Herbicide tolerance of Desi chickpea varieties - Merredin locations

To identify herbicide sensitivities of new or potential new chickpea varieties with the view to reduce their yield losses due to herbicide damage.

Key messages

Desi chickpea varieties CBA Captain, Neelam and PBA Striker showed good tolerance to a range of chickpea herbicides or herbicide mixtures at registered rates and timings with good crop safety margin.

IBS application of simazine + Balance® appears safer than PSPE application especially on PBA Striker.

A new herbicide Ultro® 900 WG at 1.1 kg/ha IBS was tolerated well by all the varieties.

Note: Always follow label recommendations. The Department Primary Industries and Regional Development, does not endorse the use of herbicides above the registered rate or off-label use of herbicides or off-label tank mixes. Crop tolerance and yield responses to herbicides are strongly influenced by seasonal conditions.
