2,3-difluoro-5-chloropyridine yog ib qho tseem ceeb nruab nrab rau kev sib txuas ntawm cov tshuaj tua kab muaj txiaj ntsig zoo acetochlor. Nyob rau hauv kaum xyoo tsis ntev los no, fluorinated tshuaj tua kab tau tsim sai heev, thiab tau dhau los ua qhov tseem ceeb ntawm txoj kev loj hlob ntawm kev lag luam tshuaj tua kab hauv ntiaj teb. Ntawm lawv, fluorinated pyrethroids thiab fluorinated benzoylurea tshuaj tua kab yog tsim thiab siv ntau dua.
