Friday 15 November saw the end of the second short course for African participants on small scale irrigation and water harvesting at the University of New England, Armidale.

Lecturer Isa Yunusa encourages the group to strive for great thingsThe five weeks of activities culminated in a great dinner and presentation of certificates at the beautiful Moore Park Inn. There were mixed emotions as the night progressed. Our friends were keen to get home to see their families and get back to their normal lives yet felt they would miss the companionship that has grown during their stay.

Their training is not complete however. They have action plans developed and refined during the course which they will begin to implement when they arrive home.

In February 2014 we will meet both groups from this year in South Africa where we will refine their projects and study successes and problems encountered by small landholders in the Limpopo Province.

I am very lucky to have such a diverse job.

Last week my colleague Peter Fitzgerald from the University of New England and I were tour guide, bus driver, trainer and very much everything in-between with 15 African agriculturalists from 11 different countries. We visited Gunnedah, Dubbo, Narromine and Nyngan as a major part of our second 2013 “Irrigation and small scale water harvesting course” based at the University of New England and funded by AusAID.

• refining extension techniquesand project planning
• dam building with the Soil Conservation Service
• irrigation systems with Lew Hyson and Isa Yunusa (UNE)
• field tour of irrigation, water spreading and water ponding

The field tour is a highlight as our friends get to meet a range of Australian farmers with a range of management styles and ‘drivers’ as well as getting practical training on establishing water spreading banks and water ponding at Nyngan with Ray Thompson, Local Land Services.

A sad farewell to the gateway to the Outback

The Grains Research & Development Corporation have just released a series of succinct videos on producing and burning narrow windrows. While set around Geraldton the principles apply everywhere.

For a more southern Australian experience see what Doug Smith has been doing at Pingrup in southern Western Australia.

Just received the official Quick-test® results on the paraquat resistant ryegrass from the southern WA vineyard and low and behold, we also have moderate glyphosate resistance.

The virtual loss of the two main knockdown herbicide modes of action begs the question about longer term weed management in all vineyards. The owners have recently used a robust rate of Fusilade® to kill the ryegrass. I have suggested however that while this solves a short term problem Group A herbicides should not be used by themselves in the longer term.

This situation is an excellent example of how rotating herbicide modes of action only delays the development of resistance while creating multiple resistance in the longer term.

What must be used is a series of tactics (herbicide and mechanical) within a season that ensures that potentially resistance survivors of the previous tactic are prevented from setting seed. This is the ONLY way you manage herbicide resistance. Ensure you always use the higher end of the herbicide label rate with the best possible application methods and under the best possible conditions.
