A sporting site in Melbourne is being used for a weed-tackling treatment that doesn't contain herbicides. A group of green thumbs have used steam to kill weeds, instead of applying chemicals. The Weed Network's Dr. David Low said they were trialling the method at Bayside Council sites. He said they had been researching chemical-free methods for working with weeds for five years. “We have been working with Bayside Council to introduce steam weeding as an alternative to herbicide in sensitive sites used heavily by children, for example for...
Some tips on grazing for invasive plant control
Using livestock for controlling invasive plants has a lot of appeal; the animals seem like a natural, green method; they're cute; and at times they can be a very inexpensive way to do some weed control. But there are also various difficulties and issues with using livestock that should be understood before you jump into a grazing program, I've discussed some below.
Livestock have different eating preferences and needs; Cattle (photo of cattle courtesy of Jack Kelly Clark, UCANR) like grass, sheep like grass and forbs, goats like browse (foliage on stems of woody shrubs, young stems and bark, like photo), and horses like grass.
While conducting a field experiment testing herbicides for control of sahara mustard in Borrego Springs in 2011, out of a corner of my eye I saw a ring of rusty brown around an ant hole.
Being curious I looked closer. It was an organized mound that was maybe 1 inch high and 3 inches across of redstem filaree (Erodium cicutarium) fruit. It was exclusively filaree, nothing else.
So I explored a little more on my knees and saw these small black ants a foot or so away on a well-beaten trail. Most of the ants had a filaree fruit in its mouth. I don't know the species of ant, but a quick Google search suggests that it is a species of...

Abstract: Reduction in herbicide use in non-agricultural areas is being imposed by a growing number of governments, triggering the development of alternative strategies for weed prevention and control. This study aimed to determine the weed preventive abilities of different paving types, the required treatment frequency of non-chemical weed control scenarios on these pavements and the associated weed species composition. A test parking area, constructed with four concrete paving types, was sown with a mixture of dominant weed species. Six scenarios with repeated use of a single weed control method (brushing with waste removal, hot air, selective application of hot water and three scenarios with flaming) and two...
