T3

[An Gof]

Is anyone else just doing nothing ?
It’s getting , no got, ridiculous how much we have to nurse these crops through to harvest. Ok, it’s rained hard for a few days, but not for weeks on end. If the weather looks warmer and more settled next week, I’ll be shutting the gate .

If you had suffered a 2012 like we did you wouldn’t risk all the investment you have already put into the crop for the cost of a T3 now. @teslacoils considered you brave, I might be thinking of something else

 

[teslacoils]

I suppose the bravery comes from the gamble. You've probably missed the timing for mycotoxins. You've probably missed any protecting timings after the recent rains. Will the weather be conducive to disease that 0.5 of teb will stop?

I've got 300ac that wasn't ready for t3 pre rain. It will get done middle of next week. Will it be timed right? Unsure. Will it result in more yield than cost of the chem? Quite probably. So it goes on. I am not brave.

Does no-one not remember the biggest yield robber of 2012? Wet year-yes; but wet flowering period! We had crops with 4 clean leaves here (seed crops) through priority spraying, but because of wet flowering period and poor fungicide timing I would suggest the ear disease loss far exceeded foliar disease & lack of photosynthetic opportunity. Pre rainy week(that had been forecasted-but somewhat wetter than expected) teb, ptz, az; post rain-a week- phosphite added as the only curative I know for fusarium. The real yield robber is michrodochium, for which only ptz is an active protectant. It has been on the stem base because of the dry spring(which is somewhat counterintuitive as ear issues are associated with wet periods) so am treating the risk thus.

 

[teslacoils]

I'm unsure. Yes, it has been wet. But once a wheat ear is wet can it get more wet? I mean what's the difference between three wet days producing one inch and three inches to an ear of wheat? What I'm saying is while we have had a lot of rainfall we haven't had many days of wet and dull. And it may well be back to nice low twenties for a week.

So having done a well timed t3, I must admit I'm going to do a bit more research on fusarium and microdocoum.

I remember it only too well. Average wheat yield here in 2012 was a pathetic 4.5t/Ha

I have already had a conversation with NIAB Tag about the possibility of a T4 if this weather continues after remembering the dreadful impact of 2012. Their view is that there is little to be gained. It’s the timing of the T3 that is critical. Some posting on this thread have missed that as they delayed because the “crop was clean”
With fusarium it’s all about protection and prevention not eradication.
@Fromebridge saw the devastation we suffered from this in 2012 in the far SW.

 

[Mr Charisma]

My wheats of which are mainly quality wheats all had a well timed T3 applied between the 3rd and the 5th , timing was about right ,
Wheats look fantastic but have a long way to go , so has the spend finished now ,,,,,, I hope so or T4 maybe ?
I am no agronomist or no expert all I know is that 2012 was the most miserable harvest of my life !!!!!!! Crops that at this time looked like producing 4 ton / acre from field to field in fact produced nearer 4 ton / ha so with reason I'm very cautious !!!!!!

Edit. Just seen An Gof's post

We suffered badly in 2012 also, but my thinking is that we’ve missed the boat anyway , as the weathers been too wet to travel . I haven’t seen anyone out spraying wheat locally, obviously due to the 6 inches of rain we’ve had in the last week.

Did the weather forecast catch you out or was it just that it was to early for a T3 when the weather broke ,,,,,, I was lucky I suppose in that all bar 1 field I had perfect timings although the forecast did make me get my finger out to get it all done

Chin up, it’s not the volume of rain more the frequency and persistent periods of high relative humidity.

When I went on holiday , they weren’t ready for an ear wash. It’s chucked it down ever since

 

[yellow belly]

I do wonder that when rain is so intense 30 mm in a couple of hours that some disease spores get washed onto the ground and cannot get wind blown back onto the crop

septoria can be rain splashed about but if enough water fall to the ground does it wash it of
dust on leaves can be washed off

hard to prove or disprove

 

[Wombat]

If the wind drops a bit tomorrow I will finish the rest of the T3 tomorrow as the ear wasn’t fully out last Monday when I did the rest

 

[MrNoo]

Well, it will be interesting here as 70% of the wheat was mid flower and the later drilled stuff was out in ear but not started flowering, I sprayed it all just before the rains came along with a lot of others in the area. Not sure I will be going through it again but never say never!!

 

[4course]

I will nag the agronomist tomorrow, I have it in stock, if it will help I may as well use it.

what was your mans opinion

 

[Two Tone]

Microdochium Nivale is the cold, wet weather Fusarium. It is very difficult to control, only by preventative fungicides tebuconazole plus prochloraz, which often at best will only achieve a 50% reduction.

This is what we suffered in 2012. However, I don’t think it has been as cold this June as in 2012.

On this farm, it halved the yields we saw in 2011. Lorries left the farm short of weight and we had huge claims for low bushel weights.

On top of which, the Combine kept getting stuck!

We are going to be later than I would have liked with T3 because of the weather, is there any evidence that phosphites have any eradication effect on fusarium? My agronomist has suggested using it at this stage in the past. Was going to be using teb, ptz and az myself.

 

[Chalky]

Yes.

Phosphites are probably going to be reclassified as fungicides in the long term. Downy mildew, fusarium & several other pathogens give activity.

FML forecast yesterday was for three days dry, then drizzly Wednesday, then dry. Now changed to crud. So glad I'm almost out of this stupid job.

Yes, it’s supposed to be dry here, but the heavens have just opened.
What’s the career change ?
