The schematic diagram of experimental design. Non-GM treatment was always planted non-Bt rice (Minghui-86); GM was planted Bt rice (Kefeng-6); and Half-GM was a treatment where Bt rice was planted in one plot and non-Bt rice was planted in all adjacent plots. In consecutive year, Bt plot was changed to non-Bt plot, and vice versa. Reservation area was always planted non-Bt rice.
