Glyphosate Free Yellow Peas Rejected

3 parts per billion is a crazy small amount. What is the plus/minus error bar on their testing procedure?

You guys will all remember the Triffid issue in flax. They were using coffee grinders to grind flax to test. """Do you sterilize them after every grind between samples?""' I asked as I watch them do it. No. Then how can it be a certified test when you are talking such small amounts?

Idiotic the whole thing.

3 parts per billion is a crazy small amount. What is the plus/minus error bar on their testing procedure?

+- .007 ppm or 7 pp billion.

[ColevilleH2S]

+- .007 ppm or 7 pp billion.

So what's their problem? 0.013 ppm is well within/under their error probable of 0.003 to 0.017 ppm

[Grahamp]

Parts per billion testing is very bad for agriculture. They’ll be able to reject anything if the price goes against the buyer.

[Dr Tone]

So what's their problem? 0.013 ppm is well within/under their error probable of 0.003 to 0.017 ppm

That’s the 3rd party lab margin of error number. It’s all just games. I’ve learned my lesson, and hope this thread helps others .

Preseed burn off can cause this much residue, we had a study done on our production a couple years ago.

What rate did you apply in burnoff.

[dave4441]

It's not necessarily the burn off that's the issue and it's not drift. It's trace levels in rainfall/environment.

Noone would try and blend these levels and the buyer will be just as disappointed as the seller when the test comes back positive.

Organic exporters are having the same issue.

And it can change from the bin sample to loading into railcar. At these levels it's difficult to meet.

The bigger the crop the less chance there is of residue showing up. I believe it's due to dilution but it's a wild ass guess.

Destination buyers (mainly China) won't negotiate on levels as their buyers demand the level. It's a good market if you can hit it but it takes a level of luck to meet the spec.

[BreadWinner]

We applied 1 liter per acre pre burn and there was a detectable level and the ground we did late fall spraying had no residue. The plants picked up a small amount of residue during emergence.

[Dr Tone]

Noone would try and blend these levels and the buyer will be just as disappointed as the seller when the test comes back positive.

One of our bins is 60% the field that passed and 40% the field that didn't. They want a sample of that bin now, so blending apparently isn't an issue for them.

Fields are a couple miles apart, both pre-burn .67 L/ac and both yielded well.
