Diuron Crop Safety – 2010

Research Summary Abstract

Data in this report were generated to expand registered uses of diuron on ornamental species. Diuron rates in these experiments ranged from 0.5 to 16 lb ai/A. Direx 80DF and Karmex 80WP were tested on 26 plant genera or species between 1978 and 2002. Two bulb species exhibited no injury with soil applications after planting: Lilium sp and Narcissus sp. Two species exhibited mortality with over the top applications: Quercus palustris and Washingtonia robusta. The remaining species were tested either as directed sprays or under the greenhouse bench applications. More information is needed on these crops because only 1 or 2 trials were conducted.
