NGN - Effective control of three corner jack (spiny emex) species in lentils in the mid and upper north of SA
The control of three corner jack (spiny emex) species in lentils has been raised as a significant constraint on light soils in the western areas of the mid- and upper-north of SA. Generally, due to multiple herbicide options, three corner jack is well controlled in cereals. However, feedback into the National Grower Network in South Australia have reported that controlling three corner jack species in lentils is a significant concern for growers with feedback provided by impacted growers indicating that there is a gap in knowledge for successful management techniques for this weed. It is suspected that there are actually two species occurring in this area, Rumex hypogaeus and Rumex spinosa.
An understanding of the geographic extent of the three corner jack issue, confirmation of the two species, estimated economic and farming systems impacts of this weed and current control tactics and management strategies should be developed. This will set the foundation for local field trials to test promising herbicide options with registered use patterns but also include limited unregistered options after consideration of path to market. The utilisation of local extension platforms should be prioritised to inform the target audience on the best-practice management of this weed.
