Integrating Chemical and Biological Control of the Hemlock Woolly Adelgid: a Resource Manager's Guide

Integrating Chemical and Biological Control of the Hemlock Woolly Adelgid: a Resource Manager’s Guide

January 9, 2023 - A non-native invasive insect, the hemlock woolly adelgid (HWA), threatens the ability of natural resource managers to maintain eastern and Carolina hemlocks as critical components of unique forest ecosystems in eastern North America. Although substantial progress has been made in both chemical and biological control of HWA, neither of these tactics applied alone are expected to provide adequate control of HWA throughout its introduced range. This guide presents a methodological... Read More

No. 148 Ten-Year Growth of Loblolly Pine Planted in Different Configurations Targeting Varied Product Objectives

No. 148 Ten-Year Growth of Loblolly Pine Planted in Different Configurations Targeting Varied Product Objectives

November 3, 2022 - Report provides results from a study comparing the growth and productivity of loblolly pine planted at varying densities in four planting configurations. Changing the planting density and between- or within-row spacing met different product objectives while producing up to 51% more volume within a 10-year time frame compared to a 10 ft. x 10 ft. spacing (436 trees per acre).

No. 147 Establishment Methods for Longleaf Pine

No. 147 Establishment Methods for Longleaf Pine

November 3, 2022 - Report provides results from a study of the effects of seedling source (NC orchard mix, GA mountain and GA coastal), competition control methods and planting depth on the establishment and early growth of longleaf pine on an old-field site. Five-year results show that the most important factor in  establishment success was scalping. Shallow planting and Oustar at 8 -12 oz./acre were also helpful. 

No. 146 Establishment Methods for Shortleaf Pine

No. 146 Establishment Methods for Shortleaf Pine

November 3, 2022 - Report provides results from three locations of a study of competition control and fertilizer treatments for establishing shortleaf pine on old-field and cutover sites. Herbaceous weed control (using herbicides or mechanical scalping) at the beginning of the first growing season improved survival and growth of planted shortleaf pine on both old field and cutover sites after two years.

No. 145 Triclopyr Ester for Controlling Tree-of-Heaven

No. 145 Triclopyr Ester for Controlling Tree-of-Heaven

September 14, 2022 - Report provides results from a series of four studies of tree-of-heaven control using triclopyr ester applied at different times during the year by basal spray or cut stump application methods. A mixture of 25% triclopyr ester herbicide in an oil-based carrier achieved excellent tree-of-heaven control for trees up to 16 inches in diameter.

No. 144 Effects of Hardwood Control Timing on Loblolly Pine Growth - Age Five Results

No. 144 Effects of Hardwood Control Timing on Loblolly Pine Growth – Age Five Results

September 14, 2022 - Report provides results from a study of the effects on loblolly pine growth of five hardwood competition control strategies (pre-plant site prep, year-one release, year-two release, one-year layout followed by pre-plant site prep, and no control). After five years, all treatments had effectively controlled hardwood competition and differences in pine growth were directly related to the timing of hardwood control.
