Influence of tank mixtures of pre-emergence herbicides on growing leeks (Allium porrum L.)

Abstract

The effect of mixtures of pre-emergence herbicides on weed infestation and yield of leek was evaluated. Three tank mixtures were applied: s-metolachlor (Dual Gold 960 EC at a dose of 80 ml/da) + oxyfluorfen (Goal 2 E at a dose of 100 ml/da); smetolachlor (Dual Gold 960 EC at a dose of 60 ml/da) + oxyfluorfen (Goal 2 E at a dose of 75 ml/da); and s-metolachlor (Dual Gold 960 EC at a dose of 40 ml/da) + oxyfluorfen (Goal 2 E at a dose of 50 ml/da). The number of weeds was recorded following the application of the tank mixture. It was found that treatment with a tank mixture of herbicides Dual Gold 960 EC and Goal 2 E caused a reduction in weed infestation at all three application rates as compared to the control. The lowest weed infestation was established after treatment with the highest doses of herbicides. It was suggested that the applied herbicide mixture could be used effectively at the leeks growth stage.
