Experiments on direct isolation of Pythium spp. from Finnish sugar beet soils

Antagonistic Activities of Trichoderma spp. on Phytophthora Root Rot of Sugar Beet

Trichoderma species are among important antagonists of plant pathogenic fungi. The main purpose of this study was to evaluate the biocontrol potential of native Trichoderma spp. isolates from sugar beet fields against Phytophthora drechsleri and P. cryptogea, the causal agents of Phytophthora root rot of sugar beet. During 2007–08, 85 isolates of Trichoderma spp. from sugar beet fields in eight...

Biosurfactant production in sugar beet molasses by some Pseudomonas spp.

In this study rhamnolipid biosurfactant production was investigated in eighteen strains of Pseudomonas spp.. Rhamnolipid by these strains was determined by a spectrophotometric method in nutrient broth medium (NB). From the 18 strains screened, two Pseudomonas strains (Pseudomonas luteola B17 and Pseudomonas putida B12) which had produced the highest percentage yield of rhamnolipid were examine...

The Effect of Soil Acidity on Sugar Beet Growth Some Natal Soils

During the latter part of 1975 an investigation was conducted in the Natal Midlands to locate sites, representative of the main bioclimatic subregions, that would be suitable for sugar beet experiments. Soil acidity was identified as an important limiting factor in the majority of soils examined. A glasshouse study with sugar beet revealed a marked response to lime where soil pH values were les...
