||Feeding larvae cause drying up of central leaf and dead heart symptoms in 1-4 weeks seedlings
||Timely planting, use of high seed rates Chemical control using thionex, carbaryl etc).
Found on the under side of leaves and funnel.
Secret honeydew that leads to sooty molds growth.
||Chemically using malathion, dimethoate (rogor), diazinon
||Suck sap from leaves to cause stunting. Mainly prevalent during hot dry spells
||Spaying with acaricides
||Penetrate stem through funnel at any stage of growth
||Use chemicals like endosulfan, carbaryl, thionex, carbofuran
||Adults suck sup from the developing grain
||Control chemically using dimethoate
||These feed on the sorghum head thereby reducing grain yield
||Control biologically by scouting and hand picking but chemical control may be used.
||Remove sown seeds or seed from panicle. Less damage when crop mature at same time or on extensive sorghum fields
||Scaring is the answer to the problem
||Irregular molted pattern within internodes especially on peduncle.
||Control (rotations, clean cultivation, destroy residues
||Infected seedlings are chlorotic, stunted and may die pre maturely.
||Treat seed metaloxyl, deep ploughing, use resistant varieties
||Molds develop on grain on the panicle especially when crop matures during periods of high rainfall and humidity
||Control by adjusting sowing dates.
||Infection is from panicle emergence through fertilization may cause complete crop loss
||Use of resistant varieties, proper rotations, destroy residues
||Ear head become swollen and turn gray
||Spray with fungicides, use of resistant varieties, removing smutted heads
