Streszczenie:

Root-knot nematodes (RKN), Meloidogyne spp., are the most economically important genus of plant parasitic nematodes that cause considerable damage and yield losses of horticultural crops worldwide. RKN management strategies tend to reduce chemical nematicides by encouraging alternative control methods like the use of plants bearing resistance genes (R-genes) and/or by microbe-inducing plant resistance, and the antagonistic potential of soils. In the thesis, two biological control approaches of Meloidogyne spp. were evaluated: 1) the application of selected nematode antagonists, the fungus Poch

Néanmoins, les conditions de fonctionnement de ces populations bactériennes dans le sol restent très mal connues. Dans certains sols, dits résistants aux maladies, ces bactéries phytoprotectrices sont présentes à des effectifs importants et leur activité est suffisante pour protéger la plante malgré la présence du pathogène.

Take-all, caused by the soilborne fungus, Gaeumannomyces graminis var. tritici (Ggt), is an important root disease of wheat that can be reduced by take-all decline (TAD) in successive wheat crops, due to general and/or specific suppression. A study of 112 New Zealand wheat soils in 2003 had shown that Ggt DNA concentrations (analysed using real-time PCR) increased with successive years of wheat crops (1-3 y) and generally reflected take-all severity in subsequent crops. However, some wheat soils with high Ggt DNA concentrations had low take-all, suggesting presence of TAD. This study investiga

Leguminous cover crops are promising as Meloidogyne spp. suppressants but where populations of mixed species occur, their potential remains uncertain.

This thesis includes two studies. The first study examined changes in soil characteristics as a result of prolonged conifer dominance in successional aspen-conifer forests. Changing disturbance patterns in aspen-conifer forests appear to be altering successional dynamics that favors conifer expansion in aspen forests. The primary objective of this paper was to identify how increasing conifer dominance that develops in later successional stages alters forest soil characteristics. Soil measurements were collected along a stand composition gradient: aspen dominated, aspen-conifer mix, conifer dom

Streszczenie:

Compost can suppress soilborne plant pathogens that cause significant damage on globally important food crops. However, reports of plant pathogen suppression are inconsistent likely because there are no established standards for feedstock material, application rate, and maturity age upon application. Excellent results can be achieved in greenhouse trials, but field applications are much less reliable. Disease suppression occurs through the activity of biocontrol organisms (direct antagonism), and general microbial competition. Biocontrol species are hypothesized to colonize the pile during the

Soil spectroscopy is a promising technique for soil analysis, and has been successfully utilized in the laboratory. When it comes to space, the presence of vegetation significantly affects the performance of imaging spectroscopy or hyperspectral imaging on the retrieval of topsoil properties. The Forced Invariance Approach has been proven able to effectively suppress the vegetation contribution to the mixed image pixel. It takes advantage of scene statistics and requires no specific a priori knowledge of the referenced spectra. However, the approach is still mainly limited to lithological mapp

Rhizoctonia solani AG8 is a significant soil-borne pathogen of cereal roots in semi-arid Mediterranean regions of Australia and the Pacific North West region in the United States of America, causing severe productivity and economic losses to farmers. During the past twenty years the conversion of many farming systems to conservation tillage has meant that the mycelial network of the pathogen is no longer seasonally disturbed by cultivation which has subsequently increased the potential for greater incidence of Rhizoctonia root rot.
