Research on Risk of Carbendazim Residue by Different Application Methods in Wheat Earing Stage

The carbendazim residues of different application frequency, time and dosage were determinated, the risk of carbendazim residues exceeded maximum residue limit was analysed. The results showed that the risk of carbendazim residues exceeded maximum residue limit was closely related with the application frequency and dosage. The risk of carbendazim residues exceeded maximum residue limit increased with the increase of application times and application dosages.
