Blackberries (Rubus anglocandicans, R. fruticosus, R. laudatus, R. rugosus, and R. ulmifolius)
Blackberry is a perennial and semi-deciduous prickly weed that most of us are familiar with, often forming dense thickets on or near waterways.
Begin control measures only if you have plans to return for at least three years in a row. It is recommended to spray during summer growth, or manually remove anytime during the growing season. Manual control can be achieved on small infestations, especially in natural bushland, and larger infestations along waterways where spraying is not permitted.
Metsulfuron plus Pulse is one of several spraying options. On larger infestations it can be used before the more expensive Grazon that has little effect on grasses. If you are using chemicals, use no more than recommended by the manufacturer (it won’t make it any more effective). Surfactants (like Pulse) are harmful to our frogs. Good rule of thumb is "if you hear croaking don't use surfactants".
Goats have proved effective at control so long as in well secured enclosures.
Rusts have turned up and been experimented with in our region but their usefulness is seemingly dependent on specific seasonal weather conditions being met.
