Hymexazol yog lub kaw lus fungicide thiab cov kev cai lij choj cog qoob loo uas muaj cov kab mob tseem ceeb ntawm ntau yam nroj tshuag. Lub permeability ntawm hymexazol tsis tsuas yog ua haujlwm tawm tsam cov av pathogens, tab sis kuj txhawb kev cog ntoo. Tsis zoo li cov fungicides, nws tuaj yeem cuam tshuam nrog hlau ions hauv cov av thiab txhim kho nws cov txiaj ntsig hauv av. Vim tias nws muaj cov nyhuv me me rau cov kab mob thiab kev ua tsis tau zoo dua li cov av pathogens, nws tsis tau cuam tshuam rau qhov chaw ecology hauv av. Nyob rau tib lub sijhawm, nws tuaj yeem decomposed rau hauv cov tebchaw nrog heev tsawg toxicity hauv av.
