Weed control in corn is a major challenge due to increasing problems with highly dominant
weed species and herbicide resistance evolution. Common lambsquarters and johnsongrass
constitute up to 80% to 90% of the weed population in many spring crops, such as soybean
[Glycine max (L.) Merr.], sunflower (Helianthus annuus L.), and corn, in Serbia. Currently,
acetolactate synthase–inhibiting herbicides, such as the systemic selective sulfonylurea nicosul-
furon, are most commonly used for chemical weed control of those species. A better under-
standing of the impact of nozzle type and adjuvant use on nicosulfuron efficacy can help to
improve control of common lambsquarters and johnsongrass and minimize herbicide resis-
tance development. Field trials were conducted in Serbia from 2020 to 2022 to evaluate the
impact of two adjuvants (a non-ionic surfactant [NIS] and a mineral fertilizer ammonium sul-
fate [AMS]) and two nozzle types (drift-reducing nozzles and flat-fan nozzles) on... common
lambsquarters and johnsongrass control using nicosulfuron. Satisfactory biomass reduction
of common lambsquarters (83% to 87%) and johnsongrass (83% to 97%) was achieved after
nicosulfuron application. Adding a NIS adjuvant increased the biomass reduction for common
lambsquarters (94% to 98%) and johnsongrass (90% to 100%) independently of the nozzle type
used. Selection of nozzle type did not show consistent effects on common lambsquarters and
johnsongrass control. Nicosulfuron efficacy was increased with NIS adjuvant for both nozzle
types compared to nicosulfuron solo for both species, and Extended Range (XR) TeeJet® nozzles
on average resulted in a higher efficacy for common lambsquarters compared to Turbo TeeJet ®
induction. Adding a mineral AMS adjuvant resulted in lower biomass reduction for both nozzle
types and weed species (65% to 78% and 61% to 91% for common lambsquarters and johnson-
grass, respectively). Corn grain yield was predominantly influenced by annual meteorological
conditions and adjuvant type added to nicosulfuron. This research suggests that addition of the
non-ionic adjuvant is an essential factor for successful control of common lambsquarters and
johnsongrass in corn and enables use of drift-reducing nozzles.
