Abstract

Container-grown shortleaf pine (Pinus echinata Mill.) seedlings inoculated with Pisolithus tinctorius and drenched with benomyl formed more mycorrhizal roots than undrenched seedlings. Seedlings were drenched (2.5, 5, and 10 mg ai in 15 ml of water per individual) prior to sowing and at either 2-, 4-, or 8-week intervals. Pisolithus formed best at the highest benomyl level, 10 mg every 2 weeks. Benomyl application increased seedling diameter, height, and weight. Highest benomyl dosages produced the largest seedlings.
