Abstract：The grading standard for carrot black rot was established according to its occurance characteristics and symptom during carrot growing period．Further studies on the field controlling effect of 7 different fungicides to carrot black rot and the yield increasing role were carried out．The results showed that all these different fungicides had certain controlling effects to carrot black rot，and along with the improvement of controlling effect，the effect of yield increasing was remarkably increased．The best one among them was 40% chlorothalonil SC with 76.38% of controlling effect and the yield increasing rate was 84.21%．
