The problem of weed infestation in conditions of applying the growth bioregulators and foliar fertilization in potato cultivation
Abstract.

The field experiment was carried out in Parczew in the mid-eastern part of Poland in the 2001-2003 years. It was set up in a split-block design, with the following experimental factors: A – potato cultivars ‘Bila’, ‘Glada’, ‘Danusia’, ‘Ania’, B – treatments of a biostimulator or/and foliar fertiliser: Asahi SL, Insol 7, Asahi SL + Insol 7 and control. The preparations were applied at doses recommended by producers. Application of growth regulator Asahi SL increased growth of fresh and dry weight of weeds, both before closing rows, and before harvest, compared with the control. Preparation Insol 7 limited fresh and dry mass of weeds, but only to the row closeness, while before harvest contributed to the growth of a secondary infestation. Combined use of agrochemicals was conducive to maintaining a greater abundance of weeds monocotyledons, mainly Echinochloa crus-galli, and reduces the number of dicotyledonous weeds, through the elimination of Chenopodium album.
