Field experiments were carried out to investigate the dissipation of boscalid in strawberries and soils and its residual levels in strawberries at two different sites. Boscalid (50% water dispersible granule) was applied at two dosages (349.5 and 525.0 g a.i./ha). Soils and strawberry samples were collected at 0, 1, 2, 3, 5, 7, 14, 21 days after application of boscalid. The results showed that boscalid dissipation pattern followed the first order kinetics with the half-lives of 4.9 and 6.4 days in strawberries and 6.1 and 8.0 days in the soils of Jinan and Beijing trail sites, respectively. The boscalid residues in strawberries were below the EU maximum residue level (5 mg/kg) after three days of application. This study suggests that boscalid is acceptable to apply for strawberries under the recommended dosage.
开展田间试验研究了啶酰菌胺在草莓和土壤中的消解动态及其在草莓中的残留水平。啶酰菌胺（50%可湿性粒剂）以两种剂量（349.5 和 525.0 g a.i./ha）施药。施药后 0、1、2、3、5、7、14、21 天分别采集土壤和草莓样品。结果表明，啶酰菌胺在草莓和济南、北京两地土壤中的消解符合一级动力学方程，半衰期分别为 4.9 和 6.4 天、6.1 和 8.0 天。施药 3 天后，草莓中的啶酰菌胺残留量均低于欧盟最大残留限量（5 mg/kg）。本研究表明，啶酰菌胺在推荐剂量下使用对草莓是安全的。
