Is anyone still using spinosad in California? I stopped in phase one back in November 2017. I also stopped using pyganic in Feb of 2018. I have recently started using pyganic in veg and not having any issue with it showing up in test results. I am curious if anyone has been using spinosad and if they have or not have showed negative testing results. It’s something like .02 ppm threshold ,but pyganic is .05 ppm.
My main concern is that spinosad acts systemically, but is the most effective pesticide against thrips. I will post my entire IPM tomorrow. I’m just curious if any one is using it in veg or nursery and having positive testing results.

Never have never will. i also never have bug issues or ever need pesticides. Keeping a clean grow, and people out goes a long way.

A small tent with a dozen or so plants would be very easy to keep clean.It becomes more of a task with several thousand plants , 14 employees,and all plants in composted soil organically grown. I am constantly changing my IPM and dealing with different pests in different rooms daily.It does not help that I share a building with another grow and every other building is other growers in our business park.
We are also backed up to a slough, so I am very wary of using certain pesticides. These constant battles are testing my patients so much I am questioning the whole organic thing.

@LabOwner may have something to say about this. I know @BenMGC and the @Medicinal-Genomics team or @emeraldscientific will have a responsible answer.

It was hard for me to give up ol’ reliable Spinosad/Azatrol cocktails, but now I’m managing bugs on thousands of plants using mainly environmental/access controls and predator insects. When those preventative measures fail, I typically spray emulsified oils to smother, citric acid or isopropyl solutions to dessicate, and plain water to disturb. Coverage and consistency is key; if you miss a spray day, start the regimen over.
That’s for the easy things, like thrips, aphids, and spider mites. When our neighbor harvests 80 acres of crop in a few days and all the homeless russet mites descend upon our farm, sulfur does an amazing job. Wouldn’t want to use it on a flowering plant, but fortunately our russet invasion seems to happen in mid-summer
