by Dr. Joe DeFrank, PhD. Professor Emeritus University of Hawaii, CTAHR, UH-Manoa
On September 15, 2021, Dr. Joe DeFrank made a Zoom-presentation to the PEPS/TPSS 481 Weed Science class and provided a comprehensive description of yellow and purple nutsedge biology and how to use this information in a management protocol. A related discussion included methods of rotational cover crop termination using crimping and tarping to prepare a no till planting site compatible with organic farming practices.
Topics covered:
Biology of yellow and purple nutsedge as it relates to tuber dormancy, a survival strategy.
Three methods of nutsedge management: dry cultivation, grow and herbicide kill and IPM approach.
Solar heated drip irrigation for accelerated nutsedge tuber purging.
Turn the Page Farming: no till farming without herbicides.
