  1. Host-specificity testing of <em>Puccinia xanthii</em> var. <em>parthenii-hysterophorae</em>, a potential biocontrol agent for <em>Parthenium hysterophorus</em> in South Africa

    Host-specificity testing of <em>Puccinia xanthii</em> var. <em>parthenii-hysterophorae</em>, a potential biocontrol agent for <em>Parthenium hysterophorus</em> in South Africa

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Following its introduction into Australia, the rust fungus Puccinia xanthii var. parthenii-hysterophorae has played an important role in the integrated approach to manage Parthenium hysterophorus. The rust was imported from Australia and established within quarantine facilities in South Africa. Supplementary...
  2. Influence of temperature, aluminium chloride toxicity and exposure to <em>Bacillus subtilis</em> on the germination of okra

    Influence of temperature, aluminium chloride toxicity and exposure to <em>Bacillus subtilis</em> on the germination of okra

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Influences of heat, aluminium chloride concentration and exposure to Bacillus subtilis on germination of okra seed were investigated. A factorial experiment was conducted using Petri dish assays, and seed germination percentage and coleoptile length were recorded for the different treatments...
  3. The potential of omics technologies as tools to understand the environmental factors influencing okra (<em>Abelmoschus esculentus</em>) growth and adaptation

    The potential of omics technologies as tools to understand the environmental factors influencing okra (<em>Abelmoschus esculentus</em>) growth and adaptation

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Leading crops such as cotton, maize, rice and wheat were the first to be studied using omics technologies (genomics, transcriptomics, proteomics and metabolomics). Those crops that are considered less significant, such as okra (Abelmoschus esculentus (L.) Moench), are yet to...
  4. Reaction of South African spring wheat cultivars to head blight caused by <em>Fusarium graminearum</em>

    Reaction of South African spring wheat cultivars to head blight caused by <em>Fusarium graminearum</em>

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Head blight caused by Fusarium graminearum (Schwabe) is an important wheat (Triticum aestivum L.) disease in the centrepivot irrigation areas of South Africa. Fifteen cultivars, Gamtoos, Inia, Kariega, Marico, Nantes, Palmiet, SST 38, SST 55, SST 57, SST 65, SST...
  5. Initial studies on fungicide evaluation for efficacy in the management <em>of Fusarium</em> head blight in wheat

    Initial studies on fungicide evaluation for efficacy in the management <em>of Fusarium</em> head blight in wheat

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The efficacy of the fungicides bromuconazole, carbendazim/epoxiconazole, carbendazim/flusilazole, carbendazim, cypro- conazole, flutriafol, prochloraz, propiconazole and tebucona- zole in controlling head blight was determined in the greenhouse. Wheat (Triticum aestivum L.) spikes of cultivar SST 38 were inoculated at the onset...
  6. Fungicide sensitivity in <em>Tapesia yallundae</em> populations collected from 15 wheat fields in the Western Cape province of South Africa

    Fungicide sensitivity in <em>Tapesia yallundae</em> populations collected from 15 wheat fields in the Western Cape province of South Africa

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    In the Western Cape province of South Africa, eyespot disease (Tapesia yallundae) of wheat is primarily controlled by fungicide applications. Previous studies have shown, however, that isolates of T. yallundae vary in their response to fungicides. In the present study,...
