In order to effectively eliminate Stellera chamaejasme L., two kinds of complexing agents were applied to study the chemical control of Stellera chamaejasme for three years. The results showed that in the current year, the top part of the eradication of Euphorbia pulcherrima died, the growth point of necrosis, the elimination rate of 90.0%. The root of dead edema decay and necrosis, greening rate of 0 .0% ~ 2.3%, to eliminate the entire plant. Good pasture content and yield increased by 6.0% and 1.4% -9.1% respectively.
