Imithi yesundu zizityalo, nangona zibonakala ngathi ziyinyani zisengozini kakhulu kwizinto ezincinane ezibangela izifo. Ukugqithisa kwamanzi ngexeshana elifutshane, ukuthenwa okungakhange kwenziwe kakuhle, ukwehla ngesiquphe kwamaqondo obushushu, njl. iyakwazi 'ukuvusa' ukungunda, iintsholongwane kunye neentsholongwane ezingathandabuzi ukukwenzakalisa.
Nabani na obakhulisayo kuya kufuneka abanike ngononophelo abalufunayo ukuthintela izifo zomthi wesundu. Kodwa, ezizi?
Lethal tyheli

Sisifo esixhaphakileyo kwintsholongwane kwimozulu eshushu (akukho tyala lisafumanekayo eYurophu) elihlasela ikakhulu iintende zesikhokhonathi. Iimpawu zezi: tyheli kunye nokufa kwamagqabi, ukufa kweengcambu, ukubuna kwe-inflorescence, ukuwa kwangaphambi kwexesha kweziqhamo, ukujika kombala kwamagqabi kunye nokufa yomzekelo.
Akukho lunyango lusebenzayo, kodwa unyango lwe-tetracycline ngeedosi ze-1 ukuya kwi-3 yegrama yesundu rhoqo kwiinyanga ezine ziyanceda ukusithintela kwaye sisithintele isifo ekuqhubekeni.
I-anthracnose
I-anthracnose kwi-chestnut.

Sisifo sokungunda esiveliswa ngundo IGraphiola phoenicis Yintoni ebangela ukubonakala amancinci, amachaphaza angaqhelekanga okanye iipustules ezimthubi okanye ezimdaka ngebala 1cm okanye ngaphantsi. Ihlasela iintlobo ezahlukeneyo zemithi yesundu: iPhoenix, iRoystonea, iHowea, iChademedorea ...
Kuyaliwa ne-Oxycarboxin.
I-Fusariosis
Sisifo sokungunda esidluliselwa ngundo lweFusarium ichaphazela amagqabi asisiseko, ezifumana umbala omthubi kwaye zome. Ngelishwa, umthi wesundu onesifo uhlala ufa kungekudala.
Akukho lunyango, kodwa lukhona uthintelo: ukuthenga izityalo ezisempilweni, ukusebenzisa izixhobo ezicocekileyo, imihlaba esezantsi kunye nomhlaba, kunye nokulawula unkcenkceshelo kunciphisa amathuba osulelo.
Ukuhamba kwamagqabi

Ilwa ne-fungicides esekwe kuManeb okanye eBenomil.
Ukubola okupinki
Umfanekiso - Forestryimages.org
Sisifo sokungunda esiveliswa ngundo IGliocadium vermoeseni yintoni unobangela Amabala Necrotic okanye chlorotic emagqabini, kunye necrotic amabala kunye exudation kwi iziqu. Ezona ntlobo zibuthathaka zezo ze-genus Chamaedorea neDypsis; Ngapha koko, inokubangela umonakalo omkhulu kwiPhoenixes nokuba idityaniswa neFusarium.
Akukho lunyango. Into ebaluleke kakhulu ukuba uyenze kukwenza uthintelo ngeTriforin okanye isalfure.
Siyathemba ukuba iluncedo kuwe kwaye uyayazi into enokwenzeka kumthi wesundu wakho.
Ndineentende ze-areca apho i-stipite yahlulwe ngobude obuphakathi, ndingenza ntoni?

Ewe, le nto uyithethayo inomdla kakhulu. Ndiyazi ngetyala lomthi wesundu otyalwe ngokutsha, isitampu saphulukana namanzi amaninzi, kodwa sabuya sabuya umva, umboko wadumba emva koko waqhekeka.
Ke umbuzo wam ngulo: ngaba ubutshintshile kutshanje? Ngokomgaqo ayifanelanga ukuba yingxaki enkulu. Ukuba ufuna ukubeka unamathiselo wokuphilisa kubo, kodwa boy, kufuneka bahlale bephila kwaye bekhula.
