Impact of Different Adjuvants and Modes of Application on Efficacy of Rimsulfuron in Maize

Abstract

Field studies were conducted in order to investigate the efficacy of herbicide rimsulfuron in maize with three various commercial products (WG and OD formulations), in combination with three different nonionic adjuvants (Extravon, Trend 90 and Break- Thru S240). The investigation was carried out at two different locations during two years. The application of products in combination with adjuvants was done in one and two steps. The efficacy was evaluated on five weed species. The results demonstrated that the addition of any of the adjuvants improved the efficacy of rimsulfuron, but that there were no significant differences between products of different producers in the case of same or different formulation of rimsulfuron. Two different modes of application had no impact on efficacy.

U poljskim uslovima ispitivana je efikasnost različitih komercijalnih proizvoda rimsulfurona (WG i OD formulacije) u kombinaciji sa tri različita nejonska okvašivača (Extravon, Trend 90 and Break-Thru S240) u suzbijanju korova u kukuruzu. Ispitivanja su obavljena na dva lokaliteta u toku dve godine. Primena herbicida u kombinaciji sa okvašivačima obavljena je jednokratno i dvokratno. Efikasnost rimsulfurona je praćena na pet odabranih korovskih vrsta. Rezultati istraživanja su pokazali da svaki od ispitavnih okvašivača povećava efikasnost rimsulfurona, ali da nije bilo značajne razlike između različitih komercijalnih preparata, kao ni različitih formulacija rimsulfurona. Takođe, dva različita načina primene nisu uticala na efikasnost ovog herbicida.
