Ka la 2 Hlakubele, 2015, WHO e ntshitse lethathamo le ntjhafaditsweng la dibolaya-dikokwanyana le dihlahiswa tse kgothalletswang ho fafatsa ka tlung ho thibela le ho laola dikokwana-hloko tsa malaria, ho kenyeletswa le pyrimiphos-methyl. Bakeng sa pyrimidinhos methyl, Actellic (Baoan Valley) e sebedisitsoe haholo dibakeng tse kenyeletsang temo, polokelo, bophelo bo botle ba setjhaba le meru ho tloha ka 1970. Khomishene ya FAO/WHO Codex Alimentarius e sisintse hore masalla a pyrimidinhos-methyl a ke ke a baka dikotsi tsa nako e telele ho batho; Mokgatlo wa Matjhaba wa Maritime o kgothaletsa hore pyrimidinhos-methyl e ka sebediswa dikepeng; Mokgatlo wa Brithani wa ho Bitsa o amohetse pyrimiphos-methyl E sebediswang bakeng sa taolo ya dikokonyana polokelong ya harese e sebediswang bakeng sa ho besa; mokgatlo wa dijo tsa diphoofolo o tiisitse hore ebang ke dijo-thollo tse phekotsweng ka pyrimidinhos pele kapa ka mora kotulo, e ka fepuwa diphoofolo ka ho toba; tekanyo e kgothaletswang ya pyrimidinhos e sebedisetswa ho phekola dihlahiswa tsa temo E sebedisitswe ka botlalo mme e amohetswe kgwebong ya matjhaba ya dinaha tse ngata.
