Uma kuziwa ekuhlobiseni ikhaya lethu, enye yezimbali ezidume kakhulu yi-geraniums. Nakuba kunezinhlobo ezingaphezu kuka-250 ezihlukene zalolu hlobo, zimbalwa kakhulu kuzo ezisetshenziselwa ukuhlobisa indawo yethu. Kodwa-ke, zonke izinhlobo zalezi zitshalo zingahlushwa izifo nezinambuzane ezihlukahlukene. Ukuze sivikele imifino yethu futhi siyisindise uma ihlaselwe, kubalulekile ukuthi sazi ukuthi sibona kanjani ukuthi yini eyilimazayo ukuze sisebenzise ukwelashwa ngokushesha ngangokunokwenzeka. Ukwenza umsebenzi wakho ube lula, Sizochaza ukuthi yiziphi izifo ezivame kakhulu ze-geranium nokuthi zingaphathwa kanjani.
Inhloso ukuthola ulwazi oluyisisekelo oluhlobene nama-pathologies angathinta lezi zimbali ukuze ukuze ukwazi ukuhlonza i-pathogen eyimbangela nokwelapha isitshalo ngokushesha ngangokunokwenzeka. Ngokuvamile, imifino esiyithenga kunoma yisiphi isikhungo sengadi, ezinkulisa noma ezindaweni ezinkulu ngokuvamile inempilo. Izifo zivame ukuvela kamuva, kodwa ngani? Hhayi-ke, kungase kube ngenxa yokungaphathwa kahle nokunakekelwa kwesilimo noma ngenxa yokuhlasela kwangaphandle kwezingadi eziseduze, amasimu noma amasimu ezithelo.
Yiziphi izifo ezithinta i-geranium?
Njengoba sesike sasho ngaphambili, i-geranium ingaphathwa yizifo ezihlukahlukene, ezinye zazo zingalimaza kakhulu lezi zimbali, yingakho kubaluleke kakhulu ukuzibona kusenesikhathi futhi zelaphe. Kufanele kuqashelwe ukuthi ukubonakala kwezinambuzane ngokuvamile kuholela ekubukeni kwezifo eziningi. Nakuba kuyiqiniso ukuthi sizogxila kulokhu kokugcina, sizophinde sibhale uhlu lwezinambuzane ezivame ukuhlasela ama-geraniums kaningi, ukucabangela 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. Kuyisifo sokukhunta esibangelwa ukhunta I-Puccinia sp.. Isibonakaliso esibaluleke kakhulu salesi sifo ukubonakala kohlobo lwama-pustules amnyama ngaphansi kwamaqabunga. Lawa ma-pustules athambekele ekubeni abe nombala osawolintshi ngokuhamba kwesikhathi. Lapho amaqabunga ehlaselwa kakhulu yilesi sikhunta, agcina omile.
Njengoba ukugqwala kuyisifo esithathelwanayo futhi okunzima ukulwa nakho, kungcono kakhulu shisa zonke izitshalo ezithintekile ukwenza isiqiniseko sokuthi sibhubhisa ama-spores abo.
I-Botrytis
Phakathi kwezifo ezaziwa kakhulu ze-geranium yi-botrytis, ebangelwa yi- I-Botrytis cinerea. Ngokuvamile livela ezindaweni ezinomswakama futhi ezipholile. Lokhu akuthinti amaqabunga kuphela, kodwa futhi nezimbali zezimbali. Ngokuvamile, lezo zindawo ezithintekayo yilesi sifo ziyabola futhi zimbozwe uhlobo lwesikhunta esimpunga esimnyama.
Singayivimbela kanjani i-botritis? Indlela engcono kakhulu yokubeka ama-geraniums endaweni enomoya omuhle futhi uvimbele isitshalo ekulimaleni, ngoba i-pathogen ingangena lapho. Kungashiwo lokho kukhona ama-fungicides athile ukulwa ne I-Botrytis cinerea.
Isikhunta se-Powdery
Esinye sezifo ezidume kakhulu ze-geranium yi-powdery mildew, kulokhu okubangelwa ukhunta okuthiwa Erysiphe spp.. I-pathology kulula kakhulu ukuyibona, ngoba uphawu lwayo oluyinhloko ivela ohlangothini olungaphezulu lwamaqabunga ngendlela emhlophe noma i-ashen powder. Izindawo ezithintwa yile pathogen ngokuvamile ziba phuzi zize zome.
Lapho ukwelapha isitshalo esihlaselwe yi-powdery isikhutha, kungcono kakhulu sebenzisa isibulala-sikhunta esithile ("ama-antioides") futhi ususe ezinsukwini ezimbalwa kamuva wonke lawo magatsha namaqabunga angenwe ukhunta. Indlela enhle yokuzama ukuvimbela ukubonakala kwalesi sifo kuma-geraniums wethu ukuwabeka endaweni enomoya omuhle.
I-Alternariosis
Kukhona futhi i-alternariosis, esinye isifo se-geranium esivamile. Imbangela yalokhu ukhunta okuthiwa I-Alternaria spp.. Ukuze sithole lesi sifo, kufanele sibheke amaqabunga amadala atholakala maphakathi noma engxenyeni engezansi yesitshalo. Kuzoba namachashaza amancane ansundu. Ukuze welaphe isitshalo esithintekile, kufanele sisebenzise ama-fungicides asekelwe ethusi.
I-Anthracnose
I-Anthracnose ingesinye isifo sokukhunta esithinta ama-geranium kaningi. Lokhu kubangelwa ukhunta I-Gloeosporium pelargonii. Lapho isitshalo singenwa yigciwane, Amachashazi amancane amnyama noma ansundu avela emaqabunga, imiqumbe, kanye nezimbali. Ngokuhamba kwesikhathi, la mabala agcina enwebeka kuze kube yilapho yonke indawo ethintekile ibuna. Kukhona enye isikhunta, okuthiwa I-Ascochyta spp.., okubangela amabala afana kakhulu.
Isixazululo sale pathology siwukuthi sebenzisa ama-fungicides athile ngokushesha nje lapho sibona izimpawu zokuqala zesifo. Kubaluleke kakhulu ukuthi, lapho selapha isitshalo, simanzise yonke ingxenye yasemoyeni.
isifo sonyawo
Ekugcineni kufanele sigqamise inkinga yonyawo, imbangela yayo isikhunta I-Pythium spp. Lesi sifo sokukhunta ngokuvamile sihlasela intamo yesitshalo. Leyo ndawo igcina ibolile, okuholela ekufeni kwegeranium. Ivamise ukuvela ezitshalweni ezisencane nezike zaniselwa ngamanzi amaningi, okubangela ukugcwala kwamanzi enhlabathini. Lapho lesi sitshalo sithinteka, intamo yesiqu iba mnyama endaweni ephansi. Ngezinye izikhathi kuhambisana nohlobo lwempushana ekhanyayo necacile.
Ukwelapha lesi sifo, kungcono ukuncibilikisa isibulala-sikhunta esithile emanzini bese unisela isitshalo ngale ngxube. Ngaphezu kwalokho, kubaluleke kakhulu ukugcina inhlabathi imanzi ngaphandle kokuyikhukhula. Lokhu kwelashwa kungasetshenziswa futhi ukuvimbela ukubonakala kwalesi sikhunta.
Ngithemba ukuthi uthole lesi sihloko esikhuluma ngezifo ze-geranium siwusizo futhi sinolwazi. Khumbula lokho ukuthola i-phytopathology ngesikhathi kungabalulekile ezitshalweni, futhi hhayi kuphela kulabo abathintekayo, kodwa nalabo ababazungezile. Isikhunta sisakazeka kalula futhi kungaba nzima kakhulu ukuziqeda, ngakho kufanele sizame ukuvimbela ukubukeka kwazo.
