4种植物源农药对红花指管蚜的室内毒力测定及田间防效
Indoor toxicity measurement and field control efficacy of four plant derived pesticides on Uroleucon gobonis
摘要
Abstract
[Objective]Evaluate the indoor toxicity and field control efficacy of 4 plant derived pesticides on Uroleucon gobonis to screen for pesticides with better control effect.[Methods]Using 50%pymetrozine WG as control agent,the indoor toxicity of 4 plant derived pesticides,0.6%matrine AS,1.5%pyrethroid EW,6.0%rotenone ME,and Pinellia ternata ethanol extract to Uroleucon gobonis was determined by leaf impregnation method.The field control efficacy was determined by leaf spray.[Results]3 d after treatment,the LC50 of 0.6%matrine AS,1.5%pyrethroid EW,6.0%rotenone ME,and Pinellia ternata ethanol extract were 0.016,6.653,9.173,and 30.931 mg/L,respectively.While the LC50 of control agent 50%pymetrozine WG was 24.786 mg/L.The toxicity of 0.6%matrine AS,1.5%pyrethroid EW,and 6.0%rotenone ME were significantly higher(P<0.05)than the control.After 1 d and 7 d treatment,the field control efficacy of 0.6%matrine AS 400 times diluted solution was 76.81%and 96.39%,respectively,indicating rapid and sustained efficacy.The field control efficacy of 1.5%pyrethroid EW 150 times diluted solution and 6.0%rotenone ME 500 times diluted solution 7 d after treatment was 88.84%and 88.37%,similar to the 87.29%filed control efficacy of the control agent 50%pirimid WG 750 times diluted solution.[Conclusion]0.6%matrine AS could be used for the prevention and control of Uroleucon gobonis in the peak infection period,while 1.5%pyrethroid EW and 6.0%rotenone ME could be used in the subsequent period.All three plant derived pesticides could be promoted and applied in the prevention and control of Uroleucon gobonis.关键词
