No. 097 Loblolly Pine Release Study Report No. 22; by T. A. Dierauf

November 3, 2020 - Report summarizes findings from plots comparing release from hardwood competition by 1) hand chopping, 2) basal spraying herbicides, or 3) mist blowing herbicides at age three to no treatment and measured through age 20. Herbicide plots averaged 6-12% more basal area and 9-13% more volume than check plots.

No. 113 Controlling Herbaceous Competition and Tip Moth – Effects After 16 Years; by T. A. Dierauf and J. A. Scrivani

November 3, 2020 - Report describes the effects of four treatments – herbaceous vegetation control, tip moth control, herbaceous vegetation and tip moth control combined, and no treatment – on loblolly pine growth through age 16. Herbaceous control increased height by 2 feet, diameter by 0.5 inches, and basal area by 25 square feet. Tip moth control had only slight effects on those attributes.

No. 098 Loblolly Pine Release Study Report No. 23; by T. A. Dierauf

November 3, 2020 - Report summarizes findings from plots comparing release from hardwood competition by basal spraying herbicides at two dilution rates at age one to no treatment and measured through age 19. Cordwood yield response varied from +22% on the lower dilution rate to -17% with the higher dilution.
