Erm, maybe beginning of next week
Same here and I think T3 is just a don box ticking exercise but I will do the cheapest treatment I can to tick that box.
Need a week to dry out enough to travel here, and spraying maize is a priority , as the weeds are getting big enough
Luckily I sprayed some maize for someone early Sunday, it's a bit banky in a couple of fields would be fun trying now I reckon
Some might be saying........T4?
By those who cut back on T0,1,2 and 3? Or maybe just sellers of agchem?
Massive moisture. Little wind. Back to low twenties. If any time of the year there was some disease pressure it will be two weeks from now.
By the former in this case. Static is right, since the overwintered septoria YR etc was sorted at T0/1, this is the first disease pressure this season in the dry east.
T3 on Skyfall started 15 days ago here and finished on Kerrin 6 days ago.
Proline teb and pyraclostrobin on premium wheat, with epoxi substituting proline on feeders. 50% rates.
T4 unlikely but possible.
Michrodochium is my fear-cool wet weather. As soon as rain forecasted I added proline to what was (barring seed) teb/amistar. Teb good on fusarium, if well timed, little effect on michrodochium(fusarium nivale). Potassium phosphite has useful curative activity on fusariumit is also used in the turf industry to treat fusarium patch. We are pretty much right in the middle of anthesis here, 60% wheat was sprayed at first flowers GS61-everything since sunday is untreated. Mostly sundance which has a 7 for fusarium, though how accurate that is I do not know. Its head is similar to Cougar which was catastrophically poor!
Worth adding copper to any T3s not yet applied to reduce ergot?
No. Too late.
Our t3 only went on the day before the rain. 0.66 teb and 0.66 amistar. I did use a moderate dose of aviator on the seed fields. Was all just starting to flower.
Did wonder why we hadn't heard from Static for a while! is he now Teslacoils?
and dangerous, says some literature.
Copper involved in fertilisation process; chucking a quantity of biologically active Cu around at flowering runs risk of chaos (supposedly).
Yeah it's like getting sucked into a black hole and spat out in the old Farmers Weekly Forum.
So is there any point to a late T3? Only asking as in my neck of the woods, as soon as the crops started to flower, the rain started and looks to be here until next week, when flowering will be almost over
Someone said that it might protect late tillers from septoria - is there any truth in that idea?
Watch the cut off dates for fungicides. Many end at flowering.
How quickly is teb taken up? Applied to dry leaf, but steady drizzle soon afterwards which is still coming down.
Asking for a friend
As far as I know, most chemicals need at least six hours to dry properly on the leaf.
Sorry not to be more positive.
Thanks for reply, at least it was cheap!
