Uptake and translocation of o-sec-butylphenyl N-methylcarbamate (BPMC) and O,O-diisopropyl S-benzyl phosphorothiolate (IBP) in rice plants applied as single and mixed preparations.


PMID 7362899

Abstract

When BPMC was applied as single or mixed preparation with IBP to rice plants, BPMC absorbed through roots and translocated to upper portions. The uptake and dissipation of BPMC in rice plants were not different between both preparations. The disappearance of BPMC in plant was rapid and residue level of BPMC was below 0.2 ppm 15 days after treatment. On the other hand, the concentration of IBP applied as mixed preparation decreased slowly as compared with that of BPMC. The persistence of IBP in rice plants was considerably long, and it may be due to the high stability in plants.
