Recently, there is an increase in the number of calls to our UF/IFAS Extension office. The clients are concerns about the yellowing of their Bahiagrass. Bahia is known to be one of the hardiest turfgrasses available to us in Central Florida. Bahia can bounce back quickly when affected by insects, pests and extreme drought conditions.
Bahia yellowing has caused us to observe the roots of Bahia grass under the microscope. We found spores of Pythium pathogen growing on the roots of yellowing bahiagrass. In previous observations we found Take All Root pathogens on yellowing bahiagrass. It is important to note that yellowing bahiagrass does not always mean that there is a disease pathogen present. We are in the rainy season and most turfgrasses prefer a well-drained soil, and lawn flooded for prolong period will cause roots to be dysfunctional. Dysfunctional roots will not be able to uptake nutrients such as nitrogen which important in keeping plant green. No treatment is needed Bahia grass will bounce back.
