Description

When molinate at 40 g/a was applied at the emerging stage of rice plant under water-submerged condition, it caused slight damage to rice, but when applied before seeding of rice it did not. The effect of molinate to barnyardgrass (Echinochloa Crus-galli P. Beauv, var. oryzicola Ohwi) was greater at the emerging and one-leaf stage of it than before the emerging, especially great at the emerging stage. The weeding effect of molinate was unstable under the percolating condition, and less in the clay loam than in the sandy loam. From these results, molinate is considered to be very useful for control of barnyardgrass in water-seeded rice at the dose of about 20 g/a at the emerging stage of the weed before seeding of rice.
