Hazard alerts

The following alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement. These hazard alerts do not take account of usage patterns or exposure, thus do not represent risk.

Chemical structure

Isomerism	Aviglycine-HCl exhibits optical isomerism due to the presence of a chiral centre in its molecular structure. This chirality allows the molecule to exist in different enantiomeric forms. Specifically, aviglycine-HCl is known to exist in the (S)-configuration, which is the biologically active form used in plant growth regulation.

Example products using this active	ReTain Plant Growth Regulator
Formulation and application details	Usually supplied as a water soluble concentrate applied up to two weeks before harvest
Commercial production	Aviglycine-HCl is produced commercially through a microbial fermentation process using Streptomyces species, which naturally synthesise the parent compound aminoethoxyvinylglycine (AVG). After fermentation, the AVG is extracted and purified, then converted into its hydrochloride salt form to enhance stability and solubility.
Impact on climate of production and use	There is currently no publicly disclosed data quantifying the exact GHG emissions from the commercial production of aviglycine-HCl. However, since it is produced via microbial fermentation using Streptomyces species, a process generally considered more environmentally friendly than synthetic chemical manufacturing, its GHG footprint is likely to be relatively low
