摘　　要：在小麦抽穗扬花期,采用多菌灵、氟环唑等11种当前生产上推广应用的药剂,按生产防治要求分别进行2次施药,施药后检测农药残留和赤霉菌毒素情况。结果表明:除多菌灵、氟环唑、甲基硫菌灵3种农药外,其余农药降解速度都较快(2次施药后16 d基本降解完全)。多菌灵、戊唑醇、氰烯菌酯对赤霉菌毒素的抑制效果较好。In wheat flowering stage, eleven common pesticides were used in wheat production for controlling fusarium head blight. The residues and DON contents of the pesticides were detected at harvest time. The results indicated that except carbendazim, epoxiconazole and thiophonate-methyl, the degradation rates of the other pesticides were fast and residues were undetectable. Carbendazim, tebuconazole and phenamacril showed good inhibition effects on Don.
