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. 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.

No. 099 Loblolly Pine Release Study Report No. 24; by T. A. Dierauf

November 3, 2020 - Report summarizes findings from plots comparing release from hardwood competition by aerial application of herbicides at age three to no treatment and measured through age 20. Herbicide plots averaged 11% more basal area and 18% more volume than check plots.

No. 100 Loblolly Pine Release Study Report No. 25; by T. A. Dierauf

November 3, 2020 - Report summarizes findings from plots comparing release from hardwood competition by aerial application of herbicides at age two to no treatment and measured through age 18. Herbicide plots averaged 169% more basal area and 215% more volume than check plots.

No. 084 Loblolly Pine Release Study Report No. 13; 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 17. Herbicide plots averaged 68-70% more basal area and 91-99% more volume than check plots.

No. 085 Loblolly Pine Release Study Report No. 14; by T. A. Dierauf

November 3, 2020 - Report summarizes findings from plots comparing release from hardwood competition by aerial application of herbicides at age four to no treatment and measured through age 16. Herbicide plots averaged 22% more basal area and 35% more volume than check plots.

No. 086 Loblolly Pine Release Study Report No. 15; by T. A. Dierauf

November 3, 2020 - Report summarizes findings from plots comparing release from hardwood competition by aerial application of herbicides at age four to no treatment and measured through age 19. Herbicide plots averaged 31% more basal area and 53% more volume than check plots.

No. 087 Loblolly Pine Release Study Report No. 16; by T. A. Dierauf

November 3, 2020 - Report summarizes findings from plots comparing release from hardwood competition by aerial application of herbicides at age three to no treatment and measured through age 15. Herbicide plots averaged slightly less basal area and only 0.4 cords per acre more volume than check plots.
