Abstract
Five chemical agents of 40% culling rate EC,20% triazine methidathion EC,5% cypermethrin white emulsion,48% chlorpyrifos EC and homemade lime sulfur have been used for pest control tests of Pseudaulacdapis pentagona in Walnut grafting farm of Jingdong County. Results showed that 1000 times 40% culling rate EC and 1000 times 20% triazine methidathion EC have best effects on pest control,but the effects of 2000 times 5% cypermethrin white emulsion and 2000 times 48% chlorpyrifos EC on pests control are general; homemade lime sulfur has poor efficacy of pest' s control.
