I. Kev siv Pymetrozine
Siv rau kev tswj cov aphids nyob rau hauv nplooj zaub (Cop Group 4), qos yaj ywm, highbush blueberries, haus luam yeeb, Rhodiola rosea, sab nraum zoov ornamentals, tsev cog khoom zaub (kua txob, lws suav, dib thiab eggplant), thiab tswj Balsam twig aphid ntawm Christmas ntoo.

Zoo heev tiv thaiv kab tsuag xws li aphids (paj rwb, nplej, txiv duaj aphids), planthoppers (xim av, dawb-rov qab, grey planthoppers), whiteflies (tsev cog khoom thiab qos yaj ywm whiteflies), thiab leafhoppers (me me ntsuab leafhoppers).
Cov hauv qab no yog cov chaw siv ntawm cov khoom:
Muaj peev xwm thaiv cov kab mob kab mob los ntawm kev ua kom kab tsuag tsis pub noj, txo cov kab mob ntawm cov nroj tsuag xws li Qos Ntoo Yob Virus (PLRV) thiab Qos Ntoo Virus Y (PVY).
Tsim nyog siv rau hauv kev tswj kab tsuag sib xyaw (IPM) vim nws qhov kev xaiv zoo thiab tsis tshua muaj tshuaj lom rau cov kab muaj txiaj ntsig xws li xya-spotted ladybug (natural yeeb ncuab ntawm paj rwb bollworms), kab laug sab ntsuab, thiab kab laug sab (natural yeeb ncuab ntawm leafhoppers thiab planthoppers) .
II. EPA Classification thiab Mechanistic Arguments
EPA tau faib cov pymetrozine raws li "zoo li" tib neeg cov kab mob carcinogen raws li cov qog tshwm sim hauv ob hom (rat thiab nas), hauv ob hom poj niam (nas), thiab hauv ob hom (siab benign hepatoma thiab / lossis carcinoma). Mechanistic sib cav tau dhau los piav qhia txog kev mob carcinogenicity.
Cov hauv qab no yog cov chaw siv ntawm cov khoom:
III. Ceev faj
Nws yuav tsum raug sau tseg tias thaum siv pymetrozine, nws yog ib qho tsim nyog yuav tsum tau ua raws li kev siv kom raug thiab siv ntau npaum li cas kom ntseeg tau tias nws ua tau zoo thiab kev nyab xeeb.
