Evaluation on Control Effect of Different Herbicides with Different Concentrations to Annual Grass Weeds of Rice Fields in Fujian Area
摘要
Abstract
In order to effectively control annual grass weeds of rice fields in Fujian , three herbicides with different concentrations ,including 1% oxaziclomefone suspending agent , 10% bispyribac‐sodium suspension and 20%Cyhalofop‐butyl oil suspension ,were selected to control grass weeds ,such as Echinochloacrusgalli (L .) Beauv ., Leptochloachinensis (Linn .) Nees in Youyang township of Xianyou ,Putian city .The results showed that :20%Cyhalofop‐butyl oil suspension is the best herbicide in direct seeding paddy fields to control grass weeds and the control effect was above 80% after 30 d‐treatment . The recommended concentrations of the herbicide ranged from 45 g · hm -2 to 105 g · hm-2 (active ingredient ) with the water 675 L · hm-2 . Under the recommended concentrations , the herbicide is safe to rice .关键词
