Solution is undertaken using scientific fruit plant propagation and conducting innovative top-wedge grafting of (tree tomato) tamarillo (Solanum betaceum) terminal bud stick scion into its poisonous wild relative  bug weed rootstock tolerant to drought and resistant to soil borne diseases and pests as well as having longer roots  than tamarillo and stronger ones. Both plants belong to Solanaceae plant family, hence grafting the two plants is compatible and methodology transforms bug weed (Solanum mauritianum) as required. This innovation has therefore created food, agriculture and economic opportunities by using grafting methodology to transform the poisonous bug weed into agro biodiversity resources problem globally. Innovation is expected to contribute to feeding the ever growing world population that is expected to be nine billion by 2050.
