Rice production is highly affected byweed competition. The efficacy of chemicalweed control and crop safety is
a function of absorption, translocation and metabolism of herbicides. This study investigates the effect of cold stress 22/16 ∘C
(day/night) on absorption, translocation andmetabolism of 14C-bispyribac-sodium on rice seedlings.
RESULTS: Maximum 14C-bispyribac-sodium absorption occurred at 24 h after herbicide treatment and was stimulated by the
warm 30/22 ∘C (day/night) temperature. A large amount of total absorbed herbicide was retained in the treated leaf, indicating
that bispyribac-sodium had minimal translocation to other plant parts. Piperonyl-butoxide (a P450 inhibitor) plus herbicide
caused greater injury than the herbicide alone. In addition, injury on rice plantswas enhanced by exposure to cold, emphasizing
the negative effect on herbicidemetabolism. In the thin-layer chromatography metabolism experiment, cold-grown plants had
higher injury and retained more of the parent herbicide than plants grown at a warm temperature.
CONCLUSION: Cold stress reduces bispyribac-sodium absorption and metabolism in rice, but has no effect on translocation. |
