I-Fludioxonil ingavimbela futhi ibulale amagciwane.Indlela ye-bactericidal iwukuphazamisa futhi ibhubhise inqubo ye-biological oxidation kanye ne-biosynthesis

amabhaktheriya, abhubhise iketango le-hydrophobic kulwelwesi lwamangqamuzana amagciwane, futhi akhiphe futhi ancibilikise izinto eziyinhloko zemisebenzi yokuphila yamagciwane.

Ukudluliswa kweglucose okuhlobene ne-phosphorylation ukuvimba ukukhula kwe-mycelium fungal.

I-Fludioxonil ingasetshenziswa njengokwemboza imbewu, isifutho, nokuchelela ngezimpande, futhi iyasebenza ekulweni nokubola, ukubola kwezimpande, isikhunta esimpunga, kanye nesikhunta okwenzeka ezitshalweni ezihlukahlukene.

Isifo senuzi kanye ne-Fusarium wilt zinemiphumela yokulawula.

Uyini umsebenzi nokusetshenziswa kwe-fludioxonil?

1. Umsebenzi

(1) I-Fludioxonil inemiphumela yokubulala amagciwane kanye ne-antibacterial.Ku-Botrytis cinerea, indlela yayo yokubulala amagciwane ukuphazamisa nokucekela phansi i-oxidation yayo yebhayoloji.

kanye nenqubo ye-biosynthesis (okungukuthi, ncibilikisa udonga lwamaseli e-Botrytis cinerea) futhi ibhubhise ngokushesha ulwelwesi lwamaseli we-Botrytis cinerea Ikhipha oxidize futhi

incibilikisa izinto eziyinhloko zemisebenzi yokuphila yamagciwane, futhi ibhubhise ukwakheka kwe-nucleic acid namaprotheni.

(2) I-Fludioxonil ivimbela ukukhula kwe-fungal mycelium ngokuvimbela ukudluliswa okuhlobene ne-glucose phosphorylation, futhi ekugcineni iholele ekufeni kwe-pathogen.

Ukufa.

2. Injongo

(1) I-Fludioxonil ayinakho ukumelana nezibulala-sikhunta ezikhona, futhi ingasetshenziswa njengezibulala-sikhunta zokwelapha imbewu kanye nama-ejenti alengayo ahlanganisa imbewu.Lapho ukwelapha i

imbewu, isithako esisebenzayo sizomuncwa kuphela ngenani elincane, kodwa singabulala amagciwane ebusweni bembewu kanye nejazi lembewu.

(2) Uma usebenzisa i-fludioxonil ukunisela izimpande noma ukwelapha inhlabathi, ingavimbela futhi ilawule ukubola kwezimpande, i-fusarium wilt, blight, blight nezinye izifo.

ezitshalweni ezihlukahlukene.Lapho ufutha, kungavimbela i-sclerotinia, isikhunta esimpunga nezinye izifo.

Ungayisebenzisa kanjani i-fludioxonil

1. Ukugqoka

Lapho utshala ummbila, amazambane, ukolweni, ubhontshisi wesoya, ugalikhi, ukhukhamba, amakinati, amakhabe, amakhabe nezinye izitshalo, kusebenzise ngaphambi kokuhlwanyela.

I-agent engu-2.5% ye-fludioxonil yokumisa imbewu yokugqoka imbewu, isilinganiso soketshezi nembewu ngu-1:200-300.

2. Ukucwilisa izimbali

(1) Lapho utshala upelepele, ama-eggplant, amakhabe, utamatisi, izucchini, ama-strawberry, ukhukhamba, amakhabe nezinye izitshalo, sebenzisa u-2.5% we-fludioxonil suspension

gxilisa ingqondo izikhathi ezingu-200 (isidakamizwa esingu-10ml esixutshwe namanzi angu-2kg) + 0.1% we-chlorfenuron amanzi Gcoba izimbali izikhathi ezingu-100-200 ze-ejenti.

(2)Ngemva kokucwilisa izimbali, ingavimbela isikhunta esimpunga, igcine amacembe emisha isikhathi eside, futhi ivimbele imifino enjengama-eggplant notamatisi ekuboleni.

3. Futha

Ingasetshenziswa esigabeni sokuqala sesifo ukuvimbela isikhunta esimpunga samagilebhisi, ama-strawberries, upelepele, ama-eggplant, ukhukhamba, utamatisi, amakhabe nezinye izitshalo.

2000-3000 izikhathi uketshezi 30% pyridoyl·I-fludioxonil suspension concentrate kufanele ifuthwe kanye njalo ezinsukwini ezingama-7-10.

4. Ukuchelela izimpande

Ukuvimbela ukubola kwe-fusarium kanye nokubola kwezimpande ku-eggplant, ikhabe, ikhukhamba, utamatisi, ama-strawberry nezinye izitshalo, izimpande zinganiselwa izikhathi ezingu-800-1500 ze-2.5%

Ukumiswa kwe-fludioxonil kugxila esigabeni sokuqala sesifo, kanye njalo ezinsukwini eziyi-10, nokunisela ngokuqhubekayo izikhathi ezingama-2-3.
