Dysect , does it protect well against fly strike

[Norfolk Hill Farmer]

Had the sheep sheared for a couple of weeks now, and starting to think about covering them for fly strike. I know Click Extra will do the job , but is becoming very expensive.
What are other people's experience with Dysect pour on ? I know it doesn't last as long as CE but is much cheaper. Toying with the idea of not treating them until the end of July with Dysect, and hopefully ,this would cover them for the rest of season. Do people think Dysect is as good as Click Extra,all be it for a reduced time? Also does it spread round the whole body to protect every where, not just the direct areas it is applied to ? Some say it does, some say it doesn't. I'm sure the TFF members will give me the definitive answer

TIA NHF

Dysect is probaly the best alternative to click as its very repellent will be good for 8 weeks , BUT its horrible stuff to use (dont get it on your skin ) always wear protection and in well a ventilated space , and you get left with black mark where its applied , works brilliant though ,downland do a cheaper generic called zermasect , I use downland crovect generic, vectocert .

We use dysect on the ewes 7weeks before shearing for peace of mind. Always works. Just shorn them last Saturday and not a maggot. It has lasted 11 weeks on full fleeced ewes. Think it is 12 or 14 weeks protection. It works and does spread around the body. Don't get any on your leggings as it just eats into them.

Do you have a reason for using a Crovect type product instead of a Dysect type product ?

The active ingredient for both is cypemethrin.

Dysect is Alphacypermetherin.

Dysect is Alphacypermetherin.

There doesn't seem to be much difference in the two - the toxicity for both is pretty similar. http://www.inchem.org/documents/jecfa/jecmono/v53je05.htm

IME, Dysect lasts much longer than Crovect and it's generic counterparts (Ectofly and Zermasect). It also spreads out from where you put it (applied with a dribble bar). Crovect only protects the bit that got sprayed (applied with a fan nozzle).

A lot longer withdrawal period with Dysect than Crovect too.

The only drawback with Dysect is it's 'oily' and the fleece gets stained with dust that sticks to it. Our hoggs and their lambs are grazing a spring sown ley on very light land (you can still see the drill rows) and they look filthy with all the sand they've picked up - not got any flies on 'em though

yes i sell breeding sheep and i dont want a dirty line down back , nicer to use , IF click was double price i would only use that but nearly 3 times is taking the mickey for double alternative cover . Should a generic copy emerge will only be click type spray

Dysect is, IMO/IME the best fly/parasite prevention pour-on product on the market.


BUT it has its drawbacks;

It is a wee bit savage - as @andybk says, it leaves dark marks on wool and at worst almost singes the wool on poorer doing stock.

The withdrawal period is very long at 49 days.


Both things needed taken into consideration when using the product. Especially on lambs.

Doesn't seem much different...

yet Crovect cover 6-8weeks for blowfly when Dysect will do 8-10 weeks cover at the same 40ml dose rate.

8 day withdrawal compared to 49 tells a different story, too.

I wonder if the difference is in the viscosity, if they are both similarly toxic to invertebrates.
Dysect may take longer to wash off.

Can you not get them dipped?

 

[andybk]

a few years back i sprayed a ewes back with dysect during a thundery spell , and there were some pestering green bottles about one landed on the fresh dysect and just fell off the back of the ewe dead . we did use it a lot during the bluetounge days as i think it had good repellent properties for midges

 

[Man_in_black]

Brilliant stuff, imo without doubt the best product at doing its job, it spreads throughout fleece like clik but also with the benefit it can be used to treat as well as prevent.

But as has been said, don't get it on skin; twice (should have learnt after 1st) I've got a good amount on bare skin & I felt nauseous, dizzy, hot & sweaty just basically shiťţy.

Probably could, was hoping to draw a few fat lambs from them. Not sure if this would be practical while they where rearing lambs. Open to suggestions on ways to do this though. Would be concerned the dip would rub from the ewes onto the lambs making withdrawal time issues.

If the ewes are separated from the lambs before the Dysect is applied ,then allowed to stand for a short period , can the lambs get stained by brushing against there mothers. Is this a thing ? all being well a lot will go as stores in August, so don't want them with black Stanes on them.

I was spraying lambs on Saturday with Vectocert, up the side of a pine shelter strip. Flies galore!!


It's quite satisfying 'shooting' flies as you spray the lambs, and seeing them drop dead instantly

Ahh is it the ewes you want to do?? (I thought you'd be spraying the lambs).

It's a T bar you use for Dysect. Separate them if you want but I'd just do them mixed. Your lambs will be fine with a bit rub on them

Yes it's the ewes I want to do. The lambs have already been done with click extra, so they should last the season. The ewes are now getting some regrowth after shearing but if I dare leave them for another 2 or 3 weeks and then do them with Dysect ,they will go on through the season as well. Although I have had sheep fly struck well into October before.

You'll be grand. You said you'll sell lambs as store, just keep yourself in the clear and work out the end of retention from the day you spray the ewes and declare it at sale
