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.
