We were doing a test run on some new concentrates (high cbd hemp). We ran a pesticide test and came up with azoxystrobin as a fail at 437ppm with a threshold of 200ppm and a non fail but a show up for spynosin but at very low levels and no fails.
After looking into the failed pesticide and speaking with the growers it was determined that none of the listed fungicide that have azoxystrobin in them were used.
The only listed fungicide they used in the grow was copper sulfate and lost coast plant therapy to prevent mold and botritis.
It could have been drift somehow? These can both be found in soil and foliar applied fungicide brands.
We have only ever had 2 test in 4 yrs come back for failing fungicides when extracting for clients. And the other time it was determined to be drift from a neighboring farm.
Never the less it is there and we are wanting to know if it can be cleaned out of the product. Any help or knowledge is appreciated and I will read and evaluate each response. Thanks future 4200 community!!
