Will have a prochloraz + tebuconazole product in store just in case there’s any rain on the horizon. Skyfall and Montana will be flowering next week. The way the forecast is looking, it will probably all get returned.
Doesn’t it make don worseAmistar. Maybe something else.
Personally I feel after the horrendous 2012 fusarium & michrodochium wheat infections, the amount of inoculum returned to the soil has intensified stem base & ear infection intensity if the conditions are at all conducive. Surprising after such a dry spring, how much nodal fusarium is about.What prior to 2012 would have led to a bit of ear disease, now leads to 3, 4, 5 lost grains. 10%!! Varietal resistance is either strong like Leeds, reflection-or average(ie not great) most other vars, or catastophic-Cougar, which was areal shame as otherwise it was a great variety, but chance of a bit of rain at flowering, and you had a tonne/ha down the drain.
Planning teb, but will have proline in the store if turns wet, with phosphite for seed crops. Mix with amistar I would imagine as a standard.
Doesn’t it make don worse
I don't expect I can hit the wheat at the optimum time for don anyway given rapid development ; forecast wind speed......and sprayer in the workshop.
Hadn't heard it makes don worse. I'm hard pressed to do much more than half a litre of teb, but I have amistar and comet in the shed and some is quite old already!
You think innoculum is active 7 years later ?
Definately seen more prevelant fusarium stem based disease since 2012, rather than before. Previous worst year I recall(not exclusive as depends where you farm) was 1998. Now find nodal fusarium after fairly innocuous weather whereas previously needed properly wet times. No scientific validation, purely observation.
No rain at all here ATM. All quality wheats, but I'm thinking 0.75 - 1.0 l teb.
Can't bring myself to spend £24 ha + on a prothio based spray.
Any views?
Same here Chalky...lots of wheat drilled in chopped wheat straw with a Claydon. Agronomist and I were surprised / ambushed by the amounts we could see.
Luckily appears to have stalled out just in time, but it was close.
I've got prices for it anyway!I thought Prosaro wasn't around anymore.
No difference between prothio & teb for fusarium on the ear, both can only offer around 50% control even at full dose.
Proline and teb here for around £19/ha. 3 weeks after the flag spray at mid flowering. Some a sniff of foliar K too as I haven't had enough rain to wash the MOP in & I've been using less pgr this year in the dry weather & want stiff straw.
Compared to Kestrel at 0.6l/ha, how much ai are you getting for your £19/ha
