My war on weeds over the years, in no order of importance, has been against poa tussock, bracken, blackberry, fireweed, thistle, giant parramatta grass, paddy’s lucerne, tobacco plant and Indian weed.
I have ignored the increasing prevalence of Arum Lilly (Zantedeschia aethiopica) as it is mostly confined to the creek banks and has so far no impact on the pasture.
But it’s time to move on it
This plant is native to South Africa and was brought to Australia as a garden ornamental.
It spreads by plant parts and seed and is toxic to people, livestock, pets and native animals.
Previously I have sprayed with glyphosate on a random basis when targeting other weed species.
The lilly takes a considerable time to die under those circumstances.
Another product I’ve used for bracken and blackberry, Metsulfuron-methyl 600 g/kg (BrushOff®) at a rate of 10 - 20 g per 100 L water plus non ionic surfactant, produces a much quicker result according to reports and that will be my chemical of choice.
Experts say the best time to spray is June to October, especially when the plants are flowering. This is our winter into spring time when the weather is cooler and conducive to outdoor work. Also the snakes are still ‘asleep’, until around late August that is.
