Synergistic Effect of Aloe Essential Oil on 150 g/L Indoxacarb in the Control of Spodoptera frugiperda

PurposeTo evaluate the synergistic effect of aloe essential oil on indoxacarb in the control of Spodoptera frugiperda and provide theoretical basis for the control of S. frugiperda.

MethodsThe effect of physical properties, indoor toxicity and field control effect with adding 0.05% aloe essential oil were determined by surface tension, expanded diameter, maximum retention, indoor toxicity and field control effect.

ResultsAfter added aloe essential oil, the surface tension reduced from 51.30-67.57 mN/m to 34.43-51.60 mN/m; the expanded diameter increased from 1.33-1.98 mm to 1.69-2.93 mm; maximum retention increased from 2.86-3.25 mg/cm² to 3.34-4.65 mg/cm²; the synergistic ratio of indoor toxicity for indoxacarb to control S. frugiperda between 7.20%-19.61%, and field control effect between 3.82%-26.93%.

ConclusionThe aloe essential oil had a good synergistic effect on the control of S. frugiperda by reducing the surface tension, increasing the expanded diameter and retention.
