Decay or ecological degradation depends on conditions. After a little web searching I found this from research in California. Aqueous photolysis half-life 43.1–2180 days (pH 7 at 25º C) Aerobic soil degradation 372 days Anaerobic soil degradation 995 days Soil photolysis half-life 173 days Field dissipation half-life 99.9-134 days
Cattle fed small amounts, accumulated low levels of diuron in fat, muscle, liver, and kidney. Little tissue storage under field conditions is anticipated (EXTOXNET, 1996).
Fish and Aquatic Invertebrates. Diuron is toxic to fish and aquatic invertebrates. The LC50 (48hr) values for diuron range from 4.3 to 42 mg/L in fish, and range from 1 to 2.5 mg/L for aquatic invertebrates. The LC50 (96hr) is 3.5 mg/L for rainbow trout (EXTOXNET, 1996). Therefore diuron is moderately toxic to fish and to aquatic invertebrates Bill thanks for the info. It’s been almost 4 yrs since he used KARMEX in his pond...... I’m not sure about the time that it takes to dissipate in pond water ( I’m a dummy)
