Broadleaf weed control in chickpeas is particularly challenging due to the lack of available post-emergent herbicides suitable for in-crop application. This issue was raised by growers at an NGN forum in Gindie, Queensland, where there was significant interest in exploring alternative options to the limited chemistry currently used by Central Queensland growers. In Central Queensland, growers face weed burdens in chickpea crops from species such as Mexican poppy, sow thistle, and wild turnip, for which the current standard grower practice of pre-emergent application of isoxaflutole, simazine or terbuthylazine are often ineffective. There is an opportunity to demonstrate the efficacy and suitability of recently registered pre-emergent herbicides within Central Queensland systems. Currently, growers in the region lack knowledge about their use. This investment will evaluate herbicides (pre and post emergent) currently registered for use in chickpea to assess their fit in the region and efficacy against local problematic weeds through replicated small plot field studies, with extension of this information to growers through field walks and presentation of results.
