Amakhambi ayi-11 e-Colorado potato beetle lapho utshala amazambane ukuvikela izilimo eziyizigaxa
Ukulwa ne-Colorado potato beetle sekuvele kuyindaba evamile kulabo abafuna ukutshala amazambane esizeni sabo. Ukuze uthole umphumela, izicupho ezihlukahlukene zibekwe eduze kwemibhede yamazambane, izihlahla zithululwa ngothuli futhi zifafazwe ngamalungiselelo ahlukahlukene, ngisho nezinambuzane ziqoqwa ngesandla. Ngaphezu kwakho konke lokhu, kunenye indlela efakazelwe futhi ephumelelayo yokuvikela isivuno "ku-colorados", futhi lokhu ukwelashwa kwezilimo eziyizigaxa.
Okuqukethwe
Kungani kuyadingeka ukwelashwa ngaphambi kokutshala kwezilimo eziyizigaxa?
Ukucubungula izilimo eziyizigaxa ngaphambi kokutshala kuyindlela ephumelelayo esiza ukuvimbela ukulimala kwamazambane yi-Colorado potato beetle nezinye izinambuzane eziyingozi. Le ndlela idumile phakathi kwabalimi abanolwazi, njengoba inezinzuzo eziningi.
Into ephathwa ngayo izilimo eziyizigaxa ingena eziqwini nasemaqabungeni engxenye engenhla yesitshalo ngesikhathi sokukhula. Ngenxa yalokhu, izihlahla zamazambane zimelana nezinambuzane eziningi futhi azidingi kufafazwa ngama-insecticide isikhathi eside.
Izihlahla zamazambane ezikhule ngezilimo eziyizigaxa ezilashiwe azidingi ukuphathwa ngezibulala-zinambuzane. Lokhu kunciphisa ingozi yokungenwa ushevu kubaphathi, izilwane ezifuywayo kanye nezinambuzane ezinenzuzo.
Ukwelashwa ngaphambi kokutshala kusiza ukuvikela izilimo eziyizigaxa ezifweni zefungal kanye ne-bacterial, kanye nezinambuzane ezingaphansi komhlaba.
Wenziwa kanjani ukwelashwa preplant of nezilimo eziyizigaxa
Kunezindlela ezimbili eziyinhloko zokuvikela izilimo eziyizigaxa ngaphambi kokutshala: ukufafaza nokucwiliswa ngesisombululo esikhethekile.
ukufutha
Ukufafaza izilimo eziyizigaxa ngaphambi kokutshala, kubaluleke kakhulu ukwenza ngaphandle esimweni sezulu esizolile. Inqubo yokucubungula okunjalo imi kanje:
- Ifilimu ehlanzekile isakazwa phansi futhi imiphetho ilungisiwe.
Ukwelashwa kwezilimo eziyizigaxa ngaphambi kokutshala.
- Izilimo eziyizigaxa zamazambane zibekwe ngokucophelela kungqimba olulodwa kufilimu. Kulesi simo, kubaluleke kakhulu ukuthi ungawaphuli amahlumela.
- Ukusebenzisa isifutho noma umshanelo ofakwe ku-ejenti ekhethekile, amazambane acutshungulwa ngokucophelela bese evunyelwa ukuba ome.
- Ngemuva kwemizuzu engama-20-30, izilimo eziyizigaxa ziphendulwa ngokucophelela futhi zicutshungulwe ngakolunye uhlangothi.
- Emahoreni ambalwa emva kokufafaza, izilimo eziyizigaxa zamazambane zilungele ukutshalwa.
Ukucwiliswa esixazululweni
Le ndlela ayisebenzi kancane, kodwa ukuze isetshenziswe kuyadingeka ukuba nesitsha esifanelekile. Izilimo eziyizigaxa kumele zibe sekhambi isikhathi esithile ukuze ama-insecticide afakwe kuzo.
Ngemva kokuba amazambane acutshunguliwe omisiwe futhi atshalwe emithonjeni.
Imaphi amathuluzi asetshenziswa ukwelapha nezilimo eziyizigaxa
Izindlela namalungiselelo okwelashwa kwangaphambi kokutshala empeleni awahlukani nalawo asetshenziselwa ukwelapha izihlahla zamazambane.
amakhemikhali
Ama-insecticide akhethekile abhekwa njengeyona ephumelela kakhulu ekulweni ne-Colorado potato beetle. Izidakamizwa eziningi ziye zaduma kakhulu phakathi kwabantu.
Izindlela zokupheka zabantu
Kwabasekeli bezindlela zemvelo nezemvelo, kunezindlela eziningi zokwelapha zesintu ongazilungiselela kalula.
| Izidakamizwa | Ukulungiselela |
|---|---|
| I-decoction yezikhumba zika-anyanisi | Iphansi lebhakede lekhoba elomile lithelwa ngamalitha ayi-10 amanzi. Kuyadingeka ukubeka umthwalo ukuze i-husk ingantanti phezulu futhi igcizelele izinsuku ezi-2. |
| Ukufakwa Kwekhasi Le-Walnut Elihlaza | Thela u-2 kg wekhasi le-walnut eluhlaza namalitha ayi-10 amanzi bese ushiya izinsuku ezinhlanu. |
| Izinkuni noma umlotha wamalahle | Yenza uthuli lwezilimo eziyizigaxa. |
Yini engaba yingozi ukucubungula amazambane nezilimo eziyizigaxa
Lapho ucubungula izilimo eziyizigaxa, kubaluleke kakhulu ukulandela imiyalo, ngaphandle kwalokho inqubo ewusizo ekuboneni kuqala ingaba yingozi:
- Akunakwenzeka ukutshala izilimo eziyizigaxa eziphathwe endaweni efanayo minyaka yonke. Ngokuhamba kwesikhathi, amakhemikhali anganqwabelana emhlabathini, futhi ngemva kweminyaka embalwa, amazambane atshalwe kuleyo nhlabathi angase angakufanelekeli ukudliwa abantu.
- Lapho ucubungula izilimo eziyizigaxa, kubaluleke kakhulu ukubheka imithamo yezidakamizwa, ngaphandle kwalokho ukweqisa kwezinto eziyingozi kungangena kuma-tubers amancane.
- Ukucutshungulwa kwangaphambi kokutshala kwezilimo eziyizigaxa akufanelekile ezinhlobonhlobo zokuvuthwa kwangaphambi kwesikhathi, ngoba kufanele kudlule okungenani izinyanga ezimbili kusukela ngesikhathi sokucubungula kuya ekudleni amazambane.
isiphetho
Ukucutshungulwa kwangaphambi kokutshala kwezilimo eziyizigaxa kukhona kokubili okuhle nokubi, kodwa naphezu kwalokhu, kuthandwa abalimi abaningi. Uma inqubo yenziwa kucatshangelwa yonke imithetho nezincomo, khona-ke imibhede yamazambane izovikelwa ngokuthembekile ezifweni nasezinambuzaneni, futhi izinto ezinobuthi ngeke zithinte ukwakheka nokunambitha kwesitshalo.
