Abstract
|
|
|
|
Red sorrel, as one of exotic weeds in Korea, was introduced along with imported cereals for concentrate feed or within the seed for forage production. The plant was dominated in grassland and reduced the quality of forage. In particular, this weed cause severe problem in alpine grassland. This study was carried out to investigate the effect and response of red sorrel and forage crops by foliar and soil applied herbicide application. Mecoprop(MCPP) and pendimethaline were selected by pre-field experiment trials and applied to control the red sorrel in grassland. herbicidal activity of MCPP was 77.2％ at 500㎖／10a level and 82.8％ at 750㎖／10a level. However, seedling growth of germinated red sorrel. The herbicidal activity of pendimethalin to the red sorrel seedling was 83.0％ 2 times application of MCPP at the rate of 750㎖／10a was effective to control of red sorrel regrown from root and herbicidal activity was 93.2％ MCPP and pendimethaline treatment was not reduced growth of grass and have no herbicidal injury to forage crop seedling. Amount of MCPP and pendimethalin remained in grass plant was decreased from 20 days after after herbicide treatment and could not be problem in livestock feeding.
