- 摘要:
- 以龄幼虫为研究对象,采用胃毒触杀联合毒力法,研究2种农药助剂(两份保和减维康)与减量辛硫磷乳油(EC)混用对韭菜韭蛆的防治效果。结果表明:减少30%~40%辛硫磷用量、加入实际用药量14%的两份保、减维康对韭蛆3龄幼虫的LC50 值分别为1.74~2.01 mg/L、1.96~2.28 mg/L,与40%辛硫磷EC的毒力(1.84 mg/L)相近。
- Abstract:
- Taking 3-year-old larvae of Bradysia odoriphaga as research object,the toxicity determination of the mixture that less Phoxim than conventional dosage mixed with pesticide adjuvant (Liangfenbao and Jianweikang) in controlling Bradysia odoriphaga Yang et Zhang was determined by stomach-contact combination toxicity method in the laboratory.The results showed that the LC50 values of the mixture(containing 14% of Liangfeibao or Jianweikang and 30%-40% less Phoxim than conventional dosage)in against three-year-old carvae of Bradysia odoriphaga Yang et Zhang were 1.74-2.01 mg/L,1.96-2.28 mg/L,respectively.The toxicity was corresponded to the conventional dosage of Phoxim (1.84 mg/L).
