Abstract
Seeds of mould resistant sorghum cultivars IS 8545 and PVK 801, as well as those of the susceptible cultivars Bulk Y, SPV 104 and CSH 9 were used to investigate the nature of the seedborne nature of the predominant mould fungi infecting sorghum. Alongside this, the efficacy of thiram and Bavistin [carbendazim] SD and ST in controlling seed mould fungi was determined. Infection of seed coat, endosperm and embryo of sorghum was due to Fusarium verticillioides and Curvularia lunata [Cochliobolus lunatus]. Infection of plant tissues was lower in resistant than susceptible cultivars. Infection by C. lunata and F. verticillioides ranged from 20 to 84% and from 12 to 74%, respectively. All the fungicide treatments reduced the grain colonization by mould fungi in cultivars Bulk Y, SPV 104, IS 8545 and PKV 801 compared to the control. Seed treatment with thiram reduced seed infection by C. lunata, whereas seed treatment with bavistin reduced seed infection by F. verticillioides. Reduction in grain mould infection resulted in a 4 to 47% increase in grain yield.
