The results suggest that A. migulanus Nagano has potential as a biological control agent for use against DNB in forest nurseries. The conidial density and percentage germination of D. septosporum on needles were also greatly reduced on seedlings treated with A. migulanus Nagano compared with the A. migulanus NCTC 7096 and control treatments. In contrast, treatment with A. migulanus Nagano reduced Dothistroma needle blight (DNB) severity to 1.1 ± 0.4%. Disease severity (% needles with conidiomata) on control plants was 5.8 ± 1.7%, compared with 6.2 ± 2.0% on plants treated with A. migulanus NCTC 7096. The results suggest that A. migulanus Nagano has potential as a biological control agent for use against DNB in forest nurseries.ĪB - The ability of two strains of the antibiotic-producing bacillus Aneurinibacillus migulanus to control Dothistroma septosporum infection of pine was tested in artificial inoculation experiments on 2-year-old Pinus contorta plants. This disease first appeared on the upper part of the needles, and the needles then became withered and gradually showed light black spots, although they remained green. mongolica trees in four forest farms, and the infection rate among the forests was 24.58 (n 240). N2 - The ability of two strains of the antibiotic-producing bacillus Aneurinibacillus migulanus to control Dothistroma septosporum infection of pine was tested in artificial inoculation experiments on 2-year-old Pinus contorta plants. From May to September 2020, black spot needle blight was found on hundreds of P. The comments of two anonymous reviewers improved this manuscript. MB, HTD, HZ and FO gratefully acknowledge support via short-term scientific missions in COST Action FP1102 DIAROD. SF received funding from the Scottish Forestry Trust, The Forestry Commission and Forestry Commission Scotland. T1 - Biological control of Dothistroma needle blight on pine with Aneurinibacillus migulanusįA was supported by the Government of Kuwait.
