The HPLC determination of residues of maleic hydrazide in cloves of garlic bulbs following foliar application
1991
Cessna, A.J.
A method was developed for the extraction and HLPC analysis of the plant growth regulator maleic hydrazide (MH) from garlic bulbs. Recovery of MH from fortified garlic tissue was 75.8(+/- 6.1)% at the 1 and 2 mg kg-1 fortification levels. MH residues were determined by HLPC in cloves of garlic bulbs following treatment at three sites in southern Ontario with foliar applications at 3.75 kg ha-1. MH residues in the cloves were in the order of 3 mg kg-1 at two sites, and 11 mg kg-1 at the third side.
