    Abstract

    A series of adjuvants were developed to improve herbicide performance when applied through air induction nozzles. A series of research trials were conducted in 2004 and 2005 with clethodim, foramsulfuron, and glyphosate. Efficacy of these herbicides was reduced in over 30 % of all cases when applied through air induction nozzles compared to conventional flatfan nozzles. However, when modified forms of the adjuvants were used, efficacy increased approximately 25 % of cases with glyphosale, 40 % of cases with clethodim, and 90 % of cases with foramsulfuron when using air induction nozzles. A separate series of oil-based adjuvants developed had over 20 % air entrapment whereas conventional oil-based adjuvants had 5 % or less air entrapment when using air induction nozzles. Research conducted in the field in 2005 indicated that these novel formulations may improve herbicide efficacy.
