Resistance of sorghum hybrids to ergot caused by Claviceps africana
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: N.W. McLaren --- , Republic of South AfricaThirty-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... -
Efficacy of fungicides in the control of ergot (Claviceps africana) in sorghum (Sorghum bicolor) hybrid seed production
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: N.W. McLaren --- ,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,... -
Relationship between ergot and grain mould development in sorghum (Sorghum bicolor (L.) Moench)
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: G. Tarekegn --- Centre for Plant Health Management, Department of Plant Sciences, South Africa N.W. McLaren --- Centre for Plant Health Management, Department of Plant Sciences, South Africa W.J. Swart --- Centre for Plant Health Management, Department of Plant Sciences, South AfricaA 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...
