Biological target:
MCPA-thioethyl is a biochemical.
In vitro activity:
The presence of MCPA significantly reduced sorption and increased desorption of glyphosate, but only when MCPA was present at concentrations much greater than environmentally relevant and there was no phosphate added to the MCPA solution. Reference: J Environ Sci Health B. 2017 Dec 2;52(12):887-895. https://pubmed.ncbi.nlm.nih.gov/28961057/
In vivo activity:
The presence of the MCPA-PHBV conjugate in the biodegradable PBTA/PLA blend was shown to completely suppress the growth of broadleaf weed species while displaying only a mild effect on the growth of the model crop. Reference: Biomacromolecules. 2018 Feb 12;19(2):511-520. https://pubmed.ncbi.nlm.nih.gov/29261293/
