Sucking pests are noxious agents at early season. In corn cultivation. In addition to direct damage these pests can transfer many viruses and bacteria. Using of pesticides not only have low efficacy but increase production expenses. Therefore application of insecticides as seed treatment can be an improvement in the methods and optimizing the chemical application. In this research efficacy and stability of imdachlopride (Gaucho) on early season sucking pests of corn were evaluated under field condition comparing to common pesticides. The selected field had a background of corn cultivation and contamination to sucking pests like leafhoppers aphides and thripses. This project were performed in two 1 hectare treatments in Chagha-Narges, Kermanshah country. The treatments included Imidachlopride (Ghacho) on seed treatment (6 mg/kg). the spraying in control treatment was carried out with Dimethon methyle (Mettasistox) as 1.5 lit/hec. Scoring were done every 7 days during 6 weeks. Pests density and percent and plant contamination were investigated and the results were included in related tables. After data analysis the results indicated that there was significant difference at 1% level and for the yield it was significant at 5% probability. Total conclusion showed that in Gacucho treatment the damage was lower and yield was higher than common insecticide.
