Efficacy of bentazone and dicamba combination in controlling weeds in wheat

Abstract

The objective of this investigation was to determine the efficacy of CAMBIO (320 g/L bentazone + 90 g/L dicamba) in controlling weeds in wheat. The trials were conducted on two localities at Zemun Polje and Smederevska Palanka in 2000. Both efficacy and phytotoxicity were assessed according to standard EPPO methods. The application rate of CAMBIO was 1 L/ha. The control herbicide was Duplosan KV (mecoprop), applied at a rate of 2 L/ha. Before the application of herbicides, an assessment of species was performed according to Brown-Blanquet, and the following weed species were determined as dominant: Bilderdykia convolvulus L, Myagrum perfoliatum L, Polygonum lapathifolium L, Stachys annua L, Veronica hederifolia L (in Zemun Polje), and Consolida regalis L, Fumaria officinalis L, Lamium purpureum L, Matricaria chamomilla L, Polygonum aviculare L, Sinapis arvensis L, Stellaria media (L.) Vitt., Stachys annua L, and Xanthiu strumarium L. (in Smederevska Palanka). The efficacy of CAMBIO, based on weed numbers and fresh weight, was determined twice: 15 and 45 days after application. CAMBIO showed excellent efficacy against all broad-leaved weed species present. No phytotoxic effect was observed on wheat.
