I know everyone is trying to be helpful. I do not think "Start with pesticide free trim" is that helpful. Does anyone have a process that reduces pesticides in concentrates to OR standards including Myclo? Thanks
Uh, didn't you read the thread?
NO, you can't fix this on the back end, that's why " Start with pesticide-free material" is the best and ONLY answer. Whatever it takes too achieve this is the only correct course of action. There is no "pro" trick for making good on contaminated concentrates, STOP believing there is.
Sooner than later people are going to lose their sense of humor about all this and some of the "I can fix this" crowd are going to go to jail.
Good question! Let me check with a CO2 guru and I'll report back.Hey Graywolf, when you point out the contamination of recovered butane. Would it also apply to CO2 contamination as well if pesticides were present?
That's awesome and thank you.Good question! Let me check with a CO2 guru and I'll report back.
My SCFE CO2 resource says that he understands that some pesticides do come across using CO2, though he hasn't run confirming experiments.That's awesome and thank you.
I'm interested in discussing this. GreenWitchThis is a very common issue here in California. We have been experimenting for years trying to remove pesticides from trim sourced for our facility. Initial tests will come back clean and extracts test dirty. To take that one step further trim tests clean, sugar or wax test clean and then distillate tests dirty. The problem is Myclobutanil and Neonicotinoids have a very similar molecular shape, weight and size as thc and other cannibinoids. Turning it into clear will only increase your ppm of these pesticides because you will be removing other compounds like lipids and fats thus increasing your ppm of residual pesticides. Private message me and I'll tell you what we are doing to remove as much as we can but I haven't been able to move 100% of them.
co distillation techniques and some extra filtering to grab what you can i've only seen it go down to ppb never completely removed but ppb better then the ppm i've seen everyone else struggle to get to but 0 is def the goal...Work for a prop 215 company in north cali. had some oil test positive for p. seeing esticide. Has myclobutanil in it 2.40mg/kg. Looking to see if anyone has ideas. I was thinking a hexane wash looks like it is soluble in water.
I'm not just saying this without a reason let me explain. If you live in CA then you know that we grow grapes.... a lot of grapes.
Okay... Everyone saying (Throw it away only use clean material) you're a bunch of impractical idiots, and I'm not just saying this without a reason let me explain. If you live in CA then you know that we grow grapes.... a lot of grapes. Myclobutanil is predominately used in CA, I mean like 90% or so of the Myclobutanil is used here in CA, pretty much the only other place it is used is France. Its used to control PM on grapes and is sprayed by atomizers or dumped from aircraft over vines to get onto the plant. It travels literally 100's of miles in the air and if you grow out doors pretty much anywhere in CA then you have it. You have it in low or high doses which is why it comes up so often. People know not to use Eagle 20 but it still comes up in an outdoor field.
Graywolf, Ive followed you for years I mean nearly a decade man and this is hands down the weakest chain of responses I've ever seen from you, as a matter of fact it was so poor that I made an account so I could post this. You almost always have an answer to every problem or at the very least can point someone in the right direction. I have the upmost respect for you by the way.
Pesticide removal is the right way to go. Medicine can still be safe if the pesticides are low reduced below detection which in most cases is between .1-.2ppm. You take in 10x more pesticide eating an apple. Hexane washing is on the right path, most of these pesticides are virtually insoluble in saturated Aliphatic hydrocarbon, but you still have to filter it out so you need to use size exclusion to remove them. a 15 micron filter will probably get you below detection.
The other option is saponification, most of these pesticides undergo hydrolysis under highly alkaline PH. Let it sit for 8-10 hours at a high ph preferably 10-12 and then mix thoroughly, make sure to rebalance or when you begin to take off your solvent you'll make soap. hope this helps people out.
