Abstract: Deposit formation in a drip irrigation system can be prevented with a treatment composition containing from 10 to 50 % by weight hydrogen peroxide, from 1 to 5 % by weight 1-hydroxyethylidene-1,1-diphosphonic acid and up to 0.5 ppm by weight arsenic, which is added to a water stream introduced into the drip irrigation system in an amount providing a concentration of from 5 to 100 ppm by weight hydrogen peroxide and from 0.5 to 10 ppm by weight 1-hydroxyethylidene-1,1-diphosphonic acid in the water stream.
