The snail investigation was carried out in the irrigation system areas and the results were compared between the study area and the control area. Results The snails were discovered in the floats of riverhead of the electric pumping station. However, there were no any snails in the exit of pump after the block snail treatment and no any snails in the irrigation areas, either.
