Suppressing bermudagrass in seashore paspalum turf
An emerging management challenge of seashore paspalum turf installations and maintenance in Hawaii in recent years is the infestation of the bermudagrass cultivar that was replaced or common bermudagrass. PI Z. Cheng and Co-PI J. DeFrank continue to receive inquiries from golf courses that use seashore paspalum to develop new grassy weed control options that do not depend on salt applications. This project will address this immediate need of Hawaii's turf/golf industry. An M.S. student who started in August 2016 is working on this 2-year project. Field trials are currently being conducted in UH Manoa Magoon research facility, West Loch Golf Course, and Hoakalei Country Club.
Management of take-all patch (Bermudagrass decline) of turfgrass in Hawaii
In collaboration with 3 golf courses on Big Island, Maui and Oahu, and with industry support from 2 major chemical companies, this applied research project was started in November 2015 to evaluate various fungicide programs against take-all patch (also commonly known as Bermudagrass decline) in both bermudagrass and seashore paspalum turf. Various fungicide rotation programs and combination treatments are included in this field research.
Management of leaf and sheath spot (mini ring) of turfgrass in Hawaii
In collaboration with a golf course on Maui and with industry support, this applied research project was started in June 2015 to evaluate various fungicide programs against leaf and sheath spot (also commonly known as mini ring) in Hawaii's turfgrass system. Seven treatments and an untreated control with four replications each are included in this field research.
Non-chemical "lights-out" turf renovation and weed/pest control
In collaboration with Dr. Joe DeFrank (TPSS), we started this 2-year non-chemical "lights-out" turf renovation and weed/pest control project at Magoon Turf Research Facility in October 2014. In addition to weed suppression, we are also studying impacts of this turf renovation method on insects and soil food webs in turf systems.
