Control of herbicide resistant Limnocharis flava (L.) Buchenau using herbicides mixtures
Limnocaris flava (L.) Buchenau (Yellow bur head) is an important broadleaf weed in rice fields (Azmi 2003). This weed spreads throughout South East Asia especially in the rice crop (Azmi 2003). It has been reported resistance to 2,4-D and metsulfuron methyl in Indonesia and Malaysia respectivel...

| description | Limnocaris flava (L.) Buchenau (Yellow bur head) is an
important broadleaf weed in rice fields (Azmi 2003). This
weed spreads throughout South East Asia especially in the
rice crop (Azmi 2003). It has been reported resistance to
2,4-D and metsulfuron methyl in Indonesia and Malaysia
respectively (Heap 2005). Herbicide mixture may help to
prevent resistance problem as well as shifts in weed
population which is always associated with the use of a
single herbicide (Wrubel and Gressel 1994). Little study
has been conducted to determine the effect of herbicide
combination to control biotype resistant of L. flava in
Malaysia. The purpose of this study was to determine the
effect of bensulfuron-methyl, bentazon sodium/MCPA
dimethyl, singly or in combination on resistant biotype of
L. flava. A field experiment has been conducted in 2006 at
weed experimental Plot, MARDI Stesyen, Seberang Prai,
Penang, Malaysia to control herbicide resistance biotype
of Limnicharis flava (L.) Buchenau using bensulfuronmethyl
and bentazon sodium/MCPA dimethyl. The 5
weeks old plants were treated with single herbicide or a
combination of the two herbicides. The herbicide rates
used were half of recommended rate, recommended rate
and double recommended rate. The results shows that
bentazon-sodium/MCPA dimethyl at the recommended
(0.74 kg a.i/ha) or higher rates alone controlled biotype R
of L. flava effectively. Bensulfuron-methyl alone at all
rates did not control L. flava. Of all tank-mix combination
treatments of bentazon sodium/MCPA dimenthyl and
bensulfuron-methyl, three antagonistic and six additive
joint actions were observed. |
