摘要
为了寻找田间防治柑橘木虱(Diaphorina citri)的新方法,在脐橙上开展浇施噻虫嗪防控柑橘木虱试验.结果表明:4 月中下旬浇施 1 次 25%噻虫嗪水分散粒剂 1 500 倍液(施药量 0.17 g/m2)可有效控制柑橘木虱 1.5～3.0 个月;25%噻虫嗪水分散粒剂 1 500 倍液浇施脐橙树 28d后,脐橙果实的噻虫嗪含量为0.06 mg/kg,远低于《食品安全国家标准 食品中农药最大残留限量》(GB 2763-2021)规定的噻虫嗪在柑橘类水果中最大残留限量(0.5 mg/kg)的标准,在采收前 1 个月浇施 25%噻虫嗪水分散粒剂 1 500 倍液防治柑橘木虱是安全的.
Abstract
In order to find a new method to control Diaphorina citriin the field,the experiment of controlling Diaphorina citriwith thiamethoxam was carried out on navel orange.The result showed that in mid-to-late April the control effect of single pouring 25%thiamethoxam water dispersing granule 1 500 times(the dose was 0.17 g/m2)could be as long as from 1.5 to 3.0 months in field.The pesticide residue of thiamethoxam in navel orange was 0.06 mg/kg after 28 days of applying 25%thiamethoxam water dispersing granule 1 500 times.It was far lower than the 0.5 mg/kg maximum residue limit(MRL)of thiamethoxam in citrus fruits stipulated in the national standard for food safety(GB 2763-2021).It is safe to apply 25%thiamethoxam water dispersing granule 1 500 times 1 month before harvest to control Diaphorina citri.
