Fipronil mankhwala opha tizilombo toyambitsa matenda komanso tizirombo

Mafotokozedwe Akatundu

Fipronil ndi mankhwala ophera tizirombo otakata omwe amagwira ntchito polumikizana komanso kuyamwa, omwe amagwira ntchito motsutsana ndi akulu ndi mphutsi.Zimasokoneza dongosolo lamanjenje lapakati pa tizilombo posokoneza gamma-aminobutyric acid (GABA) - njira yoyendetsera chlorine.Ndi systemic muzomera ndipo ingagwiritsidwe ntchito m'njira zosiyanasiyana.Fipronil angagwiritsidwe ntchito panthawi yobzala kuti athetse tizirombo m'nthaka.Itha kugwiritsidwa ntchito mumzere kapena ngati gulu lopapatiza.Zimafunika kulowetsedwa bwino m'nthaka.Mapangidwe a granular a mankhwalawa atha kugwiritsidwa ntchito powulutsa ku mpunga wa paddy.Monga mankhwala a foliar, fipronil imakhala ndi zoletsa komanso zochiritsa.Mankhwalawa ndi oyeneranso kugwiritsidwa ntchito ngati mankhwala ambewu.Fipronil ili ndi trifluoromethylsulfinyl moiety yomwe ili yapadera pakati pa agrochemicals ndipo motero iyenera kukhala yofunika kwambiri pakuchita bwino kwake.

M'mayesero am'munda, fipronil sanawonetse phytotoxicity pamitengo yovomerezeka.Imayang'anira mitundu ya organophosphate-, carbamate- ndi pyrethroid-resistant ndipo ndi yoyenera kugwiritsidwa ntchito pamakina a IPM.Fipronil samalumikizana molakwika ndi ALS-inhibiting herbicides.

Fipronil amawonongeka pang'onopang'ono pa zomera komanso pang'onopang'ono m'nthaka ndi m'madzi, ndi theka la moyo wake kuyambira maola 36 ndi miyezi 7.3 kutengera gawo lapansi ndi mikhalidwe.Imakhala yosasunthika m'nthaka ndipo ili ndi kuthekera kochepa kolowera m'madzi apansi.

Fipronil ndi poizoni kwambiri ku nsomba ndi zamoyo zam'madzi.Pachifukwa ichi, kutaya zotsalira za fipronil (mwachitsanzo m'mitsuko yopanda kanthu) m'mitsinje kuyenera kupewedwa.Pali chiwopsezo cha chilengedwe cha kuipitsidwa kwa madzi kuyambira pakutha kwa madzi pambuyo pothira kupita ku ng'ombe zazikulu.Komabe chiwopsezochi ndi chochepa kwambiri kuposa chomwe chimalumikizidwa ndi kugwiritsa ntchito fipronil ngati mankhwala ophera tizilombo.
