I have had a red tractor non conformance for "no documented system in place to ensure statutory harvest intervals for PPP's are complied with"
What are they wanting?

A documented system in place to ensure statutory harvest intervals for PPPs are complied with.
Presumably in your spray records you need to record the HI from the label and then the date harvested. I must admit to never being asked

Thanks I have looked at various spray labels and none mention a harvest interval.

Glyphosate definitely does.

It’s obviously the question of the year, I have just been asked the same question. I use the greenlight grower software and it does appear on a report but I couldn’t find the right one.
Some chemical may not have a harvest interval on the label, check some glyphosate that should for desiccation
Don’t worry too much they will have another favourite question next year.

On many labels it is the 'latest time of application' Almost all labels will have that.

Assuming some sort of Agronomist is involved, surely your Gatekeeper recommendation sheet would state the Harvest interval for any products where necessary or the the latest date for application
Presuming this has happened, therefore you have complied.
So tell them to FO!

As far as I can tell none of the chemicals we use list a harvest interval so not sure how we comply?

Agronomist should say “by GS39 at latest” or “ before two true leaves”. On the rec sheet. And Gatekeeper automatically applies earliest harvest dates I print out a sheet with them on and stick it in the file
( double check the dates are right and comply with what’s on the labels of course)

If you don’t use Gatekeeper you could create a spreadsheet
Say what pp has been sprayed on what date, and itemise the harvest interval ( ring the manufacturer up if it’s not on the label or data sheet) and record harvest date
Make sure the dates line up !

What sprays are you using ??

Aurelia (prothioconazole))
Zonor (Tebuconozole)
These were the last sprays to be applied but how far do you need to go back.
Eg At the moment I am applying liberator what should I write in the "harvest interval first permissible harvest date box" on my pesticide application sheet?

Having now spoken to the chemical manufacturers it appears the chemicals I am using have no harvest interval so I can just write "no harvest interval" in the box.
Still not sure how to provide "documented evidence that I am ensuring harvest intervals are complied with" though?

well, they do, as they would have a latest timing. So put that when there isn't a specified number of days. Plus date of application.

By my logic if the label does not have a harvest interval anywhere, you just record the no harvest interval/ zero days. You are recording the growth stage and rate anyway. The harvest interval is the time between the application and harvest date. Technically you could spray a crop of wheat one day with a zero harvest interval product and wholecrop the next, providing all the other products applied previously for a harvest interval are complied with. Be foolish too but you get my drift. What is the definition of a harvest, combining only, crimping early, wholecropping , that is open to debate.

You are right, all this kind of information is recorded on virtually every crop protection recommendation ever made.

Don't start talking about wholecrop as that is a very very grey area that even pesticide manufacturers don't want to talk about. It's a barmy system- you can spray a crop of wheat with CMPP and then feed it to animals but you can't spray grass with CMPP just because.

Not crops but with livestock there are meat withdrawals etc, with some schemes like organic the withdrawal’s are doubled (used to be trebled) although I’m treating with something this autumn I still need to put the meat withdrawal on my record sheets. Anything which has no withdrawal gets 7 days just to be safe 
It may be obvious with just cereals but if you grow veg/potatoes/salad etc you could be harvesting most of the year so harvest intervals are key - especially when insecticides are used on veg and salads etc

Every recommendation would include indicated harvest intervals where one existed. This would be automatically populated by the software in question. The same systems have all kinds of reminders and limitations included regarding crop growth stages and the like.
