Zusammenfassung:To investigate the effect of soil-dressing in carrot field on pests occurrence, totally 50 fields cultivating carrot were chosen within Pyeongchang area, where highland adoptable carrots were cultivated every year. Also, occurrence degree of pests was surveyed by species and by times for 5 carrot fields including one pesticide-free field. In addition, relationship between phytophagous nematode density and soil physico-chemical components (soil pH, EC, content of NH₄-N, NO₃-N, organic matter, P, Ca, Mg, and K) was analyzed.
