Honeydew oozing on a grain sorghum head caused by Claviceps africana (ergot)... Crops at greatest risk are: forage sorghums heads on ratoon crops flowering late in the season tillers on late-flowering plants crops in which pollination has been affected by a cold snap before or at flowering... To minimise the risk of ergot contamination, growers should: sow at recommended times ensure even flowering (use press wheels, high-germination seed, accurate seed depth control; good crop nutrition, wide row spacing (90-100 cm), especially with hybrids that tiller heavily, and consider pre-harvest kill-off of tillers using glyphosate herbicide) graze forage sorghum heavily to delay flowering until after grain sorghum has flowered...
