Abstract
This study was conducted to develop an eco-friendly control method for water foxtail in the field sowing barley seeds before rice harvesting. When sea water was applied pre-emergent, 1 and 2 leaves, little injury was observed on barley. Percent of water foxtail control with sea water (100%) was more than 50% at 1 leaf application timing. When sodium chloride was applied 400, 800 and $1,600kg\;ha^{-1}$, little injury was observed on barley. Percent of water foxtail control with sodium chloride was 36-44% at 30 days after sowing. When ferrous sulfate was applied at 400, 800 and $1,600kg\;ha^{-1}$, emergent injury was observed 35-50% on barley. Percent of water foxtail control with ferrous sulfate was 48-79% at 30 days after sowing. When barley was sowed at 200, 300 and $400kg\;ha^{-1}$, seeding rate standing plants have many of the more crops, water foxtail occurrence was low. And, Forage yield of 300 kg ha-1 seeding in the highest. Based on the results, it is possible to control water foxtail in the field sowing barley seeds before rice harvesting more than 50%.
