We determined TFA formation from seven C\u2013CF\n                    <jats:sub>3<\/jats:sub>\n                    pesticides with high sales rates (trifluralin, fluazifop\u2010P\u2010butyl, fluazinam, tau\u2010fluvalinate, diflufenican, fluopyram, and mefentrifluconazole) over 52\u00a0weeks in a laboratory experiment with three agricultural soils. TFA was formed from all seven pesticides, but TFA formation varied both among compounds and among soils. Fluopyram had the highest TFA formation, at 10.7% of the pesticide amount added in one soil, but lower formation in the two other soils (3.3% and 7.9%). Fluazinam also had relatively high TFA formation (5.3%\u20136.5%), but unlike fluopyram, only minor differences were seen between soils. TFA formation was lower for the other pesticides with 2.4%\u20135.2% for diflufenican, 3.0%\u20135.3% for fluazifop\u2010P\u2010butyl, 1.1%\u20132.2% for trifluralin, 0.8%\u20133.3% for mefentrifluconazole, and 0.4%\u20131.0% for tau\u2010fluvalinate.
