Abstract
Ten different herbicide combinations including Forestry Garlon® 4, Garlon® 4 Ultra, Forestry Garlon® XRT, Chopper®, and Milestone® VM were tested for gallberry (
Ilex glabra) control. Treatments were applied to the understory of a 9-year-old slash pine (
Pinus elliottii Engelm.) plantation in South Georgia. Herbicide tank mixture treatments were broadcast foliar applied at a total delivery volume of 20 GPA and replicated three times in a randomized complete block design. One and two years after treatment plots were evaluated and treatments ranked based on level of gallberry control. Forestry Garlon® 4 performed similar to the new formulations, Garlon® 4 Ultra and Forestry Garlon® XRT. The most effective herbicide treatments for gallberry were achieved with 4 quarts/acre of Forestry Garlon® 4 or 3 quarts/acre of Forestry Garlon® 4 (or Garlon® 4 Ultra or Forestry Garlon® XRT) tank-mixed with 16 oz/acre of Arsenal®.
