The crop wheel turns again, for weed control

Reducing crop area by about 6 per cent and increasing livestock numbers are expected to become the trend in WA's northern agricultural area in the next five years. These findings, from a survey of growers, focus on herbicide-resistant weeds and integrated weed management. Increasing stock numbers in pasture phases is a potential strategy to tackle herbicide-resistant weeds. The survey also showed that high cereal crop seeding rates was the most widely adopted integrated weed management practice. Whole-farm economic modelling suggested it was important to maintain wheat area at or above 40 per cent of arable land, to maintain farm profitability for northern wheat belt growers. Therefore, wheat area must be maintained as the total area of crop is reduced.
