Wheat-root scale has incurred losses in certain parts of Kordestan province. In a two year research project, applied as follows: A. Experiment on effects of toxins in the tillering stage of the wheat crop. B. Experiments on effects of agricultural processes were carried out, in rain-fed farms. The 1993 surveys showed that the infection percentage was high in the fourth attendance and considerably so in comparison with other attendance periods in the same group. Thus, it was concluded that all sound agricultural processes including the inhibition of wheat-grain full-off during the harvesting period, rotation and timely spring ploughing in the rotated farms in order to exclude single wheat stalles and weeds playing host to pests, and thus destroying their nutrition resources, were, in combination, the most effecient method to control and diminish pest populations and hinder the resulting losses over which peticide application as an alternative is not recommended
