Title : | TOLERANCE OF BLACK LOCUST (Robinia pseudoacacia L.) SEEDLINGS TO PRE APPLIED HERBICIDES |
Abstract : | The field studies were conducted in the nursery of the PE "Macedonian Forests", subsidiary "Karadžica" in Dračevo, Skopje region, during 2014 and 2015 on Fluvisol sandy loam. Tolerance of black locust seedlings to the PRE application of imazethapyr, S-metolachlor, linuron and pendimethalin was studied. The black locust seedlings differed in their response to PRE herbicides. All applied PRE herbicides caused no significant visual injury (< 0.7%) in black locust seedlings in 2014, but linuron and pendimethalin applied in 2015 caused serious black locust seedlings injury which did not decrease over time (48.5% and 60.5% at 28 DAT, and 63.8% and 72.3% at 56 DAT, respectively). The high precipitation which occurred immediately after herbicide application (28 L/m2) probably was the most likely reason for serious black locust injury caused by these herbicides. PRE application of herbicides in 2014 resulted in statistically similar plant number per m2, plant height and root collar diameter to the weed-free control. However, all black locust seedlings parameters were significantly affected by linuron and pendimethalin in 2015. Their application resulted in fewer plants per m2, minor plant height and smaller root collar diameter of black locust seedlings in compare with those in weed-free control |
