Abstract:: The ex periment of evaluating entazon -quizalofop -P -ethy l joint -action w as conducted ing reenhouse .The method of Sing le Axial Isoble w as used in the experiment .The result show ed bentazon -quizalofop -P mix ture had sy nergism to Digitaria sanguinalis .As the dosage of bentazon increased f rom 0 to 600g a .i ./ha , the ED90 value of quizalofop -P to D .sanguinalis decreased from 14 .88 g a .i ./ha to 4 .89g a .i ./ha .When the combinations of bentazon -quizalofop -P were in low dosages , they had antagonism to Amaranthusret roflexus ;In higher dosages , they had synergism .
