What weeds affect cotton crop's production in Australia?

Question

What weeds most affect cotton production in Australia?? In particular the Darling Downs QLD. If any one knows of a site then that would be great. I've tried searching for ages and I can't find anything useful. If you can think of any of the weeds names then that would also be very helpful.

Answer 1

The first two links are fact sheets with some key weeds listed for cotton in the Darling Downs (it does say dryland cotton), and the third has info about weed species in cotton.  Good luck, hope it helps a bit.  Another suggestion, maybe you could find a Qld Dept. of Primary Industries office in the Darling Downs region and ask them for help as they might know or know who to ask.

Answer 2

Here is a good site showing the weeds of Australia.  You can narrow it down to your desired region.
