Effect of Sowing Date on Anthracnose of Sorghum in the Nigerian Sudan Savanna

Summary:The effect of different sowing dates on anthracnose using ICSV 247, a midge resistant cultivar was investigated under field conditions in 1995 and 1996 at Bagauda, Nigeria. Early planting in June and July had higher disease i.e. foliar and panicle anthracnose incidence than the late July and August sowings. Although there was a significant correlation between higher relative humidity for the early sowings and disease severity, the June and early July sowings gave higher yields (although with high mould severity) than later sowing dates. Results indicate that the use of sowing date as a measure for control of anthracnose on sorghum will only be meaningful when farmers integrate it with other control measures including the use of resistant varieties. Based on this data, the need for careful adoption of ICSV 247 in highly midge infested areas of the Sudan savanna is highlighted.
