Brunfelsia - neurotoxin
Roberta Bagshaw wrote:
I read today in a veterinary publication that Brunfelsia australis contains a potent neurotoxin in the leaves and flowers and is palatable to dogs. The vet who wrote the article was seeing a lot of cases over East, mainly because someone was handing out lots of cuttings to people who stopped to admire his lovely bush! Hmm, interesting, Roberta. Thanks, I'm going to look more into that. L. |

The vet who wrote the article was seeing a lot of cases over East, mainly because someone was handing out lots of cuttings to people who stopped to admire his lovely bush! Hi again, Roberta. I just typed 'Brunfelsia australis' into Google images ( http://images.google.com/images?q=Br... tart=20&sa=N ) and yes, that's a pretty mauve flower so I can see why some people have adopted it as an ornamental plant. I'll be sure to warn anyone I see with it about its toxic properties for dogs. Fortunately we don't have any of that growing wild where we are. Then I decided to look at pics of Cape Weed. Someone in here mentioned it as the old wives tale plant we used to call "wet-the-bed" and yeah, that's wet-the-bed alright. BUT... that's not the weed I've been calling Cape Weed (which is the name the neigbours told me it was.) It's not! The weed that is our particular problem comes up with a pretty little pale butter coloured flower that attracts tons of those similar coloured butterflies. I'll search for weed images and see if I can find the name of it. L. |

Damn, I found a great website that you can click on your zone with many pics of weeds known to that area ( www.weeds.org.au ) but still I can't identify the weed I thought was Cape. Grrr. The closest I can see to resemble it is something like Saggitaria or Parthenium but it's not those. I would take a photo but there's none "up" at the moment coz we've mowed all the tops off. I'll keep searching. L. |

Cape Weed - control the old fashioned way?
Hi Linda
Check out this site - maybe you can identify your weed http://www.directpestcontrol.com.au/weeds.htm Your post reminded me of a conversation that I had recently with my elderly neighbour Val who is a very keen gardener, and keeps a meticulous buffalo grass lawn. The last couple of years we have had problems with clover weed in garden beds and in lawns. The type of clover is that red stemmed one that has a very dense cover - almost a mat - of leaves. Val remembered that years ago (pre-herbicide days) the easy way to rid yourself of many weeds was to apply a strong dose of Sulphate of Ammonia which literally burned the weed by an overapplication of nitrogen. She applied it to her plague of clover and got rid of it! It is certainly a cheap (and relatively safe) solution. Maybe you could try it on a bit of your weed and see what happens?

(Sorry, I know I seem to be vague about availability of these chemicals - but yeah, I am, I'm as vague as... as that stuff you buy from that whatsitsname place, you know?) L. |

It is certainly a cheap (and relatively safe) solution. It works on clover because clover is a nitrogen-fixing plant -- you are giving it a nitrogen overdose, against which it has no defences (you can kill some Australian plants with phosphorus the same way). If Cape Weed isn't a legume, it won't work. You could try boiling water, but as it's a perennial it probably will still stagger along. Okay, that's worth a bash, Roberta. So, Sulphate of Ammonia; where do you buy that?

Sulphate of Ammonia is a good product to use BUT it can't solve this particular problem. Cape Weed is one weed that it will not work on although it will work on other broadleaf plants such as plantain and dandelion and also it can't be used at this time of year. It must be used in Spring (as do most of the other products) which must be used on actively growing weeds. |

OTOH, you can mash the ******* with anything you like and it comes back. It was the pox in swmbo's dowry and I'm not allowed to eradicate it. |
