Kushicilelwe: Mashi 16, 2026 22:30:49 UTC
Isithombe esiningiliziwe sendawo yesitshalo sesinaphi esibonisa izimpawu ezicacile ze-downy mildew, okuhlanganisa izilonda ze-chlorotic eziphuzi kanye nokukhula kwesikhunta okumpunga-okumhlophe emaqabunga.

Izinguqulo ezitholakalayo zalesi sithombe
Amafayela ezithombe atholakalayo ukuze alandwe ngezansi awacindezelwe kakhulu futhi anesisombululo esiphezulu - futhi ngenxa yalokho, ikhwalithi ephezulu - kunezithombe ezifakwe ezihlokweni nasemakhasini akule webhusayithi, ezilungiselelwe kangcono usayizi wefayela ukuze kuncishiswe ukusetshenziswa komkhawulokudonsa.

Incazelo yesithombe
Lesi sithombe sendawo esinekhwalithi ephezulu sibonisa umbono oningiliziwe wesitshalo sesinaphi esithinteke kakhulu yi-downy mildew. Lesi sitshalo sihlala maphakathi nohlaka, namaqabunga aluhlaza abanzi anwebeka ngaphandle ngokuvundlile, edala ukwakheka okunezingqimba nokuthungwa ngokumelene nesizinda esifiphele kancane samaqabunga aluhlaza aminyene. Ukujula okungajulile kwensimu kuhlukanisa isitshalo esithelelekile, kudonsela ukunaka emaphethini ayinkimbinkimbi ezimpawu zesifo ezibonakalayo emaqabunga aso.
Isici esiphawuleka kakhulu ukuba khona okukhulu kwe-downy mildew emaqabunga. Izilonda ze-chlorotic eziphuzi ngokuphaphathekile, ezingamile ngendlela engavamile zisakazeke ezindaweni eziphezulu zamaqabunga, zakha amabala anamabala ahluke kakhulu nohlaza olujulile lwezicubu ezinempilo. Ezindaweni eziningana, izilonda ziyahlangana zibe amabala amakhulu, okubonisa ukutheleleka okuthuthukile. Emithanjeni yamaqabunga naphesheya kwe-lamina, ukukhula kwesikhunta okuthambile kodwa okubonakalayo okumpunga-okumhlophe, okuphansi kubonakala. Lokhu kuhlanganiswa okufiphele, okunemicu kubonakala kuminyene kakhulu ezingxenyeni ezingezansi zamaqabunga angaphambili, okuwenza abonakale enothuli noma enolwembu. Ukuthungwa kwesikhunta kuhluke ekukhanyeni kwemvelo kanye nokushwabana okuncane kwamaqabunga e-mustard, kugcizelela isimo sesitshalo esibucayi.
Naphezu kokutheleleka, lesi sitshalo siyaqhakaza. Esikhungweni esiphezulu salesi sitshalo, kuvela iqoqo lezimbali ezincane eziphuzi ezikhanyayo zama-mustard ezivela emahlumela aluhlaza ahlanganiswe kahle. Izimbali, ngayinye enamacembe amane ahlukile ahlelwe ngendlela efana ne-cross-like, zinikeza umbala ocacile ogqamile omelene namahlamvu anesifo. Izimbali zibonakala zintsha futhi ziqondile, zifanekisela ukukhula okuqhubekayo ngisho noma amaqabunga ekhombisa izimpawu ezicacile zokucindezeleka. Iziqu ziqinile futhi ziluhlaza, zikhula phezulu ukuze zisekele iqoqo lezimbali kanye namahlumela engeziwe angakavulwa.
Imininingwane emincane ithuthukisa ukuba ngokoqobo kwendawo. Imithambo emincane idlula eqabungeni ngalinye, futhi amaconsi amancane omswakama anamathela ebusweni bamaqabunga, ebamba ukukhanya futhi enezela umuzwa womswakama wendawo—izimo ezivame ukuba ngcono ekukhuleni kwe-downy mildew. Amaphethelo amaqabunga agobile kancane futhi angalingani, kanti ezinye izindawo zibonakala zinciphile noma zisontekile ngenxa yokutheleleka. Ingemuva liqukethe uphahla oluluhlaza olufanayo, olungabonakali kahle, oluqinisa indawo yezolimo noma yengadi ngaphandle kokuphazamisa isihloko esiyinhloko.
Sekukonke, isithombe sihlanganisa imininingwane yezitshalo kanye nokugula kwezitshalo, okubonisa ngokucacile izimpawu ezibonakalayo ze-downy mildew kuma-mustard. Umehluko phakathi kwezimbali eziphuzi ezikhanyayo namaqabunga anamabala, ambozwe yi-mildew udala indaba ebonakalayo ekhangayo yokuqina phakathi kwezifo, okwenza isithombe sibe nolwazi lwesayensi futhi sihehe ngokubonakalayo.
