THE RESPONSE OF NATIVE HAWAIIAN GRASSES TO SEQUENTIAL APPLICATION OF PRE AND POSTEMERGENCE HERBICIDES.

Two experiments: One to determine the response of emoloa and pili grass to 4 preemergence herbicides applied twice to transplants and the other to determine the response of both grasses to two postemergence herbicides alone and in combination.

PRE-AND POSTEMERGENT HERBICIDES ON 2 AND 4 WEEK OLD EMOLOA (ERAGROSTIS VARIABILIS) SEEDLINGS GROWN IN GREENHOUSE TRAYS OUTDOORS.

Outdoor tray study to determine the response of 2 and 4 week old seedlings of emoloa to spray applications of both pre and postemergence herbicides.

EVALUATION OF HERBICIDE SPRAY APPLICATIONS TO SEEDLING EMOLOA

Direct seeded field grown emoloa seedlings are treated with both pre and postemergence herbicides applied with a 20 foot tractor mounted sprayer. Seedlings are 14 and 42 days old when treated. Treatments are similar to those found in tray study, see above.
