Summary:
Management of Verticillium wilt of cotton requires multiple tactics. Large scale research was used to evaluate the effects of crop rotation and irrigation rate on susceptible and partially resistant cultivars in a field with Verticillium wilt on cotton yield and quality parameters. It is proposed to conduct a detailed economic analysis on six years of data to determine the economic benefits of these tactics alone and in combinations. This information should provide the template for producers to maximize profitability in fields with a history of Verticillium wilt. Irrigation rate is difficult to optimize. Optimization of irrigation is difficult. Reducing irrigation can minimize disease; however, this may also reduce yield. Over irrigation can aggravate Verticillium wilt, resulting in yield loss as well as wasting irrigation resources. It is proposed to test for a relationship between soil moisture/temperature, irrigation rate, soil density of V. dahliae, and Verticillium wilt incidence and yield. Sensors to monitor soil moisture and temperature will be deployed in fields infested with V. dahliae where cultivar, irrigation rate and crop rotation studies are being conducted, and locations in Texas and Alabama (totaling 7-8) were additional cultivar trials are being conducted. At all of these sites, the collected information (pathogen data, environmental data, irrigation rate and frequency, cultivar type (susceptible or partially resistant)) will be used to develop a model predicting Verticillium wilt incidence and yield. The model will be validated by additional field information of a similar nature, collected at producer fields (not used in the model development).
Objectives: Objective 1) Determine the cost/benefit of cultivar selection, pumping capacity, and crop rotation for cotton grown in a Verticillium wilt field. Objective 2) Determine the relationship between soil temperature, soil water, V. dahliae density, and irrigation (type, frequency, amount), to Verticillium wilt incidence, and yield in Texas. Objective 3) Determine the relationship between soil type and textures, soil temperature, soil water, Verticillium wilt incidence, and yield in northern Alabama. Objective 4) Determine similarities between Verticillium wilt predictions based on the measured inputs for the two states which may give insight into robust management options. |
