Brad Jones, of Tammin, is part of a GRDC Kwinana East Regional Cropping Solutions Network project investigating key drivers of top-performing farm businesses in WA's eastern wheatbelt... "Using liquid products, we can sow up to 600ha of crop per day, which is about 100ha/day faster than we could achieve with granular fertiliser and has cut our total seeding time to about 15 days if the weather is good," he says... Brad says a range of broad-scale herbicides are used in the fallow to remove herbicide-resistant weeds to make way for dry sowing when the paddock returns to production, typically in a rotation of fallow/cereal/cereal/canola and hay/legumes...

Brome grass needs multi-pronged attack.. When herbicides are put under pressure resistant weeds are quickly selected for, such as this population of brome grass... Break crops need to be employed with other management tools including: high seeding rates at sowing for improved competition with brome grass plants; effective herbicide choice with correct rates, droplet size and timing; regular resistance testing if herbicide failure is suspected; retaining or sourcing clean seed for future use; and monitoring brome grass levels in all paddocks while planning future use...
