Life after methyl bromide: New fumigant, fumigant blend buoy optimism but require more management

摘要

The recently registered fumigant, Paladin, offers growers another option to help control soilborne pests. Like nearly all soil fumigants, the product, which contains the active ingredient dimethyl disulfide, carries a host of Environmental ProtectionAgency requirements that must be met before and during application. Among those are applicator stewardship training, a fumigant management plan and buffers. But Paladin also has what the registrant, Arkema Inc., describes as a distinct garlic-like odor that continues to be an issue with some. About two years ago, Stanley Culpepper, a University of Georgia weed scientist; Perry Fuller, manager of the TriEst Ag Group Inc., in Tifton, Ga.; and another colleague began exploring soil fumigant blends.
