we have serious problem with this alien invader tree here in South Africa esp. mountain tributiries, its a serious threat to our local vegetation because it has no natural enemies here. What can one do to get rid of it? I'm only interested in poisons that would not be harmful to the environment/ecology.
Do anyone know if there is a registered foliar or cut stump poison to get rid of Pyracantha angustifolia?
Trade name is "Garland," and it is topically applied to the cut stump.
It takes care of everything. I'm not sure what the chemical name is, but you could Google it.
We've also used glyphosate (trade name Roundup) concentrate to paint stums with and it works as well, and is registered for that use.
Both of these are reasonably safe when used as designated, because they break down over time, and are only applied to the stump.
Reply:Try a specific defoliant or biological poison. Approach a toxicologist.
