Kule minyaka ilishumi idlulileyo abalimi baseIndiya bebetyalaBtumqhaphu – iindidi eziguquguqukayo eziqulethe iijini ezivela kwibhaktiriya yomhlabaBacillus thuringiensisiyenza ikwazi ukumelana nezinambuzane - ukusetyenziswa kwezibulali zinambuzane kuncitshiswe ubuncinane ngesiqingatha, uphononongo olutsha lubonisa.
Uphando lukwafumanise ukuba ukusetyenziswa kweBtumqhaphu unceda ukuthintela ubuncinci iimeko ezizizigidi ezi-2.4 zetyhefu yezinambuzane kumafama aseIndiya nyaka ngamnye, okonga i-US$14 yezigidi kwiindleko zempilo zonyaka.(BonaIndaloUkhuseleko lwangaphambili lweBtukuthathwa komqhaphu eIndiyaApha.)
Uphononongo lwezoqoqosho kunye nokusingqongileyoBtumqhaphu ngowona uchanekileyo ukuza kuthi ga ngoku kunye nophando lwexesha elide kuphelaBtabalimi bomqhaphu kwilizwe elisaphuhlayo.
Uphononongo lwangaphambili lucebise ukuba abalimi batyalaBtumqhaphu usebenzisa izibulali-zinambuzane ezincinci.Kodwa ezi zifundo zakudala azizange zenze ikhonkco le-causal kwaye bambalwa balinganise iindleko zendalo, ezoqoqosho kunye nempilo kunye neenzuzo.
Uphononongo lwangoku, olupapashwe kwi-intanethi kwijenaliI-Economics ye-Economics, kwenziwe uphando nabalimi bomqhaphu baseIndiya phakathi kowama-2002 nowama-2008. Ngoku iIndiya lelona lizwe livelisa umqhaphuBtumqhaphu oqikelelwa kwi-23.2 yezigidi zeehektare zokutyala ngo-2010. Amafama acelwa ukuba abonelele nge-agronomic, intlalo-qoqosho kunye nolwazi lwezempilo, kubandakanywa neenkcukacha zokusetyenziswa kwezitshabalalisi kunye nobuninzi kunye nohlobo lwetyhefu yezitshabalalisi ezifana nokukrala kwamehlo kunye nolusu.Amafama afumene ityhefu yezibulali zinambuzane anikezela ngeenkcukacha malunga neendleko zonyango lwe-heath kunye neendleko ezinxulumene neentsuku zokusebenza ezilahlekileyo.Uphando lwaluphindwa rhoqo emva kweminyaka emibini.
“Iziphumo zibonisa okoBtumqhaphu unciphise ngokuphawulekayo ukwenzeka kwetyhefu yezitshabalalisi phakathi kwamafama amancinci eIndiya,” lutsho olu phononongo.
Iingxoxo zoluntu malunga nezityalo ze-transgenic kufuneka zigxininise ngakumbi kwimpilo kunye neenzuzo zokusingqongileyo ezinokuthi "zibe zikhulu" kwaye kungekhona nje ingozi, isifundo songeza.
