Anyone use Moddus on spring barley?

[WRXppp]

As the title says, has it been a success, pro’s and con’s please, I seem to always get lot’s of brackeling and a degree of root lodging.

used to use about 0.08l/ha early to promote rooting

Of moddus?

@Brisel has made previous comments regarding perceived rooting effects being incorrect I believe.

If you stop the top growing I guess it can only produce roots!

 

[eagleye]

was on the advice of experienced agronomist! yes Moddus
correction should of course have been 0.08 litre/ha

Proven not to promote rooting. Agronomists are often wrong or get given mis-Information

Moddus is a good product, but it’s for growth regulation not to promote rooting or tillering. That’s just a sales drive.

It was useful on spring barley when there weren't any chlormequat products approved for the crop.......

Useful product, however the best options for reducing brackling are Terpal and ensuring plant has sufficient potash!

What PGR's are proven to promote rooting and tillering? (thinking more along the lines of wheat tbh...).

We stopped using Moddus on winter barley full stop, as we got the impression it was reducing yield. Come to think of it, we stopped growing barley not long after, as it was reducing whole farm profit.

None of them! The clue is in the title... Try nitrogen plus phosphate if you want good roots & tillering

Kept hearing the PGRs enhance rooting thing in the past. Lot of people I met were sceptical of this and I never claimed any PGR did this myself. I know some agchems do cause plants to root harder but they were never marketed in this way for whatever reason.

Potash supply for barley is very important and if you time one application of anything right all season it has to be your terpal.

And roll it. Twice.

Couldn’t agree more (adding variety choice to that list)

So terpal just before awn emergence rate dependant on lushness of the crop, most land for spring barley here is mucked and after stubble turnips we are on index 2 and 3 so potash should be ok?

You have outlined the majority of the situations in which I have grown wheat or barley. Generally good P and K indices but also generally fertile areas with large historic manure applications.

I have tried a myriad of PGR options, played with nitrogen rates, different varieties and in barley I can safely conclude that basically if a crop falls over or not in the months preceding harvest it is largely in the lap of the gods. If you get those freak summer rainstorms and a lot of wind it's a near bet the stuff will be bent over come cutting time.

I should say that I have in the past given spring barley a go with moddus or chlormequat in the past, and then done terpal later (at the usual timing). Where I have done early PGRs it was always very early (I seem to remember the 3C label advice was by GS 14?? but may be totally wrong). Normally I would put it in with some manganese as by this time few weeds had really emerged. I have experimented with foliar applications of nutrients as well, some of which have included small amounts of potassium. I can't tell you if this really was a deciding factor as I just wasn't in the job long enough nor doing thousands of acres of spring barley to give a valued judgement.

Good Afternoon,
I am looking for cereal growers and agronomists to give their thoughts on a potential digital tool that could help alert growers to when to apply PGR's to their cereals when lodging risk is increased. Below is a link to a quick questionnaire:

We value your opinion and continue to direct our efforts towards finding tailored solutions for you. Thank you for taking the time to complete this survey.

Optimus is a better version of same active
Modus can be harsh on a crop, I’ve used it on SB before if it’s a weak variety to stand like Planet won’t do enough
I’ve honestly found Medax Max more use that straight modus

 

[Brisel]

Medax Max has prohexadione, another PGR, as well as trinexpac
