In this paper, it was shown that by application of the composition of the polyfunctional action based on dimethylolurea, phyto-connections of copper and phytoconnections of zinc as a material for preplans treatment of cotton-plant was observed in comparison with the standard reducing the incidence of plants by root rot and gommos on 10-16%, respectively increase of the preservation of plants for harvesting at 6000- 9000 pieces / ha, obtaining an additional yield of raw cotton -2.6-4.8 c/hа, the quality of cotton fiber indicators are increased by 0.3-0.6%, its length is 0.2 -0.3 mm and yield of oil 1.8-4.2%. The income form additional raw cotton is equal to 38.700-71.700 tg/ha. After harvesting in the soil, the content of easily hydrolysable nitrogen increases – 1.5-2.8 mg/kg, assimilable forms of phosphorus pentoxide – 1.3-3.7 mg/kg soil and soil organic matter – 3.6-4.8 t/ha.
