Maleic Hydrazide Fails to Control Fertilized Bermudegrass

A recent study near Oxford, Miss., used large quantities of commercial fertilizers in an attempt to improve survival and stimulate height growth of loblolly pine (Pinus taeda) seedlings planted on adverse sites. Since excessive weed competition was probable, a growth inhibiter, maleic hydrazide (1, 2-dihydropyridazine-3, 6-dione) was applied to the weeds -- predominantly Bermudagrass (Cynodon dactylon). Maleic hydrazide arrests plant cell division for 4 to 6 weeks, but does not affect cell enlargement. In the presence of the heavy concentrations of commercial fertilizers, however, the maleic hydrazide had no apparent influence on the Bermudagrass, whose growth appeared well in excess of what might be expected from cell enlargement alone.
