Control 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.

Pesticide application residue research underway (starting Feb. 2015)
In collaboration with Dr. Qingxiao Li (MBBE) and 2 golf courses, we are conducting a pesticide application residue research. Multiple patches are attached to the applicator when chemicals are sprayed, and these patches will be analyzed for chemical residues. We thank golf courses participating in this 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 effects of this turf renovation method on pest and beneficial insects, pathogens, and soil food webs in turf systems.
