Abstract
Considering the necessity of omission of monocrotophos from tobacco budworm, Helicoverpa armigera, control program, tests were carried out to assess the effect of indoxacarb, as an alternative in years 2005-2006. The experiments were conducted at randomized complete block design, using indoxacarb (Avant SC 15%) at rates ranging 200, 250, and 300 ml/ha, and conventional insecticides thiodicarb (Larvin DF 80%) at rate of
1 kg/ha and monocrotophos (Nuvacron SL 40%) at rate of 2 l/ha. Percent mortality was calculated using Henderson-Tilton formula at 1 and 3 days after spraying. A repeated-measures analysis, general linear model (GLM), indicated a significant difference among treatments for percent mortality of budworm. Both indoxacarb and thiodicarb caused a high mortality of the larvae, whereas monocrotophos revealed the lowest effect. In general, Avant SC 15% at the rates between 200 and 250 ml/ha is recommended for controlling tobacco budworm
