Dose rates with a * indicates that label rates of chemicals can be used on bare ground applied post seeding and prior to seedling emergence. Alphacypermethrin and Esfenvalerate bare ground treatment should be applied to moist soil.

Dose rates with a + indicates that paddocks with large quantities of stubble or plant residue are likely to have increased numbers of false wireworms and be difficult to control. Chlorpyrifos application techniques (eg. spray, baiting, soil incorporated) vary with individual labels.

Balaustium Mite

No chemicals currently registered. Rates of alphacypermethrin that are used against weevils have been effective on balaustium. Rates of bifenthrin used for bryobia have given poor kill of balaustium.

Blue Oat Mite

Generally a minor pest in Western Australia and mostly controlled with chemical and rates used against redlegged earth mite. Mite samples can be sent to Entomology, Department of Agriculture and Food, Western Australia for free identification.

Slugs and snails

For control of slugs and snails, growers may apply metaldehyde (50 grams per kilogram (g/kg) active ingredient (a.i)) (trade name Metarex). Rain fast baits may give more effective control, or methiocarb (20g/kg a.i) (Trade name Mesurol). Pellets are often used at a rate of 5 kg per hectare (kg/ha) for broadacre and give variable results depending on pest numbers, weather conditions and plant biomass.

Control of cereal seedling pests. Registered chemicals for cereal crops autumn/winter 2014

A synthetic pyrethroid top-up spray is recommended to be applied 7-8 weeks after sowing imidacloprid treated seed for control of aphids vectoring barley yellow dwarf virus (BYDV)
