The invention provides a field adult-plant-stage rice brown planthopper resistance identification method, and belongs to the technical field of agriculture, and the method comprises the following steps: S1, after double-parent transplantation of insect-susceptible variety TN1 seedlings with drugs, inoculating brood female adult brown planthoppers for insect source batch feeding; s2, after seed soaking, germination accelerating and sowing are conducted on the identification material and the control variety, transplanting with medicine, single planting, small-interval cross arrangement and normal field water and fertilizer management are conducted; s3, in a tillering period, covering the material plot with a nylon net cover, artificially inoculating a brown planthopper insect source, performing normal field water and fertilizer management, and not applying pesticide in the test plot in the whole growing season; s4, when the plant fatality rate of the insect-susceptible control plot reaches 90%, the plant death
