Ungasusa kanjani isibungu se-geranium

I-geranium yisitshalo okuthi, ngokunakekelwa okuyisisekelo okumbalwa, sikhule futhi siqhakaze okujabulisa ukusibona. Kodwa-ke, unesitha esingahle sibe khona, esimweni esibi kakhulu, esingamqeda. Igama layo lesayensi ngu UCacyreus marshalli, yize yaziwa kangcono ngamagama we-geranium worm noma i-geranium borer.

Lesi sinambuzane uvemvane olukala cishe u-2cm oluzalela amaqanda alo ezimbalini zezimbali ukuze izibungu zalo ziqedele umjikelezo wazo ngokudla ngeziqu zesitshalo. Kepha, Ingabe kukhona okungenziwa ukuyilawula?

Funda ukuhlukanisa

Uvemvane lwe-geranium luyisinambuzane esidabuka e-Afrika. Ifike eSpain ngo-1987, ingena esiqhingini saseMallorca, isebenzisa ukusika okwakugcwele amaqanda noma izibungu. Ukusuka lapho yasabalala ezweni lonke yadala umonakalo omkhulu kakhulu, ngoba yize endaweni yayo enezitha zemvelo, akukho noyedwa osatholakele lapha, ngakho inhlupho isakazeka kuphela.

Esigabeni sabantu abadala uvemvane olukala cishe u-2cm, okungumonakalo abawenzayo ukufaka amaqanda abo kuma-geraniums. Izibungu ngakolunye uhlangothi ziluhlaza ngokukhanyayo njengoba ubona esithombeni ngenhla, zinoboya, futhi yizo eziqala ukwenza buthakathaka izitshalo. Iziphungumangathi, nazo ezinoboya, ziluhlaza okomnyama, ziphenduka zibe nsundu usuku olulodwa noma ezimbili ngaphambi kokuba zikhule.

Idala muphi umonakalo?

Kuyisinambuzane esisebenza ngokushesha okukhulu, izikhathi eziningi lapho sibona izimpawu zokuqala lesi sitshalo sizodinga ukuthena okuhle ukuze silulame ngokuphelele. Izibungu ziyadla futhi zikhiphe iziqu, zizigwaze. Ngenxa yalokho, ukuncipha kwesitshalo kuyashesha, futhi amaqabunga azobuna ezinsukwini ezimbalwa.

Ingabe kukhona okungenziwa? Ngenhlanhla, yebo.

Ukulawulwa kovemvane lweGeranium

Nakhu ongakwenza ukugcina ama-geraniums enempilo unyaka wonke:

• Phatha kanye ngesonto ngeCypermethrin 10%, ukufafaza isitshalo (ekuseni ngovivi noma kusihlwa) nokunisela isisekelo. Kungasebenza njengokuvikela nokwelapha.
• Uma ukhetha ukusebenzisa amakhambi emvelo, ungenza imishanguzo yokuvikela ngama-pyrethrins emvelo kusetshenziswe nge-ejenti yokumanzisa (njenge insipho ye-potassiumngokwesibonelo) njalo ezinsukwini eziyi-3-4 phakathi nezinyanga ezifudumele.
• Ngaphambi kokuthenga, hlola zonke izingxenye zesitshalo kahle, ikakhulukazi iziqu. Uma ubona izimbobo kuzo, amaqabunga abunile, noma yini enye ongayithandi, ungayithengi ngoba kungenjalo ingathelela amanye ama-geraniums akho.
• Umanyolo unisele njalo ukukugcina uphilile.
• Esimweni lapho sekuvele kugcwele khona, usike iziqu ezithintekile.

Ngalezi zeluleko, i-geranium yakho nakanjani izokhula ngaphandle kwezinkinga 🙂.
