A cautionary tail on Spinosad

I tested the bud that was 4 weeks into flower when we last sprayed and it showed residual spinosad as well, so into the worm bin it goes. Two more weeks and we'll test the last of the flower that was in the room when we sprayed. It was at 2 weeks during the last spray

Do you know the ppm that it came back at?

We had some spider mites about 3 months ago that were hard to get rid of. We are a fully organic grow and only use omri listed insecticides. I used spinosad sprayer 3 weeks into flower and it worked well. Spider mites disappeared and haven’t been back.
Unfortunately we tested that flower this week and both cultivars failed pesticide testing for spinosad. I didn’t actually realize spinosad would be tested for but I’m not sure that would have made a difference. I really didn’t think 3 weeks into flower would still be around at harvest, and I guess I let the “organic” label lull me into a sense if security.
I’m not saying don’t use spinosad, but if you have to pass regulatory testing, I would advise caution

I see "Organic" or OMRI and I instantly trust it too. Despite this:

I did pest elimination (not control) for a season - the absolute most lethal chemicals onboard my vehicle were all organic.
Full Tyvek suit and Organic VOC cartridges on the full face respirator type of lethal.

Most have a half-life of 20-60 days or so.

Synthetics were usually milder toxins, but had longer half lives - up to 6 months.

Perfect example - Chrysanthemums
Pyrethrin based insecticides - liquid and fog applications (Permethrins (sp?) are the synthetic version)
Another use for this flower is a form a tear gas.

As much as I value the advice I receive here, I make sure to do my due diligence before applying anything to plants I'm planning to consume in a month or two.
