Abstract
Data from experiments conducted at one location in 1980 and two in 1981 showed that MH residues were greater on flue-cured tobacco after application of a K-MH (potassium salt of MH) formulation than of a DEA-MH (diethanolamine salt of MH) formulation at the same rate of active ingredient. On cured lamina mean residue values from K-MH for the two locations in 1981 were 48 % and 61 % greater than those for DEA-MH. There was no apparent loss of residue for either formulation during the curing process. Sucker control was less efficient with the DEA-MH than with the K-MH formulation and was associated with the level of residue in the leaf.
