Comparative Study on the Inhibitory Effects of Sprout Inhibitors on Tobacco

[Objective] The research aimed to lay good foundation for further enhancing the yield and quality of flue-cured tobacco. [Method] With tobacco cultivar CB-1 as test materials,with 11 kinds of chemical sprout inhibitors such as Liannong( Pendimethalin) as test agents,their sprout inhibition rate,sprout inhibitory effects and pesticide injury were compared by field experiment. [Result] The comprehensive inhibitory effects of Yafeng( 25% Flumetralin dispersable suspending agent) was the best and that of salt was the worst. Different sprout inhibitors didn't cause the pesticide injury. The comprehensive inhibitory effects of Yiyamin( flumetralin),Chuyatong( 33% pendimethalin EC),Yawei( 37. 3% butralin EC),Dunpaiyansu( Clomazone-brutralin),Cacaotong( 33% pendimethalin) were better and their sprout inhibition rates were all more than 83% and the sprout inhibitory effects was higher than 89%. [Conclusion] The research could provide test basis for screening safe,efficient and low-cost tobacco
