![]() Dry soil conditions, extended leaf wetness and low nitrogen levels in soil are the primary drivers of the disease. The most important turfgrass diseases of Seashore paspalum include: FOLIAR DISEASESĬonditions promoting disease: This is one of the more prevalent and damaging disease of Seashore paspalum. Proper disease diagnosis and management require a thorough examination of the site, knowledge of relevant past and present environmental conditions, in-depth knowledge of plant species biology, site management history, pathogen life cycles and epidemiology, and an orderly series of tests to determine possible causes. Utilizing a resistant cultivar (host), using chemicals to destroy the pathogen, or altering the environment will result in disease control. Disease management is based on the elimination of any one of these factors. If a susceptible host and organism are present, a disease will develop only if moisture and temperature conditions are favorable for that organism to infect. In order to have a pathogenic disease, three factors must always be present: (1) a susceptible host, (2) a parasitic organism, (3) environmental conditions that are favorable to the pathogen. Pathogenic diseases can be caused by differ classes of pathogens such as fungi, bacteria, viruses, phytoplasma, mollicutes, and nematodes. However, turfgrass stands can be injured and damaged by biotic (living) and abiotic (non-living) agents. Diseases on these turfgrass species are the exception and not the rule. Seashore paspalum turfgrass swards will grow at the top of their genetic potential as long as nutrients, moisture, light and favorable temperatures are provided.
