| Abstract: | The different amount of Ally,Chlorsulfuron and Express was sprayed on the sown pastureareas of puccinellia chinampoensis and Phragmites australis. Those herbicides can prevent andwipe out Cirsium setasum. effectively, which is the poisonous weeds. The preventing effects ofplants and fresh weight in Cirsium setasum are direct proportion with spraying herbicides. Among these herbicides, the effect of Ally (25 % ) 22. 5g/hm2 or Chlorsulfuron (25 % )4. 5g/hm2 arebest. |
