  1. Resistance of sorghum hybrids to ergot caused by <em>Claviceps africana</em>

    Resistance of sorghum hybrids to ergot caused by <em>Claviceps africana</em>

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Thirty-one sorghum hybrids were evaluated for ergot ‘escape’ resistance at Bethlehem and Potcherstroom during the 1996/97 and 1997/98 seasons. Trials were designed so that flowering and artificial inoculation occurred over a range of flowering dates and thus, ergot potentials Non-linear...
  2. Efficacy of fungicides in the control of ergot (<em>Claviceps africana</em>) in sorghum <em>(Sorghum bicolor</em>) hybrid seed production

    Efficacy of fungicides in the control of ergot (<em>Claviceps africana</em>) in sorghum <em>(Sorghum bicolor</em>) hybrid seed production

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Ergot is a disease of unfertilized sorghum ovaries. It is particularly prevalent in seed production where losses may average 10–20% per annum. Protection of the ovary during the critical period of flower opening to fertilization could reduce losses and increase,...
  3. Relationship between ergot and grain mould development in sorghum (<em>Sorghum bicolor</em> (L.) Moench)

    Relationship between ergot and grain mould development in sorghum (<em>Sorghum bicolor</em> (L.) Moench)

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    A greenhouse experiment was conducted to determine the influence of sorghum ergot on the incidence of grain mould pathogens and on damage to sorghum grains. Grain mould pathogens used were Curvularia lunata, Fusarium subglutinans and Phoma sorghina. Inoculation with the...
