Weed Control for Tropical cropping systems - 2015

by Dr. Joe DeFrank

  On March 20, 2015, Dr. Joe DeFrank made a presentation in the seminar series for the Department of Tropical Plant and Soil Science (UH-Manoa) titled: Weed Control in Tropical Cropping Systems.  The topics covered in this presentation highlight Dr. DeFrank's 32 year of work in Tropical Weed Science at the University of Hawaii.  Topics were selected to demonstration several concepts in weed control that maximize the effectiveness of herbicides and incorporate the use of solar energy for weed control through the on-site production of mulch.  Topics discussed include:

  1. Weed control in vegetable crops: Conventional herbicides, & living mulches.

  2. Azolla – living aquatic mulch for wetland taro.

  3. Light exclusion with geotextile fabrics – weed control for organic farmers.

  4. Mow & Blow turning chemical fertilizers in to mulch for orchard crops.

  5. Weed control in potted ornamentals with fortified mulch.

  6. Weed control in warm season turf with and without herbicides.

  7. Establishing native plants on roadways to exclude invasive species.
