Abstract
A study on the efficacy of tank‐mix combinations on the growth of Leptochloa chinensis (L.) Nees and Scirpus grossus (L.) f. at the 3–4‐leaf stage was conducted under glasshouse conditions. Sethoxydim plus cyhalofop‐butyl at 8 + 25, 16 + 25, 32 + 25, 32 + 12.5, and 32 + 6.25 g ai ha −1 provided good control of L. chinensis , ranging from 89–95%. However, a comparison of the costs of herbicide mixtures revealed that sethoxydim at 32 g ai ha −1 plus cyhalofop‐butyl at 6.25 g ai ha −1 were the most cost‐effective among the combinations. For Scirpus grossus , bensulfuron plus 2,4‐D dimethylamine at 2.5 + 18, 5.0 + 18, 1.25 + 36, 2.5 + 36, and 5.0 + 36 g ai ha −1 gave good control that ranged from 88–93%. Tank‐mixing bensulfuron with 2,4‐D at 1.25 + 36 g ai ha −1 was, however, the most cost‐effective mixture compared to the other mixtures. None of the tank mixtures tested in this study caused injury to the rice seedlings. However, further field studies need to be undertaken to verify these findings.
