This research was carried out at the Research Center for Agricultural Jihad and Natural Resources center of Golestan province and Farm No. 1 of Gorgan University of Agricultural Sciences and Natural Resources in 2011 and 2012. In this research, sorghum cultivars were grown in randomized complete block design with 3 replications and 8 treatments. The pesticides used in this study are 60% Diazinon, 5% Larvin, 20% Goazitone and 40.8% Drosban, extracted fruit of bitter olive, Eucalyptus premature fruit extract, Leaf extract(Sambucus nigra), and treatment as a control. Based on the comparison of the means for different insecticides and their effect, it was observed that the Diazinon and Drsoban pesticides have a good control level and larvin and Goazitone were placed at the next levels in terms of control. Among the pesticides with natural origin, Aghty leaves((Sambucus nigra) showed the greatest effect on the extracted fruit of bitter olives and premature eucalyptus fruit extract.
