Chickpea plays an important role in the drive to develop rotation crops for sustainable northern farming systems. However, weeds and a limited herbicide response arsenal have been barriers to wider adoption of chickpea. In the northern grains region, the GRDC-supported project to develop integrated weed management systems has started developing effective herbicide strategies for the worst weeds.
Growers nominated turnip weed as the most troublesome for early post-emergence control, followed by sow thistle, black bindweed and wireweed, variegated thistle and prickly lettuce. Turnip weed also topped the list of late postemergence weed problems.
Research is now focusing on trial treatments with a variety of herbicides, in addition to the commonly used Tough, for early post-emergence and a non-selective crop-topping strategy after flowering.
