Sugar beet has a lot of pests and diseases, which some of the pests invade the young plants, in the early of the season and make serious damages. Seed treatment is one of the methods to preserve young plant, against the pests that feed from plants early season. To date, the insecticides that are formulated internally can be as suitable alternative for foreign formulated. In this regard, the study of the efficacy of the internal formulated insecticides compared to the foreign formulated for seed treatment of sugar beet was investigated. The seeds were selected from a internal cultivar (Paya) that are widely grown. Four treatments, including three insecticides, Imidocloprid (one percent), its internal formulation (Danposh)) (1%), thiamethoxam (1%) along with control (without seed treatment) were compared, in five replications and in a completely randomized block design. Each plot consisted of six lines of five meters of sugar beet plantation that were about 15 centimeters apart from each other. The plots and the blocks were one and two meters apart from each other, respectively, This study was carried out in two provinces, Kermanshah and Alborz, The number of Leafhopper on the plants and the percentage of the infected plants with curly top virus were analyzed by ANOVA test using the SAS program. The results showed that Kermanshah province, and in the first two weeks of survey, the internal formulated (with 59.58 and 83.21, respectively) had a good performances compared to the foreign formulated (with 50.00 and 77.39% respectively). While the insecticides performances in Alborz province, for the internal formulated (47.91 and 25.91 respectively) and for external formulated (50.63 and 36.44, respectively), were recorded. Therefore, internal formulation can be used for seed treatments of sugar beet.
