Seed dressings to combat soil insects are now commonly available and may be the most effective control as well as the least disruptive to natural enemies... Natural enemies of helicoverpa include predators of eggs, larvae and pupae, parasites of eggs and larvae and caterpillar diseases... Control may be more difficult in high-yielding thick canopy crops, particularly when larvae are resting under leaf litter at the base of plants...

Growers now have help in assessing the economics of insecticide spraying to control sorghum midge, a major sorghum pest, thanks to a new online spray calculator... Levels of resistance to the pest vary between hybrids and growers may still need to apply insecticide to protect crops... Growers sowing sorghum later in the season - or after neighbouring sorghum fields have flowered - can expect high midge pressure and lower yields...
