Key Points Research into biological control of the costly root-lesion nematode could boost yields and reduce losses... The GRDC-funded research is exploring the potential of naturally-occurring soil organisms to suppress RLN... Dr Seymour says the research will result in the identification of the key organisms involved in the suppression of RLN in northern grain-growing soils and an understanding of soil chemical, physical and biological characteristics associated with suppressiveness...

Following mid-season drying-off of vegetation and/or exhaustion of food sources in pastures, dispersal of grasshoppers may result in invasion and severe defoliation of pasture legumes, fodder crops (particularly lucerne), horticultural crops, trees and gardens... Cultural control: Cultural control is difficult on pastures, but maintaining a dense, grassy pasture without bare areas where grasshoppers can lay eggs can help to keep numbers in check...

Tytthus are well known as predators of leaf and plant-hoppers throughout the world... In Australia, the related species Tytthus mundulus is an important predator on the eggs of the sugar cane leafhopper and the introduction of this predator into Hawaii is one of the outstanding successes in biological control... The adult black-headed mirid has an elongate body shape and is about 3 mm long with a dark black head and pronotum (the area behind the head)...

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...
