The efficacy of selected biological and chemical control agents against Heterobasidion abietinum on Abies cilicica

摘要: Summary The efficacy of 30% aqueous urea solution, borax powder and spore suspensions Phlebiopsis gigantea Trichoderma harzianum against establishment artificially inoculated Heterobasidion abietinum on Abies cilicica was tested both in the field a simulated stump treatment experiment carried out growth chamber. In field, each four selected stands 20 fresh stumps per control agent were treated left as untreated controls. two stands, treatments applied June others November. Stumps sampled twice, at 6- 12-months after treatment. chamber, 10 log pieces used, sampling performed 6-week incubation. Results consistent between experiments; mean efficacies 98.8 99.4% 80.2–91.3 89.4–90.1% samplings experiment, respectively. Despite high P. gigantea (85.9%) T. harzianum (97.5%) these biological agents 47.1–49.2 61.3–65.5%,
