Uyazi ngesibulala-zinambuzane okuthiwa i-dimethoate? Lokhu kunamandla kakhulu ezinambuzaneni eziningi ezingaba imbangela yemonakalo ehlukile ezitshalweni ozikhula ezingadini zakho nasezivandeni zakho futhi isetshenziselwa kabanzi izici ezahlukahlukene ezikwenza uzuze kakhulu.
Phakathi kwalezi isikhathi eside sayo namandla ayo okuqothula inani elikhulu lama-ejenti angaphandle angadala izinkinga ezindaweni zakho zangaphandle. Kule ndatshana sizokutshela ukuthi iyini nokuthi isetshenziswa kanjani ngokukhethekile, ukuze ukwazi ukuhlola ukuthi ngabe lesi sibulala-zinambuzane esinamandla yilokho okudingayo ukugcina izitshalo ezisengadini yakho.
Kuyini i-dimethoate?
Uma usezweni lezitshalo, impela usuvele uyakwazi, ngoba i-dimethoate iyi- isibulala-zinambuzane esinamandla esisetshenziswa kabanzi ukuze kuqedwe izinambuzane ezingenakubalwa ezivame ukuthinta ngqo izitshalo ezahlukahlukene, nokuholela ekubhujisweni kwazo ngokuphelele.
Yingakho kusetshenziswa le khemikhali, okuyi Yakhiwa yinkampani yaseMelika ngo-1950. Umsebenzi wawo omkhulu njengesibulala-zinambuzane esinamandla silele ekubeni yisithiyo esibalulekile se- acetylcholinesterase, equkethe i-enzyme elawula ukusebenza okulungile kohlelo oluphakathi lwezinzwa zezitshalo.
Lesi sibulali zinambuzane sisetshenziswa kalula ezicutshini zezitshalo, ukuthola ukumuncwa nokusatshalaliswa okusheshayo ezimboza zonke izindawo zesitshalo, ukuze kuthi lapho isinambuzane sesinye isifo sisondela ekudleni amaqabunga, izimbali noma izithelo ezifanayo, zimunce leli khemikhali eliwubuthi elizoliqothula.
I-Dimethoate yamukelwa yizinhlangano zezolimo kuwo wonke amazwe omhlaba, lapho igunyazwe ukuthi isetshenziselwe inani elithile lezinhlobo zezinambuzane ezibekiwe.
Kepha lokhu akusho ukuthi awukwazi ukusebenzisa lesi sibulali zinambuzane kwezinye izinhlobo zezinambuzane ezingaziwa bese uthola imiphumela emihle. Impela ezindaweni ezahlukahlukene izonikwa amandla i- sebenzisa futhi ulawule ezinhlotsheni ezahlukene zezinambuzane, kepha ikakhulukazi e-European Union, ubukhulu nezimvume zokusetshenziswa kwayo kubekiwe kwaba ngokulinganayo.
Izinambuzane ezilawulwa nge-dimethoate
Kunezinambuzane ezingapheli ezingalashwa ngalokhu isibulala-zinambuzane esinamandlaPhakathi kwazo esingagqamisa: i-olive tree spider mite, olive tree borer, olive tree borer, orange cacoecia noma carnation miner, almond tree bug beet, cottony orange and vine mealybug, red mealybug of the citrus or citrus red louse, pink worm, njll .
Kumele kuqashelwe ukuthi lezi ngezinye zezinambuzane ezingasuswa ngalolu hlobo lwamakhemikhali nohlu luqhubeka nezinye izinhlobo eziningi nezinambuzane ezihlasela izitshalo ezahlukahlukene.
Umthelela wayo emvelweni
Ngokuphathelene nesiphetho semvelo se-dimethoate, lena inokuphikelela okuphansi emvelweni, kepha uma inokuphikelela okudumile emhlabathini, lapho kungatholakala khona cishe izinsuku ezintathu kulezo zindawo ezibonakala ngathi ziyana.
Ezindaweni ezomile kungaphikelela isikhathi esiyizinsuku eziyi-120. Noma kunjalo, lesi yisikhathi esilinganisiwe futhi ngokuvamile isikhathi salesi sibulala zinambuzane emhlabathini cishe izinsuku ezingama-20.
Emanzini omfula, dimethoate ingaqhubeka isikhathi esingaphezu kwesonto, kepha lokhu akusho ukuthi iphikelela isikhathi eside ezindaweni ngenxa yokuthi zinomswakama, ngoba emoyeni onomswakama kuzokwehliswa ngamakhemikhali izinqubo ze-oxidation ne-hydrolysis.
Ukwehlukaniswa kwemvelo kwayo emhlabathini kuzoncika ekuthambekeni kwayo. Lokhu kusho ukuthi ukonakala kuzoza ngokushesha okukhulu kuleyo nhlabathi lapho kune-alkaline pH. Emizimbeni enamanzi, ayivezi ukubophezela kuzidalwa, kwehlisa masishane izinqubo ezahlukahlukene zebhayoloji nezamakhemikhali, zisizwa nge-volatilization nezinqubo ze-hydrolysis.
