In this research the effect of Bacillus thuringiensis, Carbaryl and Diflubenzuronindependently and different combinations of them were tested against Helithis viriplaca HuFn. in laboratory conditions. In order to conduct bioassay experiments, the pupa were collected from the field and reared under controlled conditions. Third larval stage was used for bioassay experiments. In bioassay experiments the best concentration of compounds were selected individually and in combination using randomized block design. The laboratory tests showed that Bt with concentration of 2600 ppm and 1900 ppm revealed the best result and Carbaryl with concentration of 1900 ppm and Bt with concentration 1600 ppm were in the second rank. The comparison of tested compounds individually and in combination showed that mixture of Carbaryl-Diflubenzuron-Bt, Carbaryl-Bt, and Diflubenzuron-Bt were better than other treatments (p≤ 0.01) and Crarbaryl and Diflubenzuron mixture had least effect with no statistical difference with Bt effect.
