Prof Wijnand Swart believes a ‘systems level understanding’ of phytobiomes (consisting of plants, their environment, and all their associated organisms) will enable us to produce sufficient crops to meet global demands while minimising negative impacts on our environment.

Plant health is important for the survival of our planet and all its living creatures. Now, imagine an instrument that contains a DNA chip from virtually every known plant pathogen, where one can simply snip off a piece of the infected plant material, slip it into the ‘plant disease tricorder’, and within seconds you have not only a diagnosis of the disease, but all the information about its control too.

According to Prof Wijnand Swart, Professor of Plant Pathology in the Department of Plant Sciences at the University of the Free State (UFS) and President of the Southern African Society for Plant Pathology (SASPP), this concept might be a bit far-fetched, but is a distinct possibility for the not-too-distant future. “Without a doubt …,” he believes.

He was recently a guest on a series of radio talks on plant health in South Africa, hosted by the National Science and Technology Forum (NSTF) in partnership with Plaas/Farm TV (YouTube broadcaster). His talk on the topic, Whither (or wither) Plant Pathology in the next 50 years, was specifically focused on understanding the latest research and dynamics of the discipline in a South African context.

In terms of this futuristic perspective, he says collaboration between plant pathologists and biomedical and aeronautical engineers, nanotechnologists, and computer scientists will aid the development of micro-sensory technologies for the detection of new plant diseases that are relevant to biosecurity, plant disease diagnostics, and epidemiological modelling.

In his discussion, Prof Swart referred to the work of Prof John Lucas, former Head of Plant Pathology and Microbiology at the Rothamsted Research Station in the United Kingdom, who believes that there are three key issues facing plant pathologists in the 21st century. These are the strengthening of food security while simultaneously safeguarding the health of associated ecosystems and reducing the dependency on natural resources; the creation of pest and disease control systems that are sustainable and not compromised by the evolution of pest and pathogen strains; and the development of suitable crop protection technologies.

Future technologies

Based on the work of Prof Lucas, Prof Swart states that future technologies in plant health will develop in five areas. In the first area, he says DNA-based technologies will greatly increase the speed, sensitivity, and accuracy of pest and pathogen detection and diagnosis.

Also key here, is the integration of nanomaterials into disease management strategies and diagnostics. He says in the past decade, the use of nanotechnology in phytopathology has grown exponentially. According to him, nanotechnology can increase productivity using nano-pesticides and nano-fertilisers, improve soil quality by means of nano-zeolites and hydrogels, stimulate plant growth using nanomaterials, and provide smart monitoring via nano-sensors and wireless communication devices.

Prof Swart says according to Prof Lucas, the second area in which plant health technologies will grow is plant defence and immunity. When induced, plant resistance primes plants to deal with a diversity of biotic and abiotic stresses. Prospects of inducing chemically modulated plant resistance via biological agents (such as engineered microbes), might result in low-cost seed treatments, thereby removing the need for expensive chemical spray regimes.

Technology development in plant health will also become more evident in genetic diversification. Prof Swart believes sequencing the genomes of major crop species and their wild relatives will expand the known gene pool and diversify genetic resources available to plant breeders.

According to him, a new era is beckoning, where the prospect of crop pharmacology based on signal molecules and their receptors will become a reality. It will be based on the development of novel chemistries designed to manipulate specific molecular targets, by either regulating host resistance or disabling the disease-causing processes of pathogens.

The fifth area in which plant health technologies will develop, is ecological approaches to disease control. He says by understanding the ecology of pathogens, our ability to exploit their natural enemies will improve. Ecological approaches to plant disease control will have a significant impact on the introduction of invasive pathogen species, while the effect of climate change will influence the emergence of new plant diseases and epidemics. He strongly believes that it is important to take a holistic approach to understanding how and why plant pathogenesis occurs if we are to manage diseases effectively.

Future challenges

The development of these new technologies is very important, as there are several challenges that plant pathology will face in the future. These include the increasing demand for food to support the growing global population; the decreasing production potential of agriculture due to competition for fertile land; the increased risk of plant disease epidemics resulting from agricultural intensification; the depletion of natural resources; and the influence of climate change on interactions between plants and their pests or pathogens.

Prof Swart believes a ‘systems level understanding’ of phytobiomes (consisting of plants, their environment, and all their associated organisms) will enable us to produce sufficient crops to meet global demands while minimising negative impacts on our environment.

He concludes, saying that plant pathology will evolve as an interdisciplinary science. He adds that future research will focus on new problems that are traditionally seen as outside the core discipline of plant pathology. Furthermore, food security will be a dominant and important driver of plant pathology research, while the impact of climate change on plant diseases will be very significant. Finally, that the adaptive potential of plant and pathogen populations will be one of the most important predictors of the magnitude of climate change effects.

Usual Suspects heading for USSA Hockey Week finals

30 June 2009

JONATHAN COOK
at USSA Hockey Week in Bloemfontein

THE University of Pretoria's Tukkies men and the Maties girls of Stellenbosch look to be set on defending their University Sport South Africa (USSA) hockey titles with success judging by the happenings on day two of the annual tournament at a crisp University of The Free State (Kovsies) in Bloemfontein Tuesday night.
This 34-team tournament is the biggest in the country after the Masters IPT.
In the top-tier Men's A Section, last year's winners the University of Pretoria (Tukkies) enjoyed a stunning 5-0 victory over University of Cape Town (UCT), who were the late-fightback 3-2 winners over UKZN on Monday.
After 38 minutes Tukkies were one goal to the good via the stick of Mark Holliday, but in the next 19 minutes mayhem broke out as coach Dave Viney's men from Pretoria pumped four goals past UCT. Holliday grabbed another goal from field play, with Nic Gonsalves and Michael Sykes joining the Pretoria boys' party, and Kyle Rhodes slamming in a penalty corner for good measure.
Last year's men's finalists the University of Johannesburg gained a crucial 2-0 victory against Stellenbosch in a battle of wits that saw SA U21 head coach Kurt Cerfontyne (Maties) and his assistant at the recent Junior World Cup, Garreth Ewing, in different corners this time round.
UJ went 1-0 up via a Dean Symons action goal in the 22nd minute – and the rattled Maties then had two players, David Wilson (26th) and Murray Clarke (28th) sent to the sin bin. A Miguel da Graca goal from a penalty corner made the game safe for UJ.
It looks like we are going to see another Battle of Gauteng among the men – Tukkies against UJ – in this year's men's USSA Hockey Week final.
And last season's talented SA U18 hockey striker Symons - alongside his equally talented national U18 team-mate and current UJ strike partner Marc le Sueur – could have a major say should that final come to pass at 7.30 pm on Friday.. 
In the women's A Section, the 2008 winners in Potchefstroom, Maties, were far too good for UJ, overwhelming the Johannesburg team in the second half.
Although they could only get one more goal after the interval through Spar SA striker Vida Ryan to add to Cindy Brown's first-half brace, Maties could have scored a good few more. Louise Coertzen scored UJ's goal that made the first-half-score read 2-1 to Maties.
However, UJ still have a chance to get to Friday's 6 pm final should they (likely) finish second to Maties in Pool A and qualify to tackle the Pool B winners in the semi-finals at 4.30 pm Thursday.
Last year's women's finalists, Tukkies, met North West and the score was 1-1 at the end after the Pretoria team had led 1-0 at half-time through Dirkie Chamberlain. Chantelle Bekker replied for Pukke.
In the B Section, host university Free State's ambitious women (Kovsies) beat University of Fort Hare 7-0.

RESULTS

Men – A Section: Tukkies (1) 5 (Mark Holliday 2, Nic Gonsalves, Kyle Rhodes, Michael Sykes) UCT 0; U of Johannesburg (1) 2 (Dean Symons, Miguel da Graca) Maties 0; UKZN (2) 3 (Duzo Khanyile, Karl Oftebro, Sihle Ntuli) Kovsies (1) 1 (Paul Jordaan); Nelson Mandela Metro U (0) 2 (Nathan Kops, Wesley Wittstock) North West (1) 1 (Matt Fairweather).

Women – A Section: Wits (2) 3 (Kirsten du Toit, Robyn Taylor, Robyn Johnson) UKZN (0) 1 (Nosipho Dladla); Maties (2) 3 (Cindy Brown 2, Vida Ryan) UJ (1) 1 (Louise Coertzen); North West (0) 1 (Chantelle Bekker) Tukkies (1) 1 (Dirkie Chamberlain); UCT (1) 2 (Deidre Potgieter, Keren Robertson) Nelson Mandela Metro U (0) 1 (Jocelyn Coombs).

Men – B Section: North Cape Urban FET 4 Vaal U of Tech 1; Tukkies B 5 Limpopo Turfloop 1; Vaal U of Tech 1 Pukke B 0; Wits 5 Kovsies B 2; Central U of Tech 2 N Cape Urban FET 1; U of Namibia 3 Cape Pens U of Tech 0; Rhodes 4 Tukkies B 2; Central U of Tech 2 Kovsies B 1; Wits 10 Pukke B 1.

Women – B Section: Rhodes 5 Pukke B 0; Tukkies B 5 Cape Pens U of Tech 0; Kovsies 7 Fort Hare 0; Pukke B 4 Central U of Tech 0; Vaal U of Tech 8 Limpopo Turfloop 0; Kovsies 7 Central U of Tech 0.


Cold weather doesn't deter hot hockey at Kovsies
Varsities hockey week on fire

JONATHAN COOK
at USSA Hockey Week in Bloemfontein

Despite the cold weather, there was much to warm the cockles of one's heart on day one of the University Sport South Africa (USSA) Hockey Week at University of the Free State (Kovsies) in Bloemfontein Monday.
In the Men's A Section (the first division), the fancied University of Pretoria (Tuks) beat hosts Free State Varsity (Kovsies) 4-0 after leading by two goals at half-time. All the Tuks goals were field goals with the scorers being Jonty Robinson, captain Brendan van Zyl, Simon O'Callaghan and Malcolm Ratz.
The University of Johannesburg clash with Nelson Mandela Metropolitan University (NMMU of Port Elizabeth) went down to the wire, UJ eventually prevailing 2-1.
After a goalless first half, UJ's Tebogo Lerole opened proceedings from a penalty corner and Joezay Kops equalised for NMMU with 12 minutes to go. The winner came after the final hooter had sounded, umpire Erik Etsebeth correctly awarding a penalty corner to UJ, which meant the set-piece had to be concluded, and Brandon Panther netted a great deflection goal for the winner.
The Maties men versus Pukke match saw the Potch boys start shakily. The Stellenbosch side under SA U21 head coach Kurt Cerfontyne were 3-0 up before the Pukke got back into the game. Although it was fairly even from this point, the Pukke caught fire too late in order to catch the Maties cold.
On a hot-blooded day for the umpires, who got heat from the players on the field and from personnel on the benches, both teams in this match were complimented for their well-disciplined benches.
Tuks' women and NMMU played to a goalless draw in the Women's A Section before University of Stellenbosch (Maties) outplayed University of KZN 8-0 after leading 3-0 at the break. Spar SA striker Farah Fredericks bagged a hat-trick with national team-mates Cindy Brown, Vida Ryan and Kathleen Taylor also getting in on the act.
The Pukke of North West University beat University of Cape Town (UCT) 3-0 with Chantelle Bekker, Lesle-Ann George and Princess Khuzwayo getting among the goals.
The University of The Free State is to be congratulated on a splendid venue, with synthetic turf hockey pitches side-by-side and including proper technical areas on both fields plus a festive clubhouse facility.
