Control Efficacy of Different Post-Emergence Herbicides Against Acalypha australis
摘要
Abstract
In order to screen the suitable herbicides for control Acalypha australis,the efficacy of 11 post-emergence herbicides were compared by pot experiment.The results showed that,at the doses set in this experiment,25％fomesafen AS,20％fluroxypyr EC and 38％atrazine SC achieved 100％control efficacy against A.australis at 2-leaves-3-leaves,their fresh weight control efficacy against A.australis at the 6-leaves exceeded 93％.The 25％bromoxynil octanoate EC also reached 100％control efficacy against A.australis at 2-leaves-3-leaves,but exhibited poor control efficacy against the 6-leaves weeds.In addition,10％mesotrione OD,30％topramezone SC,8％tembotrione OD and 84％cloransulam-methyl WG exerted a good inhibitory effect on A.australis at 2-leaves-3-leaves,with the fresh weight control efficacy higher than 90％,while their control efficacy against the 6-leaves weeds were unsatisfactory.40 g·L-1 nicosulfuron OD,480 g·L-1 dicamba AS and 480g·L-1 bentazone AS could not effectively control A.australis.关键词
