Dissipation kinetics of diclosulam 84% WG @ 1.0 and 2.0 μg mL−1 active ingredient in water at pH 4.0, 7.0 and 9.2 is reported. Water samples collected on 0 (2h after application), 3, 7, 15, 30, 60 and 90 days after treatments were processed for diclosulam residues by HPLC. The calculated half-life in different water samples showed its stability to be lowest at alkaline pH (9.62–10.67 days) as compared to neutral (64.05–70.01 days) or acidic pH (75.26–79.22 days), irrespective of the dose.
