Abstract

Red sorrel (Rumex acetosella L.) is a troublesome perennial weed in the alpine grasslands of Kangwon Province of Korea. A number of soil- and foliar-applied herbicides were evaluated for their efficacy of red sorrel control. In greenhouse experiments, no soil-applied herbicides, such as pendimethalin, simazine, alachlor, metolachlor, ethalfluralin controlled red sorrel, however, foliar-applied herbicides, such as glufosinate, paraquat, glyphosate, glyphosate + 2,4-D, dicamba, mecoprop, 2,4-D, bentazone controlled more than 60% of red sorrel 2 weeks after treatments. When dicamba and 2,4-D were applied to red sorrel in different growth stages, the auxin-type of herbicides cold control red sorrel regardless of growth stage. This result implies that the auxin-type herbicides can be applied between early May (early growth stage) and mid lune (before fruit maturation) at Kangwon alpine grasslands. In a field experiment, glufosinate at 1.0 kg a.i, $ha^{-1}$, glyphosate at 3.28 kg a.i. $ha^{-1}$, dicamba at 0.96 kg a.i. $ha^{-1}$, and mecoprop at 150 kg a.i. $ha^{-1}$ controlled more than 80% of red sorrel 4 weeks for treatment, suggesting such herbicides could be applied for red sorrel control at Kangwon alpine grasslands.
