plants for disease identification.   In fields where this fungal disease has been confirmed as present in the plants and soil, recommended management considerations have been developed, and will be discussed in this poster.
