PROBLEM TO BE SOLVED: To provide a rice production method capable of producing high-grade rice by controlling spotted rice stink bugs from paddy fields without using chemically synthesized pesticides to prevent spotted rice damage. SOLUTION: Grapes weeds are sown and weeded at least twice in a predetermined period before and after the heading time of rice, and at the time of rice harvest, a first region with a lot of spotted brown rice and a second region with a little spotted rice The brown rice harvested from the first area and the brown rice harvested from the second area are stored separately, and the brown rice obtained from the first area is color-sorted by a color sorter and color-sorted by a color-sorting process. The produced clean brown rice and the brown rice obtained from the second region are mixed, and the mixed brown rice is shipped as production rice. Because weeding is done at least twice, weeds can be kept in a state where heads of grasses do not head for a predetermined period before and after the heading time of rice, thereby reducing the damage of spotted rice stink bugs and suppressing their damage it can.
