Transfer of the residues to the grass from the soil treated with organocholoine pesticides

The root of pasture plants were treated with additives of various concentrations of each type of pesticide (dusting power/soil, g/m²), were transplanted and grown for periods of 30 and 60 days, and the respective amounts of pesticide additives and amounts of residue present in the grass were investigated. As a result it was found that in the land which had been raised for 60 days the amount of residual products present in the grass exceeded that the grass which had been raised for 30 days. The same results was obtained for all the pesticides covered by investigation and thus one should pay sufficient care to the amount of residue present when one uses feedstaff from pasture land which has been treated in this way over a long period of time.
