Effective Herbicide Treatments

To be successful with herbicides require

• the most effective herbicide,

• applied using the correct method, and

• applied during the best time period.

Prescribed Burning and grazing can assist by preparing the site and severing vines for treatingregrowth.

Usually only lower portion of vines must be treated

Recommended control procedures:

Foliar sprays Garlon 3A or Garlon 4 as a 2% solution July to October.Sometimes the air yams take up the herbicide: otherwise, bulbils must be collected anddestroyed to prevent sprouting (do not attemptto compost).

Cut-treat climbing plants just above the soilsurface and immediately treat the freshly cutstem with undiluted Garlon 3A.
