 World's best cotton yield must get better 

World's best cotton yield must get better

14/08/2008 12:11:00 PM
The Australian cotton industry has been told it must rapidly increase its already world-leading yield, with a deadline to do so by 2022.

This is the date projected to be the crunch period when the bales/hectare required to "break even" will overtake the projected gains in yield in new varieties.

Such was one of the key messages at this week's Australian Cotton Conference on the Gold Coast, where 800 delegates gathered to discuss the industry's future.

But despite the grim prediction, delegates on Monday heard that all is not lost.

Visiting Monsanto cotton technology lead from the US, John Purcell, told growers about new traits in the pipeline that will help meet these necessary yield gains.

Dr Purcell (pictured) said that the next generation of biotech traits in cotton would shift from insect and weed management to more specific agronomic advantages.

Of most note for Australian producers, will be water use efficient (WUE) cotton, which should yield 10 percent more cotton in drought stress situations, or deliver 20pc better WUE in full-water situations.

Also, Monsanto is also working on traits that branch further from its Roundup Ready varieties to further combat herbicide resistance.

"At the end of the day, so many of the traits that we talk about are about getting maximum yields," Dr Purcell said.

While he noted that many numerous traits are possible, growers should not hold their collective breath waiting for all of the possibilities.

"It is a 10 to 12 year process and a $100 million development cost for a new trait.

"At that cost there aren't that many opportunities that we can take advantage of that we can make pay in the end."

However, Emerald, Queensland, consultant, Dave Parlato, noted there are important points to consider before immediately getting excited about such "super crops".

He said it is important that growers think about what traits they specifically need, as an increase in traits will inevitably lead to increased costs.

He said while growers have to court new technology - and also have to ensure that suppliers make a profit - there is a risk associated with having all the eggs in one basket.

"At the moment we have one insect tolerant cotton trait and one supplier," he said. "Are all our eggs in one basket?

"If that's the case, we have to be careful we don't get fried."

Super Bugs, super Weeds, this is not what we need.

Monsanto developed an insect-resistant type of cotton called Bollgard that's planted in more than 90 percent of Georgia's cotton fields. But, the company is phasing it out because of concerns that insects could develop a resistance, and that could create super bugs. Their Bollgard 2 also resists insects, but it doesn't yield as much cotton. And, that could mean a 60-million dollar loss of net income for farmers.

Gene escapes to weeds from engineered canola - edited a recent study published in the scientific journal Molecular Ecology found that canola plants in Quebec, Canada, that were genetically engineered for herbicide resistance have interbred with a weed called wild mustard, producing hybrid plants that are resistant to the herbicide glyphosate. The herbicide-resistance gene persisted over five generations and spread from the hybrids into the mustard weeds, in spite of the fact that no herbicide was applied to the area. The event is significant for two reasons.

One, it is the first known escape of a gene from a commercialized genetically engineered crop into a weed. Two, because canola is a major crop, covering an estimated two million acres across Canada, it is likely that gene escape has occurred at multiple sites in addition to the few that were monitored. The event echoes the escape of a gene for glyphosate resistance from field trials of bentgrass into wild relatives.

Cotton experts struggle to control pigweed. The nasty weed can grow 6 to 10 feet tall and is resistant to many herbicides including glyphostate.

Cotton farmers are having a terrible problem and will change chemicals or lose their farms to weeds. In 2008, the weeds are winning. Farmers are using multiple herbicides.

Some farms in Georgia have been abandoned because of pigweed. Palmer amaranth (pigweed) overwhelms cotton plants by robbing sunlight, nutrients and water. Only expensive chemical treatments have worked on resistant pigweed. Overuse of glyphostate made the pigweed resistant. Weeds are very adaptive .

This headline assumes of course that Australian farmers will continue to have to operate without subsidies against subsidised competition.
