In an effort to provide weed management tools to growers of a wide variety of nursery ornamental crops this research was undertaken to expand the three pre-emergent herbicide labels:
Category: CropSafety
Clethodim Crop Safety – 2012
Clethodim, a grass herbicide, was first registered in the US as Select Herbicide for ornamental horticulture crops in 1983 with a limited crop list. From 1997 through 2007, the IR-4 Project completed
Mesotrione Crop Safety – 2011
From 2007 to 2011, IR-4 completed 144 trials on Mesotrione SC. The data contained in this report was generated to register uses of mesotrione on and around ornamental horticulture plants
Fluopicolide Crop Safety – 2011
Fluopicolide was registered as Adorn 4SC in the United States in 2008 for control of Pythium, Phytophthora and downy mildew in ornamental plants. State registrations in California and
Halosulfuron Crop Safety – 2011
Since 1995 IR-4 has completed 373 trials with products containing halosulfuron (Sedgehammer, Manage) on 132 crops. The data contained in this report were
Diuron Crop Safety – 2010
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
Simazine Crop Safety – 2010
Princep 80W, 90W, 4G, 4L and Caliber 90 DG were tested on 54 plant genera or species over a sixteen year period (1973- 1989). Data in this report were generated to expand registered uses of simazine
V-10142 Crop Safety – 2010
From 2006 to 2009, IR-4 conducted 293 trials with V-10142 0.5G and V-10142 75WDG (imazasulfuron) on more than 60 crops. This research was undertaken to determine the level of
Oxyfluorfen Crop Safety – 2009
Oxyfluorfen (Goal 2XL) has been registered in the United States since 1979 (Goal 2E) for uses in and around ornamental plants in production nurseries and in landscapes. The label recommends
Clopyralid Crop Safety – 2009
Lontrel (clopyralid) was initially registered in 1998 for ornamental horticulture uses. This initial label contained an extensive list of ornamental horticulture plants where Lontrel could be used without causing
