A reassessment of hazard classifications for tebuconazole and propiconazole
We are reassessing the classifications of two fungicides.
Hearing or consideration
Tebuconazole and propiconazole are active ingredients used as fungicides. Both substances are used as timber treatments, and as pesticides across a range of cereals (barley, wheat, oat, rye, corn, triticale), pasture, ryegrass, pome and stone fruit, olives, kiwifruit, grapes, onions, avocado, peas, turf and ornamental plants.
Why are we reassessing these chemicals
We have identified significant new information for tebuconazole and propiconazole. It suggests their hazard classifications need updating.
We identified new information for tebuconazole in our 2019 assessment of Scorpio (APP203305), where the applicant provided studies on reproductive toxicity.
Separately, an EU non-renewal decision for propiconazole reported adverse health effects on the reproductive system. EPA scientists raised other classification changes, alongside further classification reviews by overseas regulators.
Background to the reassessment
We established grounds for reassessment in April 2021, based on new information about tebuconazole and propiconazole.
Latest application update
26 January 2022 – timeframe extension for consideration date
