Chief Health Plant Officer Dr Anne Walters says surveillance is being ramped up after further detections of Guava Root-Knot Nematode in the Territory · 360 with Katie Woolf

• 0:00
  Speaker 1: We know that surveillance is being polstered to manage an
• 0:02
  Speaker 1: aggressive pest worm which has been found at more sites
• 0:06
  Speaker 1: across the Northern Territory. Guava root not nematod, which can
• 0:10
  Speaker 1: destroy fruit and vegetable crops, was first detected in Darwen
• 0:14
  Speaker 1: last month, and Chief Health Plant Officer Doctor Anne Walters
• 0:18
  Speaker 1: joins me on the line right now to provide a
• 0:20
  Speaker 1: bit of an update on the pest. Good morning to you.
• 0:25
  Speaker 2: Hello, honk going, yeah, really well.
• 0:26
  Speaker 1: Thanks so much for your time this morning. And now
• 0:29
  Speaker 1: how many sites has the pest been detected at now
• 0:32
  Speaker 1: and whereabouts are they?
• 0:35
  Speaker 2: Yes, was now detected at seven Conferm Science. When I
• 0:39
  Speaker 2: first spoke to you about this last month, we talked
• 0:41
  Speaker 2: about the facts that it was that middle Point Malach
• 0:43
  Speaker 2: and Palmestan and Rapid Creek, but we've now also founded Atenora,
• 0:47
  Speaker 2: Leana and on Croker Island.
• 0:50
  Speaker 1: Right now, can you just remind us about the nematod
• 0:53
  Speaker 1: and its impacts.
• 0:56
  Speaker 2: Yeah, So it's a microscopic pest, so you can't see it.
• 0:59
  Speaker 2: It's a round worm and it lives in the soil
• 1:02
  Speaker 2: and the impact on the plant is that it affects
• 1:04
  Speaker 2: the roots of the plants, and the plant's response is
• 1:07
  Speaker 2: to create these knots on their roots, which is hence
• 1:10
  Speaker 2: the name guava root, not nematodes. And it's when the
• 1:14
  Speaker 2: plant starts to fail or die that people start to
• 1:16
  Speaker 2: remove their plants and see these gauls or not on
• 1:20
  Speaker 2: the roots of the plant. And that's when you know
• 1:22
  Speaker 2: that this is likely to be the pest that you've got.
• 1:24
  Speaker 1: And what does it you know, what does it do
• 1:26
  Speaker 1: to the plant? It sounds as though it does have
• 1:29
  Speaker 1: quite a bad impact. What does it do and what
• 1:31
  Speaker 1: does it mean for territorians at this point, Yes, it burrows.
• 1:36
  Speaker 2: Into the plant and then the plant responds, but obviously
• 1:39
  Speaker 2: in responding it puts a lot of energy into you know,
• 1:42
  Speaker 2: trying to find what this invasive thing is it and
• 1:45
  Speaker 2: it often more than starts to fail, it's not as
• 1:47
  Speaker 2: healthy in some cases that will die. So it really
• 1:50
  Speaker 2: is a significant test. Like I said, you can't you
• 1:54
  Speaker 2: don't know it's there unless you start to see the
• 1:56
  Speaker 2: plants that it likes to feed on affected, and that
• 1:59
  Speaker 2: things like cucumbers and tomatoes and a whole range of
• 2:02
  Speaker 2: other things. And so what we're I guess suggesting is
• 2:04
  Speaker 2: that people are really careful, and they're moving plants and
• 2:06
  Speaker 2: soil around in particular because you can easily move this
• 2:09
  Speaker 2: pest around, and we're suggesting that if you're using machinery
• 2:13
  Speaker 2: or equipment or even with your boots, just making sure
• 2:15
  Speaker 2: that you clean those between moving from site to science.
• 2:19
  Speaker 1: Now I understand that obviously surveillance is being ramped up.
• 2:22
  Speaker 1: What exactly does that involve.
• 2:25
  Speaker 2: Yeah, so we're looking at doing surveillance obviously, but we're
• 2:28
  Speaker 2: also really keen for people to let us know it's
• 2:31
  Speaker 2: so suspicious that they might have it, or they'd like
• 2:33
  Speaker 2: to get us to come and have a look at
• 2:35
  Speaker 2: some plants that they're worried about or whatever. And we're
• 2:37
  Speaker 2: getting people just to call us in on one eight
• 2:39
  Speaker 2: hundred zero eight four eight eighty one. And like I said,
• 2:42
  Speaker 2: so we're taking samples, but we're also going to be
• 2:44
  Speaker 2: doing our own surveillance, particularly commercial properties, just to make
• 2:48
  Speaker 2: sure that the growers know what to look for and
• 2:50
  Speaker 2: what to report, but also that their biosecurity practices are
• 2:53
  Speaker 2: really well in place and so that they can reduce
• 2:55
  Speaker 2: the risk that this pest will come onto their property.
• 2:58
  Speaker 1: And at this point, have any of those commercial growers
• 3:01
  Speaker 1: like are they impacted at this point in time.
• 3:05
  Speaker 2: No, well, we've got one commercial grower that's impacted, and
• 3:08
  Speaker 2: that was actually how we first detected the pest. So
• 3:11
  Speaker 2: obviously growers out all the time, they're looking at their crops,
• 3:14
  Speaker 2: and this particular grow was concerned about his cucumbers and
• 3:16
  Speaker 2: he contacted us and we went down and that's how
• 3:18
  Speaker 2: we first had the suspicion that we've got this particular
• 3:21
  Speaker 2: and in the toad in the territory. Yeah.
• 3:22
  Speaker 1: Right, And so how is a grower like that being
• 3:25
  Speaker 1: supported and how those other growers being supported to sort
• 3:28
  Speaker 1: of I know you said you'll be some of your
• 3:30
  Speaker 1: team are going to be heading out and educating them
• 3:33
  Speaker 1: and chatting with them about it. Is that how they
• 3:35
  Speaker 1: are going to be supported?
• 3:37
  Speaker 2: Yeah, And one of the other things that we're really
• 3:39
  Speaker 2: interested in doing is getting a project up to see
• 3:42
  Speaker 2: if we can better understand whether there's ways that we
• 3:44
  Speaker 2: can manage this pest most effectively. So we will be
• 3:46
  Speaker 2: working in the industry on that as well. And this
• 3:49
  Speaker 2: particular grower, the first founder, is really keen on being
• 3:52
  Speaker 2: involved in that type of research so that not only
• 3:55
  Speaker 2: is he able to protect his own fun but also
• 3:57
  Speaker 2: that of others.
• 3:58
  Speaker 1: Yeah, and what should those grow, Like, what are they
• 4:01
  Speaker 1: on the lookout for, and what's your message to them?
• 4:04
  Speaker 2: Yeah, I guess the thing that we're really suggesting is
• 4:07
  Speaker 2: just be really vigilant with the things that you bring
• 4:09
  Speaker 2: onto your property. So it might be things like, you know,
• 4:12
  Speaker 2: you're bringing new plants on, perhaps quarantine them for a
• 4:14
  Speaker 2: while and make sure that they're not infected with something,
• 4:17
  Speaker 2: that the plants are healthy when you actually introduce them
• 4:19
  Speaker 2: into your system, because as soon as you introduce the soil,
• 4:21
  Speaker 2: it's really difficult obviously, So if you've got contaminated soil,
• 4:24
  Speaker 2: then you're introducing it into your system and that means
• 4:26
  Speaker 2: that you're more likely to spread this pest. So it's
• 4:29
  Speaker 2: suggesting that anything that has soil attached to it just
• 4:32
  Speaker 2: to be really careful of when you're bringing it onto
• 4:34
  Speaker 2: your property. Like I said, if you can wash things
• 4:36
  Speaker 2: and clean them, that's the best approach.
• 4:38
  Speaker 1: And is the Northern Territory working with other jurisdictions as
• 4:41
  Speaker 1: well to try and manage these Yeah.
• 4:44
  Speaker 2: Well, at the moment they're othern Territory is the only
• 4:46
  Speaker 2: one that's got it.
• 4:47
  Speaker 1: Yeah.
• 4:47
  Speaker 2: One of the things that we have suggested to other
• 4:49
  Speaker 2: jurisdictions is that they do since surveillance themselves just to
• 4:52
  Speaker 2: check out whether they might have it. But the other
• 4:54
  Speaker 2: thing that we are suggesting is that they go back
• 4:56
  Speaker 2: through their historical specimens and just make sure that they
• 4:59
  Speaker 2: didn't misdive those, which is really easy to do because
• 5:01
  Speaker 2: this pest is so closely related to other species, so
• 5:05
  Speaker 2: there is a possibility of misdiagnosis. So we are working
• 5:07
  Speaker 2: with other jurisdictions to help them to do the surveillments,
• 5:10
  Speaker 2: but also to make sure that they've got the diagnose
• 5:12
  Speaker 2: gnostics right in case they do have this pest themselves.
• 5:15
  Speaker 1: Yeah, well, I guess that could be the concern for
• 5:18
  Speaker 1: them is that they actually do and don't realize at
• 5:20
  Speaker 1: this point.
• 5:22
  Speaker 2: Yeah, that's right, because given how widespread is in the
• 5:24
  Speaker 2: Northern territory, you know, we're talking from Middle Point through
• 5:27
  Speaker 2: to Croak Island, it is really widespread. It suggests that
• 5:30
  Speaker 2: it's been here for some time, and that also suggests
• 5:33
  Speaker 2: that there has been a possibility that it could have
• 5:34
  Speaker 2: been moved to other places inadvertently.
• 5:37
  Speaker 1: And also, I guess the question that people are going
• 5:40
  Speaker 1: to be wondering right now as well an is how
• 5:42
  Speaker 1: do we sort of end up with it in the territory.
• 5:46
  Speaker 2: Yeah, it's a really hard one and I don't know
• 5:48
  Speaker 2: if we'll ever know the answer to that. It's a
• 5:49
  Speaker 2: really big problem in plant bio securities often that we
• 5:52
  Speaker 2: can't work out where things have come from. So at
• 5:55
  Speaker 2: this stage we haven't got anything that we can say
• 5:57
  Speaker 2: it was from this situation. It can be someone coming,
• 6:00
  Speaker 2: you know, with something that they didn't even realize that
• 6:02
  Speaker 2: they might have been carrying the pest from overseas. But
• 6:05
  Speaker 2: also if it is in another location domestically, it's possible
• 6:08
  Speaker 2: that is coming through there, but at this stage there's
• 6:10
  Speaker 2: nothing to suggest it is present in those places, and
• 6:13
  Speaker 2: like I said, we're just supporting those other jurisdictions to
• 6:15
  Speaker 2: help them to do that surveillance.
• 6:18
  Speaker 1: Well, Chief Health Plant Officer, Doctor Anne Walters, we always
• 6:21
  Speaker 1: appreciate your time. Thanks so much for coming on the
• 6:23
  Speaker 1: show this morning.
• 6:25
  Speaker 2: It's always a pleasure. Thank you, Thank you,
