Application of Gamma Irradiation and Its Convergent Treatments on Several Varieties of Oriental Hybrid Lily to Control Leaf Blight
In order to seek more eco-friend, economic and safer quarantine method than current methyl bromide fumigation, the convergent treatment with 200 Gy of gamma irradiation and several chemicals such as nano-siver particles (NSS), sodium dichloroisocyanurate (NaDCC) was tried on the cuttings of lily in...
