Abstract: To investigate the phytotoxicity of drifted herbicides applied in corn fields on flue-cured tobacco in corn-tobacco intercropping areas, seven common corn herbicides38% atrazine SC, 7% 2, 4-D butyl ester EC, 20% fluroxypyr EC, 56% MCPA-Na (2-methyl-4-chlorophenoxy acetic acid-sodium) WP, 15% clodinafop-propargyl WP, 10% tribenuron-methyl WP and 15% mesotrione SCwith lower harm for flue-cured tobacco were selected and their phytotoxicity was tested on five flue-cured tobacco varieties. Seven treatments were set as following:recommended dose(RD), 10^-1 RD, 2×10^-1 RD, 5×10^-1 RD, 10^-2 RD, 1.5×10^-2 RD and water (as the control). The damage grades of tobacco seedlings after treatment were recorded and the phytotoxicity index and incidence were analyzed. The results showed that within the appropriate dosage ranges, seven corn herbicides significantly affected the growth of flue-cured tobacco. Drug damages of 2, 4-D butyl ester and fluroxypyr were the most serious. Under 1.5×10^-2 RD treatments, most tobacco plants displayed clear damage symptoms. The phytotoxicity of seven corn herbicides were in the order of 2, 4-D butyl ester and fluroxypyr > MCPA-Na > tribenuron-methyl and mesotrione > atrazine and clodinafop-propargyl. Yunyan87 and Zhongyan100 had lower tolerance to six corn herbicides. NC55 and K326 had higher tolerance to most corn herbicides. Therefore, it is recommended that in corn fields near tobacco-planting areas, atrazine and clodinafop-propargyl are preferred, followed by mesotrione and tribenuron-methyl. MCPA-Na should be used with caution, while 2, 4-D butyl ester and fluroxypyr should be avoided.
