Feathertop Rhodes grass is a really quickly growing weed.
It will emerge after only two days of moisture and then its growth rate's quite quick.
Quite small, light, fluffy seeds, most of them will land close to the parent plant.
Those seeds do have a dormancy so it's between six and 10 weeks, but after that period of
time, if the temperature's right and if the moisture is right, you can get a large flush
of emergence from those seeds that have been dispersed.
Another characteristic of feathertop Rhodes grass that makes it a particularly problematic
weed is that it's difficult to control with herbicides.
Now there's two different aspects on that, the first one is it grows very quickly, so
with any weed species the larger the plant, the more difficult it is to control you just
don't get enough herbicide into it.
Second aspect is it stresses very quickly because it's a summer weed, it's in hot, dry
summer conditions it then makes it very difficult to control with herbicides.
In the seedling state, feathertop Rhodes grass can be identified by its flattened stem.
When it's very small and you may have something like barnyard grass or windmill grass, all
in the same population, it can be difficult to distinguish but once it gets to probably
about a three to five centimetre stage, it has quite a predominant flattening of the
stem.
Feathertop Rhodes grass prefers to germinate above about 25 degrees celsius up to about
35 degrees.
It does need moisture for only about two to three days for germination.
In summer, if you're getting rainfall over a couple of days and if it's enough to keep
the soil moist, you'll get a flush of emergence.
The seed of feathertop Rhodes grass is fairly short lived in the soil so it's one of those
weaknesses that we can really take advantage of.
Seed that's on the soil surface, most of it's gone after 12 months and the good thing is
seed that's buried most of that is also gone after 12 months.
So if you can stop seed set and replenishment of that soil seed bank for 12 months, you
should be able to get onto the feathertop problem quite quickly.
Herbicides still remain a critical component of managing feathertop Rhodes grass, but the
key to effective herbicide application or use on this species is to apply it to small
plants.
Once you get to the tillering stage, the efficacy of any herbicide treatment whether that's
applied alone, in mixture or as a double knock, that efficacy drops off once you get to the
tillering stage with feathertop Rhodes grass.
Once feathertop Rhodes grass has gone beyond the tillering stage, herbicides are really
quite ineffective in its control therefore you have to resort to things like hand removal
or chipping which is an approach that can be used if you've got a low density of feathertop
in your fallow.

Chelsea transfer news: Blues odds-on to complete Pulisic deal ahead of Liverpool - Duration: 3:26.
Reports yesterday claimed the Blues have opened talks over a summer move for the 19-year-old
The Bundesliga giants are demanding around £65m for the USA international if the forward decides to quit Dortmund
Liverpool are also in the hunt for Pulisic, however, Chelsea are determined to beat the Blues to the attacker
And the bookies say the Blues are odds-on to sign Pulisic, with Liverpool next in line to swoop for the Dortmund star
Betway's Alan Alger said: "Christian Pulisic may only be 19, but he already has over 60 appearances for Borussia Dortmund and more than 20 caps for the USA and has impressed many in his short career
"Chelsea look to have jumped to the head of the queue for his signature and are the 4/5 favourites to be the club he ends up at after the summer transfer window
"He's 6/4 to remain at Dortmund, while he's 5/2 to move to Liverpool, which would see him reunited with Jurgen Klopp, the manager who engineered his breakthrough at the German club
" With Chelsea and Liverpool battling for Pulisic, ESPN FC pundit Paul Mariner reckons the Dortmund star should join the Reds over the Blues
He said: "It's very attractive to go to Chelsea. "It's very attractive to go to Liverpool
I just think he's got to be careful of where he goes. This is a very important move
"If he goes to Chelsea, what happens generally to players that go to Chelsea? They get sent out on-loan again
"Can he break into the side? Can he take (Eden) Hazard's spot? Of course he can't
Can he take Willian's spot? No. He's not going to play him through the middle. "The people looking after him have got to be very, very careful
"This is an incredible move for Pulisic if he goes to the Premier League because the marketing side of the game, particularly in the USA, the club will make millions of dollars
"Looking at it purely and simply from the player's viewpoint, I'd stay at Dortmund for another year
"But if I was going to go, I'd go to Liverpool. He knows (Jurgen) Klopp, Klopp knows him, he'd be fantastic to come in and out for (Sadio) Mane and (Mohamed) Salah
"I think that would be a better move."
