The objective of this study was to evaluate fungicides for control of root rot caused by the fungus, Phymatotrichopsis omnivora. The experiments were done in two production areas of Texas (San Patricio and Tom Green Counties)using drip-irrigated fields with a history of severe root rot. In separate experiments, the fungicides were applied to the lower stems of plants or were injected into drip irrigation tape when plants were flowering. Fifteen systemic fungicides in several fungicide classes were evaluated. Also, two seed treatment fungicides were compared with a stem application of propiconazole when plants were flowering. With stem applications, disease incidence two months after application was 29% with propiconazole at 2 lb a.i./A, as compared with 49% for the control, and 45-59% for the other fungicides. There was no evident root rot control when fungicides were injected through the drip tape.
