Use 30% glyphosate aqueous solution and 20% paraquat aqueous solution to control mango orchard weeds in Guangxi province,Baise city Tiandong county Guiqi mango base. The result shows that two agents each treatment control mango orchard weed with good effect. After 30 days of spraying,30% glyphosate aqueous solution's single and fresh weight control effect on gramineous weeds and broadleaf weeds both above 95%;after 3 days of spraying,20% paraquat aqueous solution control effect on gramineous weeds and broadleaf weeds over 90%,after 7 days of spraying every treatment's single and fresh weigh control effect above 95% besides treatment D is 93.91%. 30% glyphosate aqueous solution under 6 000 g/hm2 and 20%paraquat aqueous solution under 4 500 g/hm2 both safe to mango tree.
