The effect of fungal inoculum properties on colonization of nonsterile soil by three isolates of the white-rot fungus Trametes versicolor was investigated. Fungal inoculum properties were examined in separate experiments and were fungal inoculum composition, age of fungal inoculum, concentration of the inoculum and inoculation method. The fungal inoculum(More)
The impact of conventional agrichemicals commonly used in New Zealand apple production on non-target, culturable phyllosphere microbial populations was studied in the laboratory (agar, leaf, and seedling assays) and field (apple orchard). Morphologically distinct bacteria (three), yeasts (five), and filamentous microfungi (two) were used as indicator(More)
Four methods were evaluated over 3 years for their ability to determine the resistance often cultivars of apricot (Prunus armeniaca) to the brown rot pathogens, Monilinia fructicola and M. laxa. Methods assessed were lesion development on wounded and non-wounded inoculated fruit, spore productions from these lesions, the postharvest development of brown rot(More)
A bioassay was developed, using Fusarium seedling blight as a model system, to screen and select for disease suppressiveness in composted and uncomposted radiata pine bark. Four out of the 16 substrates suppressed disease symptoms when oat seedlings were inoculated with 104 conidia/mL of Fusarium culmorum. When three of these composts and the uncomposted(More)
In New Zealand summer rots caused by Colletotrichum acutatum Simmonds (bitter rot) result in significant loss. This pathogen is currently controlled by fungicide sprays. This project was initiated to investigate if populations of naturally occurring yeast biological control agents could be enhanced by application of benign compounds in the field as an(More)
Botrytis cinerea is a major disease of blackcurrants causing premature flower and fruit drop in New Zealand. Because of the risk of fungicide residue from conventional methods, there is a need for the development of non-chemical control strategies as part of a sustainable disease control programme. Potential sources of Botrytis cinerea inoculum for(More)
