Abstract

Limnocaris flava (L.) Buchenau (yellow bur head) is an aggressive broadleaf weed in lowland rice ecosystem. Resistance of L. flava to herbicides like synthetic auxins and acetolactate-synthase inhibitor has been reported in Malaysia. The study was, therefore, conducted to reconfirm the resistance of L. flava to bensulfuron-methyl and 2,4-D, and subsequently to determine the efficacy of herbicide mixtures in controlling the resistant biotype of L. flava. For screening out the resistant biotype, different rates up to 16 times higher than recommended doses of bensulfuron methyl and 2,4-D were applied. To control resistant biotype, different rates of bensulfuron methyl and bentazon-sodium/MCPA dimethyl in single or in combinations were tried against five week-old resistant biotype of L. flava. Results showed that resistant L. flava biotype tolerated up to 4 times higher than recommended doses of bensulfuron methyl and 2,4-D. Bentazon-sodium/MCPA dimethyl alone effectively controlled resistant biotype of L. flava at the recommended rate (0.74 kg a.i/ha), while bensulfuron-methyl alone failed to control resistant biotype of L. flava even at double the recommended rate. Among the different tank-mix combinations of bensulfuron methyl and bentazon-sodium/MCPA dimethyl, three antagonistic and six additive joint actions were observed.
