Fifth-Year Pine Growth Response To Woody Release Treatments In Young Loblolly Plantations, Andrew W. Ezell, Jimmie L. Yeiser, L. R. Nelson Jan 2013

Fifth-Year Pine Growth Response To Woody Release Treatments In Young Loblolly Plantations, Andrew W. Ezell, Jimmie L. Yeiser, L. R. Nelson

Across the South, many forest land managers may opt to use mechanical site preparation, especially when soil treatments are deemed appropriate. While these mechanical treatments may be highly effective at addressing a particular soil problem or debris issue, they are typically less effective at control of competing vegetation. In these scenarios where pines are planted, a woody release treatment using herbicides is usually applied at the end of either the first or second growing season. The purpose of these applications is to provide long-term control of the woody competitors with typically short-term control of any herbaceous species on the site.


Use Of Aminocyclopyrachlor For Forestry Site Preparation In The Southeastern U.S., Andrew W. Ezell, Ronnie Turner, Jimmie L. Yeiser Jan 2012

Use Of Aminocyclopyrachlor For Forestry Site Preparation In The Southeastern U.S., Andrew W. Ezell, Ronnie Turner, Jimmie L. Yeiser

Faculty Publications

It is not often that new chemistry is made available for use in forestry applications. Aminocyclopyrachlor is a new active ingredient which may have usefulness as a forestry herbicide. Research using this active ingredient began in 2005 and is continuing in university projects across the South. Both hardwood control efficacy and pine tolerance have been evaluated in these trials. A total of 60 different treatments have been evaluated for use in site preparation applications in Mississippi and Texas. This herbicide is effective on a number of species including some invasive exotics. It will probably not be a stand alone treatment, …


Split-Season Herbaceous Weed Control For Full-Season Seedling Performance, Jimmie L. Yeiser, Andrew W. Ezell Jan 2010

Split-Season Herbaceous Weed Control For Full-Season Seedling Performance, Jimmie L. Yeiser, Andrew W. Ezell

Faculty Publications

Results from four loblolly pine (Pinus taeda L.) sites, one in each of MS and TX in 2001 and again in 2002, are presented. Twelve herbicide treatments and an untreated check were tested. Herbicide treatments were applied early (mid- March), late (mid-May), both timings, or not at all to achieve, early- late-, full-season, or no weed control. When averaged across all four sites and compared to the early treatment, bare ground was less from April through July and April through November on late treated and untreated plots, respectively. Full-season weed control provided numerically more bare ground than other treatments. When …


Establishment And Growth Of Cherrybark Oak Seedlings Underplanted Beneath A Partial Overstory In A Minor Bottom Of Southwestern Arkansas: First Year Results, Emile S. Gardiner Jan 1999

Establishment And Growth Of Cherrybark Oak Seedlings Underplanted Beneath A Partial Overstory In A Minor Bottom Of Southwestern Arkansas: First Year Results, Emile S. Gardiner

Faculty Publications

-Advance regeneration is frequently inadequate to sufficiently restock the oak component of many bottomland stands, especially on productive sites with high levels of competition. We initiated a study near Beirne, AR to examine the effects of pre-plant control of Japanese honeysuckle Thunberg) and seedling quality on establishment success and vigor of oak reproduction beneath a partial canopy. Nine, 2-acre plots were delineated in the stand that was harvested a residual stocking level of 30 percent in the fall of 1996. Honeysuckle pre-plant control treatments randomly applied to the nine were an Escort application in the spring of 1997, an Escort …


Herbicide And Fertilizer Combinations For Newly Planted Loblolly Pine Seedlings On A Flatwoods Site In Southeastern Arkansas: Year Three Results, Jimmie L. Yeiser Jan 1999

Herbicide And Fertilizer Combinations For Newly Planted Loblolly Pine Seedlings On A Flatwoods Site In Southeastern Arkansas: Year Three Results, Jimmie L. Yeiser

Faculty Publications

Herbicide and fertilizer combinations were tested for enhanced loblolly pine (Pinus taeda L.) seedling performance on a chemically prepared, flatwoods site in southeastern AR. Fertilizer treatments were selected combinations of 40,50, and 50 pounds per acre of elemental N, P, or K, respectively. Arsenal+Oust (4 ounces+2 ounces per treated acre) was applied for herbaceous weed control (HWC). One treatment of herbicide or herbicide+ fertilizer was applied per year; the same rate was used for years one (1996) and two (1997). After three growing seasons, the greatest seedling volume resulted from two treatments of HWC+NPK fertilizer. Two treatments of HWC alone …
