Low Input Turf

By Ning Zhang and Jing Luo, Rutgers University

Summer patch is a common and destructive root disease of fine fescue grasses. It causes root, crown and stem rot that develops during periods of summer stress (Smiley et al., 2005). The known causal agents of summer patch are two fungal species, Magnaporthiopsis poae and M. meyeri-festucae that belong to the order Magnaporthales (Luo et al., 2017).

Summer patch is a common and devastating fungal disease of fine fescues. Many major turfgrass species are susceptible to summer patch. A more thorough description of summer patch disease and the causal agents have been previously discussed. As mentioned in the articles, summer patch can be caused by several closely related fungal species and their microscopic structures are similar making it difficult to diagnose and apply targeted treatments.

Thanks to NTEP-DB 1.0 [1], the relational database we created for the National Turfgrass Evaluation Program (NTEP), obtaining turfgrass cultivars' data will soon be much easier. In addition, a user-friendly web application by U-Spatial allows homeowners, researchers, and other stakeholders to extract meaningful information from NTEP data in a variety of formats.  For example, retailers can learn the best cultivars to stock in different store locations around the country.

Hard fescues are often utilized for their low input maintenance requirements, but are susceptible to heat stress. With annual temperatures rising, there is both a demand for more heat-tolerant hard fescue turfgrasses and a demand for effective strategies for assessing phenotypic traits to select or screen for heat-tolerant genotypes in hard fescue.

A team of scientists at Purdue University, Oregon State University, and University of Minnesota investigated establishment differences among the fine fescue taxa and at the same time investigated the influences of different levels of nitrogen fertilizer and including clover. The objectives were to investigate differences among fine fescue taxa and determine optimal N fertility or clover-inclusion programs for fine fescue taxa during establishment for future low-input sites.
