Biocontrol of Fusarium circinatum Infection of Young Pinus radiata Trees
Pitch canker, caused by the fungus Fusarium circinatum, is a major disease of Pinus radiata currently controlled to some extent in nurseries by good hygiene and application of synthetic fungicides. The aim of this study was to evaluate alternative strategies to control fungal infections in nurseries and young pine plantations. The antagonistic effects of biocontrol bacteria and essential oils a...
متن کاملSusceptibility of Douglas fir ( Pseudotsuga menziesii ) to pitch canker , caused by Gibberella circinata ( anamorph = Fusarium circinatum )
For better characterization of the risk of pitch canker (caused by Gibberella circinata , anamorph = Fusarium circinatum ) to Douglas fir ( Pseudotsuga menziesii ), Californian isolates, selected exotic isolates, and ascospore progeny of a cross between wild-type Californian isolates were tested for aggressiveness to this host species. In addition, seedlings from representative provenances of P...
متن کاملMolecular mating type assay for Fusarium circinatum.
A rapid and reliable mating type assay for Fusarium circinatum was created by applying primers specific for the MAT1-1 and MAT1-2 mating type alleles to genomic DNA in a single PCR. A similar approach may be applied to fungi not previously shown to reproduce sexually, thus enabling studies of population structure and inheritance.
متن کاملFactors influencing infection of mechanical wounds by Fusarium circinatum on Monterey pines
Pitch canker, caused by the fungus Fusarium circinatum , is a disease affecting many pine tree species. In California, Pinus radiata (Monterey pine) is the principal pine host affected by pitch canker. This investigation into factors affecting infection frequency by F. circinatum of P. radiata examined the influence of: (i) wound size; (ii) relative humidity; (iii) time of inoculation; (iv) ino...
متن کاملDouble-stranded RNA mycovirus from Fusarium graminearum.
Double-stranded RNA (dsRNA) viruses in some fungi are associated with hypovirulence and have been used or proposed as biological control agents. We isolated 7.5-kb dsRNAs from 13 of 286 field strains of Fusarium graminearum isolated from maize in Korea. One of these strains, DK21, was examined in more detail. This strain had pronounced morphological changes, including reduction in mycelial grow...
