【Abstract】 The field tests of Hemiberlesia pitysophila control with 40% methidathion EC,40% chlorpyriphos EC,40% omethoate EC,95% petroleum oil and 45% malathion EC were conducted. The results showed that spraying with 40% methidathion EC((1∶1 000))+40% chlorpyriphos EC(1∶1 000)+40% omethoate EC(1∶500)to be the most effective by orthogonal design in the field. Moreover,compared with using 40% methidathion EC,40% chlorpyriphos EC and 40% omethoate EC alone,the compound was more effective and reached an control effect of over 90%.更多还原
