In greenhouse trials in 1998-1999, the effects of using new spray techniques on the activity of two herbicides for broad-leaved weeds control were examined. Also retention of spray solution containing herbicides with and without addition of oil adjuvant on Chenopodium album and Sinapsis alba leaves was measured. Results showed that air induction and convcntional flat fan nozzle gave similar control of tested plants, except Chenopodium album control where fine sprays applied with conventional flat fan nozzle improved efficacy comparcd with very course spray obtained with air induction nozzle. Also results showed that oil adjuvant addition cnhanced biological efficacy for all nozzles, regardless of using herbicide and controlled plant species. Droplet size was the most important factor determining spray retention and activity of herbicides. Efficacy of spray retention depends on the wetting characteristics of the plant, spray application and solution factors.
