Summary: The 75–80% viability of Eupatorium odoratum seeds was found to be affected by the temperature of the environment where they were stored. The loss of viability increased with longer periods of storage. Seeds stored under — 10°C or 8°C still retained their viability after 26 months, those stored under 27.5°C or 37°C lost their viability during the same period. There was a gradual loss of viability of herbicide‐treated seeds stored under — 10°C or 8°C. The rate of loss was greater for herbicide‐treated seeds stored under 27.5°C and 37°C and eventually led to the complete loss of viability after a short storage period of up to 13 months. EPTC and molinate had the greatest effects on seed viability.
