| This page is under construction and review by The
University of Florida. All chemicals that are highlighted in green
have labels that clearly allow their use on cucumbers in greenhouses.
Those highlighted in yellow are registered for use on cucumbers and do not
have statements on their labels that prohibit use within a greenhouse. If
you click on the Chemicals Name (in blue type) you will be directed to a
PDF file which can be read by Adobe Acrobat Reader.
