I-Fludioxonil i-non-systemic contact fungicide yokukhusela izityalo

Ingcaciso yeMveliso

I-Fludioxonil sisibulala-ntsholongwane soqhagamshelwano.Isebenza ngokuchasene noluhlu olubanzi lwe-ascomycete, i-basidiomycete kunye ne-deuteromycete fungi.Njengonyango lwembewu ye-cereal, ilawula izifo ezibangelwa yimbewu kunye nomhlaba kwaye inika ulawulo olululo ngokukodwa lwe-Fusarium roseum kunye ne-Gerlachia nivalis kwiinkozo ezincinci.Njengonyango lwembewu yetapile, i-fludioxonil inika ulawulo olubanzi lwezifo eziquka iRhizoctonia solani xa isetyenziswa njengoko kucetyiswa.I-Fludioxonil ayichaphazeli ukuntshula kwembewu.Igalelwa njengesibulala-zinambuzane samagqabi, ibonelela ngamanqanaba aphezulu olawulo lweBotrytis kwizityalo ezahlukeneyo.Umchiza wokungunda ulawula izifo kwizikhondo, amagqabi, iintyatyambo kunye neziqhamo.I-Fludioxonil iyasebenza ngokuchasene ne-benzimidazole-, i-dicarboximide- kunye ne-guanidine-resistant fungi.

Indlela yayo yokwenza kukuthintela i-phosphorylation ye-glucose ehambelana nokuthutha, eyanciphisa izinga lokukhula kwe-mycelial.Njengomchiza wonyango lwembewu, i-ejenti yokwaleka kwembewu emisiweyo inokulawula izifo ezininzi.Iziphumo zesicelo zibonisa ukuba ukunkcenkceshela kweengcambu ze-fludioxonil okanye unyango lomhlaba luneziphumo ezihle kakhulu kwizifo ezininzi zeengcambu ezifana ne-wilt, ukubola kweengcambu, i-fusarium wilt kunye ne-vine blight yezityalo ezahlukeneyo.Ukongeza, i-fludioxonil ingasetyenziswa njengesitshizi ukuthintela ukungunda okungwevu kunye ne-sclerotia yezityalo ezahlukeneyo.

Ukujongana nezifo zokungunda, idla ngokusetyenziswa kunyango lwembewu kunye nonyango lwasemva kokuvuna iziqhamo.I-Fludioxonil iyasebenza kunyango lwezifo ezininzi eziphambili zembewu ezifana ne-seedling blight, i-stem-base Browning, i-snow mold kunye ne-common blunt.Kunyango lwasemva kokuvuna, inokujongana neGrey yokungunda, ukubola kokugcina, umgubo wokungunda kunye nebala elimnyama.Isebenzisa umphumo wayo ngokuphazamisa i-phosphorylation ehambelana nokuthutha ye-glucose kunye nokuvimbela i-glycerol synthesis, iphinde ivimbele ukukhula kwe-mycelial.Xa isetyenziswa kudityaniswe ne thiamethoxam kunye ne metalaxyl-M, i-fludioxonil ingasetyenziselwa ukunyanga izitshabalalisi ezifana nentwala yepesika-itapile, i-flea beetle kunye ne-cabbage stem flea beetle.
