Controlling arum lily with DPIRD's John Moore

Key takeaways: 1. Not all bulbs can be killed using the same herbicide - some are very specific. Glyphosate is not effective at killing arum lily and will cause more off target damage. 2. Chlorsulfuron is the best choice for arum lily control; has low toxicity and is safer on the bush. 3. Arum lily seeds are spread by fruit eating birds, emus and foxes. The seed passes through birds very quickly. Thankfully the seed does not have long-lived dormancy in the soil and is only viable for up to 12 months. Stop seed set and you can stop movement. 4. Avoid spraying when there is moisture around - always aim to spray dry leaves. 5. Under a thick stand of arum lily there can be over 100 tonnes of root material/ hectare. The goal is to spray maximum leaf area, to get maximum chemical into the plant and kill the maximum amount of root material.
