In the lake orchard of A Lake experimental demonstration center, different concentrations of carbofuran EC, insecticide and monocrotophos were used to control the pesticide efficacy of pear orchard scale. The field efficacy comparison test showed that the effect of killing pesticide and pest was better than that of pea it is good. Among them, the control efficacy of 1000 times of pesticide on the 6th day was 100.00%, 1 200 times and 98.73% respectively, and the insecticidal efficiency of 300 times was 96.64%, significantly higher than that of the monocrotophos 800 times 35.23% .
