FAO "old procedure" specifications for 2,4-D and variants have been developed and published (1984 for the TC - (1/TC/S/F (1992)), sodium salts (1.1Na/TC/S/F (1992)) and 1992 and 1994 for the esters (1.3/TC/S/F (1992)). 2,4-D was qualified as a candidate for conversion of an old
Most cases of groundwater contamination involving phenoxy herbicides such as 2,4-D have been associated with mixing/loading and disposal sites. Caution should be exercised when handling 2,4-D pesticides at such sites to prevent contamination of groundwater supplies. Use of closed systems for mixing or transferring this pesticide will reduce the
