Herbicide tolerant canola here in 2015

It will be good to be able to have some flexibility in terms of chemical rotation

AUSTRALIA'S first dual herbicide tolerant canola varieties are set to be released next year.

A canola with both triazine tolerance (TT) and Roundup Ready (RR) traits will be available through Pacific Seeds. The combination of traits will be known as 'RT'.

Farmers are excited about the new technology, saying it will provide a good suite of tools in terms of weed management.

"It will be good to be able to have some flexibility in terms of chemical rotations, and it will help prevent herbicide resistance," said Victorian Farmers Federation (VFF) grains group president Brett Hosking.

"Obviously, the varieties will have to stand up in the field, but it is good to see this kind of research and development."

Pacific Seeds canola technical manager Justin Kudnig said his company had tried to get industry to have a look at the variety while it was in the trial phase.

"Over 500 agronomists and consultants representing over 80 per cent of advisers and resellers have visited the trials evaluating RT Technology," he said.

Mr Kudnig said they were impressed with the visible efficacy of the technology.

He said there were already good orders for next year for the variety.

Pacific Seeds and Monsanto have developed the technology as part of an integrated weed management strategy.

Mr Kudnig said the combination of Roundup Ready herbicide and triazine herbicides traits will provide growers with the broad spectrum knockdown control of Roundup Ready, along with the residual activity of the triazine herbicides to control a wide range of weed species including annual ryegrass and wild radish.

He said the two herbicide groups to be used in the RT system complemented each other well, with glyphosate providing good immediate results and the triazine herbicides giving a residual control.

The first two products in the Hyola RT line-up are Hyola 525RT and Hyola 725RT.

As mentioned in the article, the plant will need be stable in broad acre trials. Also, the buyer will need to WANT IT. Lastly will the farmer be able to keep his own seed for a couple of seasons at least?

Your Nic suits you Mug. Why would any farmer want to keep hybrid seed given the yeild reduction costs far more than new seed. Buyers want GM canola, check out today bid sheet, thats if you can wrestle off your blinkers.

You miss the point Boris. You are trying to change a proven system that has worked well for ages. Hybrid seed is not always the answer. However hybrid seed suits the plant breeder very well as he gets a captive market for new seed each year. Another thing to remember " Sarcasm is the wit of a fool" Do yourself a favour and look at the BIG picture--not your immediate quick quid.

Of course it suits the plant breeder but his product must make farmers more profit, which it does, then the breeder captures a profit also. Capatalism delivers the big picture which is a win win for the producer and consumer. Your way is to stop farmers having choice by way of you being a gate keeper. How totalitarian of you.

Well the plant obviously is going to have the TT yield penalty, so having Hybrid vigour is going to be important. Will be interesting to see where this fits in the system, obviously a useful tool if coming up against weedy paddocks.

Interesting discussion but no mention in the article about the new canolas being hybrid varieties capable of delivering hybrid vigour. Is there background info to this story that is missing in the text that I am unaware of or are the readers using imagination?

Seems boris is the only logical head on this thread. 525 is a hybrid similar to 404. Although it carries the TT yield penalty, its weed control capacity beyond RR means that growers can avoid $60/ha of cost in swathing and end of season croptopping. Seed is likely already sold out.

Dreg, how does the double R remove the swathing need? Interested in the answer as a non canola grower.

The residual control of a robust atrazine rate, or combination with Terbyne, gives a much longer period of total weed control such that what few weeds are there, are tiny and totally uncompetitive come normal swathing time. There is also a new variety out this year which has the PSR gene which stops pods from shattering . Exciting benefits flowing to those States able to grow GM. Poor old SA will have Sakura and Boxer Gold resistant ryegrass before they can help mitigate the risk with GM tolerant canolas.
