Ubuthi obuvela ku-Colorado potato beetle: 8 amakhambi afakazelwe
Sekuyiminyaka engaphezu kwekhulu abantu behlushwa ukuhlasela kwe-Colorado potato beetle. Lesi zinambuzane ezincane ezinemigqa singesinye sezinambuzane eziqinile neziyingozi kakhulu. Abalimi abanolwazi bamazi kahle futhi bayazi ukuthi indlela ephumelela kakhulu yokubhekana ne-Colorado potato beetle ukusetshenziswa kwamalungiselelo akhethekile.
Okuqukethwe
Yiziphi izinzuzo zokusebenzisa amakhemikhali
I-Chemistry evela eColorado - ngokushesha nangempumelelo.
Inzuzo enkulu amakhemikhali, ukusebenza kwawo. Ngemuva kokuthi izinto ezinobuthi ezenza amalungiselelo zingene emzimbeni wezinambuzane, zifa cishe ngokushesha. Ngakho-ke, ukucutshungulwa okuvamile kwemibhede yamazambane kunikeza umphumela omuhle kakhulu.
Nokho ukuhlanganisa okukodwa i-insecticide, kulula ukuyisebenzisa. Ezimweni eziningi, kwanele ukuhlakaza umuthi emanzini ngokusho kwemiyalelo futhi ucubungule izilimo eziyizigaxa zamazambane noma imibhede.
Izinhlobo zamakhemikhali zokulwa ne-Colorado potato beetle
Inqwaba yamakhemikhali okubhubhisa i-Colorado potato beetle ihlukaniswe yaba izinhlobo ezimbili: imikhiqizo yezinto eziphilayo kanye nezibulala-zinambuzane. Umehluko wabo omkhulu yizinto ezisebenzayo kanye nendlela isilokazane esenza ngayo emzimbeni.
I-Biopreparation
Amalungiselelo anjalo athandwa kakhulu phakathi kwabalimi, njengoba engenabungozi kubantu, izilwane, izitshalo kanye nomhlabathi.
Imikhiqizo yezinto eziphilayo isekelwe kuma-microorganisms abhubhisa izinambuzane.
Ububi bezidakamizwa ezinjalo ukungasebenzi kwabo ngokumelene ne-oviposition kanye nokunciphisa ukusebenza kahle ngokusetshenziswa njalo. Okudume kakhulu phakathi kwemikhiqizo yezinto eziphilayo kukhona.
Isibulala-zinambuzane
Amalungiselelo aqukethe izinto ezinobuthi ayingozi kakhulu, ngakho kufanele asetshenziswe kuphela lapho ezinye izindlela nezindlela zinganikezi umphumela oyifunayo. Lezi yizibulala-zinambuzane eziphumelela kakhulu futhi ezifakazelwe.
Imithetho yokusebenza ngamakhemikhali
Ukucubungula ngamalungiselelo akhethekile kungaba yingozi futhi lapho usebenza ngezinto ezinobuthi kubaluleke kakhulu ukulandela zonke izinyathelo zokuphepha ezidingekayo:
- Kufanele ufunde ngokucophelela imiyalelo futhi ulandele ngokuqinile lokho okulotshwe kuyo.
- Izingane, abesifazane abakhulelwe kanye nabantu abaphethwe izifo zokuphefumula akufanele baphathe noma babe seduze.
- Ngesikhathi sokucubungula, qiniseka ukuthi usebenzisa izinto zokuzivikela.
Sebenza emishinini yokuzivikela kuphela.
- Ngemuva kokuqeda umsebenzi ngamakhemikhali, kuyadingeka ukugeza izingubo kahle futhi ugeze.
- Iziqukathi nezifutho ezike zasetshenziswa ukuphatha ubuthi akufanele zisetshenziselwe ezinye izinqubo.
- Ngemuva kokufafaza ngamalungiselelo, kungenzeka ukuvuna emibhedeni kuphela ngemuva kwezinsuku ezingama-30-40.
- Ukwelashwa ngamakhemikhali kufanele kwenziwe kusihlwa noma ekuseni kakhulu, esimweni sezulu esipholile.
isiphetho
Ubuthi be-Colorado potato beetle ingenye yezindlela ezidume kakhulu zokulawula izinambuzane. Izinto ezinobuthi zithengiswa cishe yonke indawo endaweni yomphakathi futhi ububanzi bezidakamizwa ezinjalo buhluke kakhulu.
Kodwa uma usebenzisa amakhemikhali, umuntu akufanele akhohlwe ukuthi izinto ezinobuthi ezakha ukwakheka kwazo zingaba yingozi hhayi ezinambuzaneni kuphela, kodwa nakumuntu ngokwakhe. Ngakho-ke, ukuhambisana nesilinganiso esifanele kanye nemithetho echazwe emiyalweni kuyimfuneko lapho usebenza nabo.
