Izihlahla, kungakhathaliseki ukuthi zinakekelwa kahle futhi zinempilo kangakanani, zingathinteka ezinhlobonhlobo zezinambuzane ezincane. Amagciwane, amagciwane kanye nesikhunta esiyisinambuzane sihlala sihamba, silindele ukuthi ubonise uphawu oluthile lobuthakathaka, noma luncane kangakanani, ukuze luhlasele. Okunye okulimaza kakhulu yilokho esikwazi ngakho i-anthracnose noma i-canker, okungase kuthelele izitshalo ezincane, kubangele umonakalo ukuthi, uma ungelashwa ngesikhathi, ngeke ulungiseke.
Kodwa… ingabe kukhona ukwelashwa okusebenzayo ngempela ukukuqeda? Ngeshwa, uma sikhuluma ngama-microorganisms e-pathogenic, into kuphela esingayenza ukuvimbela nokwelapha izimpawu. Noma kunjalo ungakhathazeki ngoba lezo zinyathelo zokuvimbela ezenziwa ngesikhathi, ngokuvamile ziwumehluko phakathi kokuba nezihlahla, ake sithi ezivikelwe, nezihlahla ezifile.
Yini i-anthracnose?
Isithombe sithathwe ku-Flickr/Scot Nelson
I-anthracnose noma i-canker yisifo esibangelwa isikhunta esihlukahlukene, ikakhulukazi i-Colletotrichum ne-Gloeosporium genera. Kuvame kakhulu ezifundeni ezinesimo sezulu esifudumele kancane lapho umswakama wemvelo nawo uphezulu., njengoba lezi zimo zifanelekile ukuthi lezi zinambuzane ezincane zikhule ngokushesha ... ezinhlobonhlobo zezitshalo.
Ngokugxila ezihlahleni kuphela, i-canker ilimaza ngokukhethekile i-chestnut yamahhashi; empeleni, inegama layo: i-horse chestnut anthracnose. Kulesi sihlahla, sisesincane sihlasela amaqabunga, kodwa njengoba isitshalo sikhula, kuvame ukuvela amaqhubu noma 'izigaxa' esiqwini saso. Kodwa qaphela, uma unezihlahla zom-alimondi, umango noma izimbali ze-dogwoods, kufanele futhi uqaphe kakhulu, njengoba zingezinye izinhlobo eziyintandokazi zalezi sikhunta.
Yiziphi izimpawu?
Izimpawu zalesi sifo kulula ukuzibona:
- Ukubukeka kwamabala ansundu emaqabunga
- Ukuwa kweLeaf
- Izithelo ezinamabala ansundu/amnyama angagcina ewa
- Ukukhipha isisu
- Isihlahla sibukeka sengathi sibolile, asikhuli
- Izigaxa esiqwini (ezibonelweni zabantu abadala)
Isihlahla singenwa kanjani ukubola?

Isikhunta esibanga i-anthracnose noma i-canker singangena phakathi kwezihlahla uma ezinye zalezi zimo zenzeka:
Ukushisa + umswakama ophezulu
Ezifundeni lapho amazinga okushisa epholile noma efudumele, kuvame kakhulu ukuthola izitshalo ezithintekayo ngenxa ye-canker. Manje, kufanele ukhumbule ukuthi akudingekile ukuthi ube sendaweni enezinga lokushisa elingu-20ºC kanye nomswakama ongu-85% (isibonelo) unyaka wonke, njengoba Uma iziphethu zifudumele futhi zinomswakama lapho uhlala khona, ngisho noma ubusika bubanda neqhwa, ungase ube nezihlahla ezinegciwane.
Ukuthena ngamathuluzi angenawo amagciwane
Uma kuziwa ekutheneni, kubaluleke kakhulu, okokuqala ukukwenza ngesikhathi esifanele (ekwindla noma ngasekupheleni kwebusika, kuye ngokuthi uhlobo lwesihlahla), kodwa futhi nokuhlanza amathuluzi kahle. Ama-microorganisms awabonwa, kodwa lokho akusho ukuthi awekho. Ngakho ungangabazi ukuwabulala amagciwane ngaphambi nangemuva kokusetshenziswa ukuvimbela izifo.
Futhi ngendlela, ungakhohlwa ukuvala amanxeba nge-paste yokuphulukisa. Uma kwenzeka nje.
isihlahla sinakekelwe kahle
Uma isihlahla sithola konke esikudingayo, kuba nzima ukuthi sigule. Nakuba lokhu kungase kubonakale kuyinkimbinkimbi, ngoba ungakwazi ukuyinakekela kahle eyakho, uyichelele futhi uyifake umquba uma kunesidingo, kodwa isagula ... Kungani? Hhayi-ke, kungenzeka ukuthi isimo sezulu asisihle neze kuye, ukuthi wagula esevele esenkulisa.
Kunoma yikuphi, akulimazi ukuqhubeka nokwenza lokho nje: zama ukuba nazo zonke izidingo zomuthi zimbozwe.
Indlela yokwelapha i-anthracnose?
Isithombe sithathwe ku-Flickr/Scot Nelson
Njengoba sishilo ekuqaleni kwalesi sihloko, kunzima, noma akunakwenzeka, ukusiqeda ngokuphelele lesi sifo. Ngakho-ke, okwenziwayo yilokhu okulandelayo:
Izindlela zokuvimbela
- Thenga izihlahla ezinempilo
- Nisela amanzi futhi uvundise noma nini kunesidingo
- Phatha imbewu ngama-fungicides asekelwe ethusi ngaphambi kokuhlwanyela
- Sebenzisa ama-substrates 'amasha'
- Qiniseka ukuthi izimpande zinendawo eyanele yokukhula
- Hlukanisa izitshalo ezigulayo kwezinempilo
- Phatha nge-fungicide ekuqaleni kwenkathi yokukhula
izinyathelo 'zokwelapha'
Uma ubona ukuthi usunazo izimpawu, sebenzisa isikhunta esenziwe ngethusi. Futha amaqabunga nesiqu kahle, futhi ungakwazi ukwengeza umthamo okhonjiswe esitsheni emanzini okunisela namanzi, ngaleyo ndlela uphathe izimpande.
Ngithemba ukuthi lolu lwazi lube usizo kuwe ekwelapheni izihlahla zakho.

Ekwindla ka-2019 ngatshala umsedari waseLebanon obude obungama-75cm, ezinyangeni zokuqala wawohloza izinaliti zawo kakhulu kodwa entwasahlobo/ehlobo wakhula ngaphezu kwemitha eyi-1 futhi wawunhle kakhulu. Lokhu kuwa kuphinde kwaqothuka futhi kufana “nempandla” yakho konke. Ngithene igatsha futhi liluhlaza ngaphakathi nakuba lingenayo inaliti emehlweni.
Ngaso sonke isikhathi ngangiyivundisa ekuqaleni kwentwasahlobo nasekwindla, ngaphandle kokuyidlula ngokweqile, futhi yayitshalwe endaweni engaphansi kuka-5-5,5 exutshwe nenhlabathi yendawo kanye netshe elithile.
Ngihlala eGalicia, endaweni yaseCoruña, lapha ungabona eziningi ezikhula ngaphandle kobunzima.
Angazi ukuthi kumele kube yini lokhu ngoba ibola ekwindla (esi-2 esiyitshalile) ingabe isamile kahle?
Ngiyabonga ukubingelela ?

Kungenzeka ukuthi ayikaqedi ukumila kahle, ngenxa yokukhula kwayo kancane.
Kodwa uma kwenzeka, ngincoma ukuthi ngiyelapha nge-fungicide yama-conifers, njengoba kunesikhunta esifana ne-phytophthora ebangela lokho okwaziwa ngokuthi i-browning of conifers, ehlala ibulala kubo. Ngakho-ke, konke ukuvimbela kuncane.
Manje entwasahlobo, omunye umanyolo uzosebenza kahle, njengomquba, i-guano noma umquba othile (umquba wezinkukhu, inqobo nje uma womile, ulungile).
Ukubingelela!
