Uma kukhulunywa ngokuhlobisa amakhaya ethu, ama-geranium aphakathi kwezimbali ezithandwa kakhulu. Nakuba kunezinhlobo ezingaphezu kuka-250 ezahlukene zalolu hlobo, zimbalwa kakhulu kuzo ezisetshenziselwa ukuhlobisa indawo esizungezile. Kodwa-ke, zonke izinhlobo zalezi zitshalo zingahlushwa izifo nezinambuzane ezahlukahlukene. Ukuze sivikele izitshalo zethu futhi sizisindise uma kwenzeka zihlaselwa yizifo, kubalulekile ukuthi sazi ukuthi singazibona kanjani izinto ezizilimazayo ukuze sikwazi ukusebenzisa ukwelashwa ngokushesha okukhulu. Ukuze senze izinto zibe lula, sizochaza izifo ezivame kakhulu zama-geranium nokuthi singazelapha kanjani.
Umgomo ukuthola ulwazi oluyisisekelo mayelana nezifo ezingathinta lezi zimbali ukuze kutholakale igciwane elibangela lesi sifo futhi kwelashwe isitshalo ngokushesha okukhulu. Ngokuvamile, izitshalo esizithengayo ezikhungweni zengadi, ezindaweni zokugcina izitshalo, noma ezitolo ezinkulu ziphilile. Izifo zivame ukuvela kamuva, kodwa kungani? Kungaba ngenxa yemikhuba emibi yokulima noma ukutheleleka okuvela ezingadini eziseduze, emasimini, noma ezivandeni zezithelo.
Yiziphi izifo ezithinta i-geranium?
Njengoba sishilo ngaphambili, ama-geranium angahlushwa izifo ezahlukahlukene. Ezinye zazo zingaba yingozi kakhulu kulezi zimbali, yingakho kubalulekile ukuzibona nokuzelapha kusenesikhathi. Kubalulekile ukuqaphela ukuthi ukuhlasela kwezinambuzane kuvame ukuholela ekukhuleni kwezifo eziningi. Ngenkathi sizogxila kulezi zifo, sizobala nezinambuzane ezivame ukuhlasela ama-geranium, ukuze uqonde ukuthi yini engabangela umonakalo omkhulu kangaka:
- IGeranium Butterfly
- Isicabucabu esibomvu
- Izintwala
- Impukane emhlophe
- Ama-Mealybugs
- Amacimbi
- i-green midge
- Ama-Nematode
Manje njengoba sesiyazi ukuthi yiziphi izinambuzane ezivame kakhulu, sizokhuluma ngezifo ezivame kakhulu ze-geranium nokuthi zingaphathwa kanjani.
Roya
Sizoqala ngokugqwala. Lesi yisifo se-fungus esibangelwa yi-fungus i- Puccinia sp . Uphawu oluvelele kakhulu lwalesi sifo ukuvela kwama-pustules amnyama ngaphansi kwamaqabunga. La ma-pustules avame ukuphenduka abe nombala ophuzi ngokuhamba kwesikhathi. Uma amaqabunga ehlaselwe kakhulu yi-fungus, ekugcineni ayoma.
Njengoba ukugqwala kuyisifo esithathelwanayo kakhulu futhi okunzima ukusilawula, indlela engcono kakhulu yokwenza iwukushisa zonke izitshalo ezithintekile ukuqinisekisa ukubhujiswa kwezinhlamvu zazo. Ukuze uthole ulwazi olwengeziwe mayelana nokuvimbela ezitshalweni, ungabheka izindlela zokulima izimbali.
I-Botrytis
Phakathi kwezifo ze-geranium ezaziwayo kakhulu yi-botrytis, ebangelwa yi- Botrytis cinerea . Ivame ukuvela ezindaweni ezipholile nezimanzi. Lesi sifo asithinti amaqabunga kuphela kodwa namahlumela ezimbali. Ngokuvamile, izindawo ezithintekile ziyabola futhi zimbozwe yisikhunta esimpunga esimnyama.
Singakuvimbela kanjani i-botrytis? Indlela engcono kakhulu ukubeka ama-geranium endaweni enomoya omuhle futhi ugweme ukulimaza isitshalo, njengoba yile ndlela igciwane elingangena ngayo. Kubalulekile ukuqaphela ukuthi kunemithi ethile yokulwa ne-Botrytis cinerea . Uma udinga ulwazi olwengeziwe mayelana nokwelashwa, ungavakashela isigaba sethu sasekhaya semithi yezitshalo.
Isikhunta se-Powdery
Esinye isifo esivamile se-geranium yi-powdery mildew, ebangelwa yi-fungus i-Erysiphe spp . Kulula kakhulu ukuyibona, njengoba uphawu lwayo oluyinhloko luvela phezulu kwamaqabunga njengempuphu emhlophe noma e-ashy. Izindawo ezithintekile zivame ukuba phuzi bese ekugcineni zomile.
Uma welapha isitshalo esithintekile yi-powdery mildew, indlela engcono kakhulu yokwenza lokhu ukusebenzisa i-fungicide ethile (umkhiqizo "olwa ne-mildew") , bese kuthi ngemva kwezinsuku ezimbalwa, ususe wonke amagatsha namaqabunga atheleleke yi-fungus. Indlela enhle yokuzama ukuvimbela lesi sifo kuma-geranium akho ukuwabeka endaweni enomoya omuhle. Ungathola futhi ulwazi olwengeziwe mayelana nezitshalo zonyaka ezingaba isengezo esihle ekhaya lakho.
I-Alternariosis
I-Alternaria leaf spot ingenye yesifo esivame kakhulu se-geranium. Sibangelwa yi-fungus i-Alternaria spp . Ukuze uthole lesi sifo, bheka amaqabunga amadala engxenyeni ephakathi noma engezansi yesitshalo. Kuzovela amabala amancane ansundu lapho. Ukuze welaphe isitshalo esithintekile, sebenzisa ama-fungicides asekelwe kuthusi.
I-Anthracnose
I-Anthracnose ingenye isifo sesikhunta esivame ukuthinta ama-geranium. Sibangelwa isikhunta i- Gloeosporium pelargonii . Uma isitshalo sithelelekile, kuvela amabala amancane amnyama noma ansundu emaqabunga, amahlumela, kanye namahlumela ezimbali. Ngokuhamba kwesikhathi, lawa mabala asakazeka kuze kube yilapho yonke indawo ethintekile ibuna. Esinye isikhunta, esibizwa nge- Ascochyta spp ., sibangela amabala afanayo kakhulu.
Isixazululo sale nkinga ukusebenzisa imithi yokubulala isikhunta ethize ngokushesha nje lapho ubona izimpawu zokuqala zesifo. Kubaluleke kakhulu ukuthi, lapho welapha isitshalo, umanzise zonke izingxenye ezingenhla komhlaba, futhi uma unesifiso sokufunda kabanzi ngendlela yokunakekela izitshalo zakho, ungabheka lesi sihloko sendlela yokunakekela izitshalo zakho.
isifo sonyawo
Okokugcina, kumele sikhulume ngokubola kwezinyawo, okubangelwa yi-fungus Pythium spp. Lesi sifo se-fungus sivame ukuhlasela isisekelo sesitshalo. Le ndawo ekugcineni iyabola, okuholela ekufeni kwe-geranium. Ngokuvamile ibonakala ezitshalweni ezincane eziniselwe kakhulu, okubangela ukugcwala kwamanzi. Lapho isitshalo sithintekile, isisekelo sesiqu siba mnyama ezingeni lomhlabathi. Ngezinye izikhathi lokhu kuhambisana nento elula, efana nempuphu.
Ukwelapha lesi sifo, indlela engcono kakhulu ukuncibilikisa isikhunta esithile emanzini bese unisela isitshalo ngale ngxube. Kubaluleke kakhulu futhi ukugcina inhlabathi imanzi kodwa ingagcwali amanzi. Lokhu kwelashwa kungasetshenziswa futhi ukuvimbela isikhunta ukuthi singaveli kwasekuqaleni.
Ngiyethemba ukuthi uthole lesi sihloko ngezifo ze-geranium siwusizo futhi sinolwazi. Khumbula ukuthi ukuthola izifo zezitshalo kusenesikhathi kungabaluleka ezitshalweni, hhayi kuphela kulabo abathintekile kodwa nakulabo abazungezile. Isikhunta sisakazeka kalula futhi kungaba nzima kakhulu ukusiqeda, ngakho-ke kumelwe sizame ukuvimbela ukubonakala kwaso.
