The aim of the present study was to test the influence of two rates of a. i. oxyfluorfen (Goal 2 E) on the weed control and growth of fruit-bearing apples trees. The following variants were set: a1 – control (untreated); a2 – oxyfluorfen (Goal 2 E in rate 250 ml/ da); a3 - oxyfluorfen (Goal 2 E in rate 500 ml/ da). The number and the weight of weeds were reported on 30th, 60th and 90th day after treatment. The indexes for annual shoot length increment and stem cross section area were studied after the end of vegetation. The obtained results showed that oxyfluorfen had a three-mounth weed control efficacy. Only weed species unsusceptible to oxyfluorfen were present. A depressing effect on the tree growth expressed by the annual shoot length and stem cross section was not detected.
