摘要

[Objective]The paper was to study control effects of 12 kinds of insecticides on sugarcane pests at different periods.[Method]By field experiment,the control effects of different insecticides against sugarcane pests at planting stage,seedling stage and tillering stage of sugarcane were studied.[Result]After seedcane was treated by Chlorantraniliprole,Durivo and Seed soaking,the dead heart seedlings were significantly reduced in fields,and the control effects were87.13%±12.87%,85.22%±14.78%,82.71%±17.29%,respectively;Durivo(seedling emergence rate is 63.00%±10.30%)and Seed soaking(seedling emergence rate is 57.75%±4.50%)could also significantly enhance seedling emergence rate.After"removal-irrigation"treatment during seedling stage,the control effects of Flubendiamide(76.26%±4.31%)and Chlorantraniliprole(61.66%±6.65%)against sugarcane stem borer were significantly higher than Virtako(60.17%±7.06%),Deltamethrin(38.75%±9.88%),lambda-cyhalothrin(54.06%±6.83%),18%Dimehypo AS(37.98%±10.31%)and Dipterex(38.64%±9.34%).During tillering stage,with the increased application of 3.6%Dimehypo GR in cultivation and earthing up,the control effect on stem borer was significantly increased,and the control effect reached(72.03%±17.06%)as the dosage was 120 kg/hm2;when the dosage of phoxim exceeded 30 kg/hm2,the control effect on underground pests reached 44.00%±14.80%,and the control effect did not have significant difference as the dosage was ranged from 30kg/hm2to 60 kg/hm2.[Conclusion]The paper provided scientific basis for selection of different control methods,different chemicals and dosages against pests during different periods.
