Calcium cyanamide was also found efficient in controlling plant parasitic nematodes population which resulted in reduction nematode reproduction rate.
Three soil conditioners 900 kg/hm2 of quicklime (96% CaO, supplied by Makepolo, China), 375 kg/hm2 of calcium cyanamide (containing 19.8% N, 50% CaO, provided by Ning Xia Yuan Da Xing Bo Chemical Co, NingXia, China.) and 210 kg/hm2 of microbial agents (Heshenyuan multi- effect bacteria with an effective Bacillus content exceeding 2 billion/g, provided by Parti China (Beijing) Biotechnology Co., Ltd.) were applied to the replanted tobacco field.
