Description

Aim

To investigate the effect of on-row and inter-row physical and chemical weed control options on wild radish (weed population and crop damage) and performance of a lupin crop sown in wide rows at Ballidu.

Background

Wild radish has developed resistance to most of the herbicide groups (including glyphosate) that are used in Western Australia (WA). Integrated weed management (IWM) strategies employing both chemical and non-chemical weed control options need to be incorporated into lupin production systems to minimise the impact of herbicide resistance within the WA Wheatbelt. IWM tactics are aimed at effectively stopping weed seed set (as much as 100%) by applying double-knock techniques (non-selective chemical and physical weed control), cultural methods, rotation of crop species, rotation of herbicide modes of action, and physical weed control options. Recent work on physical and chemical weed control options in wide row lupins (Riethmuller et al., 2014; Hashem et al., 2010) concluded that inter-row cultivation or shielded spraying (if on-label) can be used in wide row crops in order to reduce weed growth between crop rows while causing minimal damage to the crop plants. The authors also suggested that shielded spraying may be worth further investigation as it did reduce weed seed numbers without a significant yield penalty in that research.
