heavily grazed / defoliated; there are at least 30 desperate kangaroos hanging out around the old farm dam which was a close to empty stinking puddle on Sat 7 Feb. Cut and paint and mapped with Field Maps; I'm not sure whether herbicide treatment of defoliated plant will work and appreciate advice.

Let us know if the herbicide works. Glyphosate works on the roots so needs active sap flow to get it there. You need to poison the cut within 30 seconds so the cells don't seal off, but sap will flow for a while longer if the plant is actively growing (sending sugars from the leaves and nutrients from the roots in a two-way process).

Thanks Mike I know the principle (immediately treat cut surface etc) but I don't know whether the method works with woody weeds that herbivores defoliated. FoMM discontinues treatment of deciduous woody weeds such as Hawthorn and Nettle tree in autumn; we only treat evergreens the whole year round including in winter.
