Eight More Weeds Will Bite The Dust

Vigilant direct-application herbicide gel, already popular with both professional and hobby gardeners, now officially has a whole lot of extra clout.

Approval has been granted for it to be used on eight extra weeds. These are plants like beautiful agapanthus, so popular for arid access drives because of its hardiness, that will out-compete natives once they get loose from their garden confines. The other seven that can now be more readily keep under control are gorse, Kahili ginger, Darwin’s barberry, elaeagnus, woolly nightshade, cotoneaster, and wandering Willie (or wandering Jew, depending on where you grew up).

Over eight years of research and testing has gone into this product, which is classified as a non-scheduled hazard – the safest classification.

Being able to apply gel from a brush bottle, with no spray and therefore no spray drift, is a small miracle. Applying gel with a paint roller is now recommended for wandering Willie, which in native bush can form a dense carpet and prevent the regeneration of native plants. Dog owners who curse because wandering Willie can cause itchy eczema in animals will have an added reason to get to work to remove the weed.

“Vigilant only needs one application,” HortResearch’s Brian Ward said. “There is no spray drift so you are just selectively removing the unwanted plants.”

In an ideal world we could have grown what we liked in our gardens, and retained unspoiled forests and beaches to be enjoyed on holidays. But 240 introduced plants have found their way into nooks and crannies where some have become so firmly established that it’s been close to impossible to remove them, and are posing a significant threat to our native species and our biodiversity. Vigilant gel herbicide now offers a low-impact way to remove them.
