CAS 40596-69-8|Methoprene

Taw qhia
Methoprene ua raws li cov tshuaj tua kab mob tiv thaiv kab mob thiab cuam tshuam cov txheej txheem tshem tawm kab. Nws tuaj yeem cuam tshuam rau txoj kev loj hlob thiab kev loj hlob ntawm cov kab luam yeeb thiab luam yeeb hmoov borers, thiab ua rau cov neeg laus poob lawv lub peev xwm kev loj hlob, yog li tswj kom muaj kev loj hlob ntawm cov kab tsuag luam yeeb.
