| Abstract: | Methods] A field experiment was conducted to reveal residual degradation dynamics and the final residues of hexaconazole in apple and soil,the residues of hexaconazole in apple and soil were determined by GC with ECD.Results] The degradation dynamic test results showed that the half-life of hexaconazole in soil was 7.114.4 d,and the half-life of hexaconazole in apple was 7.1-8.8 d.The final residue tests showed that hexaconazole 5% SC was sprayed for 3 to 4 times continuously at application dose 50,75 mg ... |
