Fludioxonil non-systemic contact fungicide kuteteza mbewu
Mafotokozedwe Akatundu
Fludioxonil ndi mankhwala opha tizilombo.Ndiwothandiza motsutsana ndi mitundu yambiri ya ascomycete, basidiomycete ndi deuteromycete bowa.Monga mankhwala a mbewu ya phala, imateteza matenda obwera ku mbewu ndi nthaka ndipo imathandizira makamaka Fusarium roseum ndi Gerlachia nivalis mutirigu wa timbewu tating'ono.Monga chithandizo cha mbewu ya mbatata, fludioxonil imapereka kuwongolera kosiyanasiyana kwa matenda kuphatikiza Rhizoctonia solani ikagwiritsidwa ntchito movomerezeka.Fludioxonil sichikhudza kumera kwa mbewu.Amagwiritsidwa ntchito ngati mankhwala ophera bowa, amapereka mphamvu zambiri za Botrytis ku mbewu zosiyanasiyana.Mankhwalawa amalimbana ndi matenda pazitsa, masamba, maluwa ndi zipatso.Fludioxonil imagwira ntchito motsutsana ndi benzimidazole-, dicarboximide- ndi bowa wosamva guanidine.
Njira yake ndikuletsa phosphorylation yokhudzana ndi kayendedwe ka glucose, yomwe imachepetsa kukula kwa mycelial.Monga fungicide yochizira mbewu, woyimitsa mbewu woyimitsidwa amatha kuthana ndi matenda ambiri.Zotsatira zakugwiritsa ntchito zikuwonetsa kuti kuthirira kwa mizu ya fludioxonil kapena kuthirira nthaka kumakhala ndi zotsatira zabwino pa matenda ambiri amizu monga wilt, rot rot, fusarium wilt ndi vine choipitsa cha mbewu zosiyanasiyana.Kuphatikiza apo, fludioxonil itha kugwiritsidwanso ntchito ngati kutsitsi kuteteza imvi nkhungu ndi sclerotia ya mbewu zosiyanasiyana.
Pothana ndi matenda oyamba ndi fungus, amagwiritsidwa ntchito pochiza mbewu komanso pochiza zipatso pambuyo pokolola.Fludioxonil ndi othandiza pochiza matenda ambiri ambewu monga mbande choipitsa, tsinde-base Browning, nkhungu ya chipale chofewa komanso kusawoneka bwino.Pochiza pambuyo pokolola, imatha kuthana ndi Gray nkhungu, zowola zosungira, powdery mildew ndi mawanga akuda.Zimagwira ntchito yake posokoneza phosphorylation yokhudzana ndi kayendedwe ka glucose komanso kulepheretsa kaphatikizidwe ka glycerol, ndikulepheretsa kukula kwa mycelial.Ikagwiritsidwa ntchito limodzi ndi thiamethoxam ndi metalaxyl-M, fludioxonil itha kugwiritsidwanso ntchito pochiza tizirombo monga pichesi-mbatata aphid, utitiri kachilomboka ndi kabichi tsinde utitiri kachilomboka.
CropUses:
mbewu za mabulosi, chimanga, kugwiririra mafuta, mbatata, phala, manyuchi, soya, zipatso zamwala, mpendadzuwa, turf, masamba, mipesa
