Agronomic factors affect powdery scab of potato and amounts of Spongospora subterranea DNA in soil
(Springer on behalf of the Australasian Plant Pathology Society, 2014-11)
Severe powdery scab (caused by Spongospora subterranea) occurred in potato tubers harvested from a field trial, which measured effects of agronomic treatments (nitrogen fertiliser rates, irrigation intensities, previous ...
Single nucleotide polymorphism analysis using KASP assay reveals genetic variability in Rotylenchulus reniformis
(American Phytopathological Society, 2019-08)
This study employed single nucleotide polymorphisms (SNPs) to determine the genetic variability present in 26 isolates of Rotylenchulus reniformis from Louisiana, Mississippi, Arkansas, South Carolina, Georgia, Hawaii, and ...
Genetic and virulence diversity, and mating type distribution of Togninia minima causing grapevine trunk diseases in Spain
Fifty eight single-spore Togninia minima (anamorph Phaeoacremonium aleophilum) isolates were recovered from grape rootstock wood of plants that showed symptoms of Petri disease and esca from 2001 to 2008 in Spain. These ...
The density-dependent effect of initial nematode population levels on the efficacy of Trichoderma as a bio-nematicide against Meloidogyne hapla on tomato
(Springer Netherlands on behalf of the Australasian Plant Pathology Society, 2016-10)
Trichoderma strains were tested for their ability to reduce the severity of root-knot nematode (RKN), Meloidogyne hapla galling on tomato roots. In initial glasshouse trials, under low levels of RKN infestation (1.1 eggs ...
