Univoq / Iconiq drip stop issues?

[Hammer]

I sprayed Univoq on Tuesday and Wednesday. No mix other than manganese. Noticed a few nozzles slow to open. Washed out on Wednesday after finishing. Ran some fresh water through the sprayer yesterday and loads of nozzle valve diaphragms had gone so replaced all 60. And then this morning the Ramsey valve diaphragms went too. So it seems the damage may take a few days to show itself.

Reports of T2 spray damaging sprayer components - Farmers Weekly

Several incidences of the degradation of sprayer components have been reported in the UK over the past week, where the tank mix applied has included the

Looks like this could be a take pics; keep receipts job.

Revystar was the dogs bo!!ocks last year, chemistry doesn't last long these days it seems!

I prefer not being an early adopter!

Revystar for me this year.

Sprayed on alright. No perceivable damage.

Just ordered nozzle diaphragms from bateman due to many leaking, bits of rubber have eroded away allowing pin pr*ck holes , bit concerned about other components.

Sprayed Questar Wednesday/Thursday this week. Had 3 blocked nozzles but didn't think much of it at the time. Had a closer look at the nozzles today and at least 12 were partially blocked with little bits of rubber. Very annoying to have a compromised spray pattern on one of the most important/expensive spray applications of the year. Looks like some pipe sealant that has been dissolved. Also found several little plastic tabs in the primary filter which came off the spray can handles and fell into the induction bowl. The incredibly strong solvent smell it gives off is also terrible PR when spraying near the public. Won't be using again, shame as it looks like the best product on septoria.

Breezy now so have rinsed out the sprayer for tomorrow. No issues visible yet, but Ive got a diabolical headache. Cant remember feeling as awful after half a days spraying since we stopped using dimethoate.

I used some Priaxor and that stuff stinks and has made me feel rough.

We have used batch APR22CEO22, 21 & 24

We'll wait and see what trouble we get.

Used last Saturday , first time . Could nt understand why I had 9 diaphragms fail in 60 ha but thought at time that as machine is 2 and half years old , must be their time is up . Have now seen this thread and now see the connection. Did another 80 ha yesterday but no issues but did luckly go on and do a round up job after so its had a wash out . To be fair , it's only original diaphams failing , ones I have replaced before seem ok .
Agree it stinks of solvent.

I got a head ache too. i never get them probably had a handful all my life.

I thought the actual concentrate smelt quite nice. But the headache was bad, and I've somehow got some on my skin perhaps from when I got out to set the sirayer to rinse out and I've two patches of eczema on my elbows flare up and where the skin on my neck is I've clearly touched with my hands and it bloomin angry. Chem is nasty stuff in general but I think if I use this again I'll be taking more than the usual care.

 

[teslacoils]

I'll not put a pic up but my neck looks like I've got sunburn! Anyway, if you get a blocked nozzle etc don't forget your PPE!

I used 25 well that’s on the 2 cans I have left over (all other cans have been diposed of) and it f**ked 20 of my airstops

We used it last year and this year and have not seen any problems, that I know of anyway. Fingers crossed.

Yellow rust 9
Brown rust 5
Septoria 6, 5.8
Last time it appeared on recommended list 2 years ago.
What disappoints me is my Elatus Era which we had in stock was taken away on Wednesday and replaced with Univoq on Thursday. At the time I wasn’t aware of sprayer issues and thought it must have been swapped for sound agronomic reasons. Maybe it was. But I’m feeling a bit angry about it. I am just doing a bit of asking on here before completely losing my rag, or not.

Who swaps your chemical without consulting you?

 

[robbie]

It makes you wonder about these new chemicals, last year it was all about the disappointing results from revystar along with operators complaining of feeling unwell after using it and this year we've got univoq eating the insides of sprayers and again reports of operators feeling rough after using it.

I'll stick with being unfashionable and using ascra!!!!

 

[Hindsight]

Oh for Opus + Bravo!

 

[Hard Graft]

What was the Scientific reason for Bravo ctl to be removed
Also worried as used univoq as well and it now makes sense the couple drip stops I have had go too
