Example 6
The weeds (ohonagaaogeito (Palmer amaranth; Amaranthus palmeri), hosobainubiyu (common waterhemp; Amaranthus rudis), butakusa (common ragweed; Ambrosia artemisiaefolia), obutakusa (giant ragweed; Ambrosia trifida), himemukashiyomogi (marestail; Conyza canadensis), shiroza (common lambsquarters; Chenopodium album), hokigi (kochia; Kochia scoparia), inubie (common barnyardgrass; Echinochloa crus-galli), and akinoenokorogusa (giant foxtail; Setaria faberi)) and soybeans are seeded to a plastic pot. The plants are then grown in a greenhouse, and 21 days after seeding, 20 g/ha of the compound X and 935 mL/ha of ENGENIA® (dicamba BAPMA salt 600 g/L, manufactured by BASF Corp.) are applied to the foliage at the sprayed water amount of 200 L/ha. The plants are then grown in a greenhouse, and 14 days after the application, the effects on the weeds and crop injuries on soybeans are investigated. A synergistic weed control effect compared to the single use of each of the compounds is confirmed.
