| Abstract: | The research aimed to assess residues dynamics of mandipropamid in Litchi and establish guideline for safety application.Field trail for mandipropamid residue in Litchi were conducted in Nanning and Haikou.The results showed that the half-life of degradation for mandipropamid was 6.2～7.3 d in Litchi,6.6～10.1 d in soil.The final residues quantity were no detection～0.055 mg·kg-1 in Litchi samples,no detection~0.015 mg·kg-1 in Litchi flesh samples,no detection～0.124 mg·kg-1 in Litchi peel samples when the last spraying mandipropamid after 3,7,10 days.The reasonable use technology was sprayed 3 times with 125～250 mg·kg-1 of mandipropamid,the preharvest interval was 3 days,the maximum residue limit was recommended 0.5 mg·kg-1. |
