Isithombe: Ama-Pustules Amhlophe Okugqwala Ngaphansi Kweqabunga Le-Mustard
Kushicilelwe: Mashi 16, 2026 22:30:49 UTC
Isithombe esikhulu esinokulungiswa okuphezulu esibonisa ama-pustules amhlophe aqoqene eduze kwemithambo ngaphansi kweqabunga lesinaphi, eqokomisa izimpawu zesifo sesitshalo ezinemininingwane.

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.
Usayizi ojwayelekile (1,536 x 1,024)
Usayizi omkhulu (3,072 x 2,048)

Incazelo yesithombe
Lesi sithombe se-landscape macro esinesinqumo esiphezulu sithwebula ingxenye engezansi yeqabunga lesinaphi ngemininingwane ecacile, sembula ukuqubuka okukhulu kwesifo sokugqwala okumhlophe. Ubuso beqabunga eliluhlaza bugcwalisa uhlaka ngokuvundlile, ngemithambo eluhlaza ekhanyayo evelele eqhamuka ngaphandle njengenethiwekhi yezimbambo eziphakanyisiwe. Ezihlanganiswe ndawonye kule mithambo futhi zisakazeke phakathi kwazo kukhona ama-pustule amaningi amhlophe acwebezelayo anobukhulu obuhlukahlukene. Ama-pustule ngalinye libonakala liphakanyisiwe futhi liyindilinga kancane, linobuso obunobuthuntu, obufana ne-cauliflower obubonisa ukuthi kunezinhlayiya ze-spore eziqinile ngaphansi kwesendlalelo esithambile se-epidermal. Amanye ama-pustule mancane futhi afana nama-bead, kanti amanye ande aba ama-dome amakhulu, angajwayelekile aphuma ngokuhlukile ebusweni beqabunga.
Izicubu zeqabunga ezizungezile zibonisa ukushintsha kombala okuncane, kanye nokukhanya okuphuzi okuncane kanye nama-chlorotic halos azungeze ama-pustules amaningi. Umbala oluhlaza okwesibhakabhaka weqabunga uhluke kakhulu nombala okhanyayo, ocishe ube yi-ivory wezitshalo ze-fungus, okwenza ukutheleleka kubonakale kumangalisa. Izinwele ezinhle zamaqabunga kanye nokuthungwa okuncane kobuso kuyabonakala, okwengeza ekubalweni ngokoqobo nasekucaceni kwesayensi kwesithombe. Imithambo ibonakala ijiyile kancane futhi inombala okhanyayo, iqondisa iso kulo lonke ukwakheka futhi igcizelela indlela ama-pustules avame ukuhlangana ngayo ezindleleni zemithambo yegazi.
Ukukhanya kuthambile futhi kuyalingana, kugqamisa isakhiwo se-pustules esinezinhlangothi ezintathu ngaphandle kwezithunzi ezinzima. Ukujula kwensimu okungajulile kugcina amaqoqo aphakathi egxile kakhulu ngenkathi kufiphaza kancane imiphetho engaphandle yeqabunga, kudala umuzwa wokujula nobukhulu. Isithombe siveza ubuhle bezitshalo kanye nesifo sezitshalo, sibonisa izimpawu eziphawulekayo zokugqwala okumhlophe ezitshalweni ze-brassica. Umbono we-macro oningiliziwe uvumela ababukeli ukuthi baqonde ukuthungwa kwe-granular kwama-pustules agcwele i-spore kanye nokwakheka okubucayi kweqabunga elingaphansi.
Sekukonke, isithombe sisebenza njengokubonakaliswa okucacile nokufundisayo ngokwesayensi kokutheleleka kokugqwala okumhlophe emaqabungeni e-mustard, sihlanganisa ukwakheka kobuhle nemininingwane yokuxilonga efanele imfundo yezolimo, ukuhlonza izifo zezitshalo, noma izinto zokubhekisela zezitshalo.
