The Florida Department of Agriculture and Consumer Services has registered the fumigant Paladin from United Phosphorus Inc. of King of Prussia, Pa.
In addition, FDACS registered Paladin EC, a fumigant applied through drip irrigation systems.
Both contain the active ingredient dimenthyl disulfide, and both are restricted-use pesticides that can only be applied by a certified applicator, according to the product labels.
The fumigants must be used with an approved VIF, or virtually impermeable film.
UPI recommends using Paladin with chloropicrin at a ratio of 79:21 by weight. The company also recommends use of a pre-plant herbicide to increase the control of small-seeded broadleaves and grasses.
