4. Ho molemo ho eketsa 0.5-1.5 dikgerama tsa DMPT nakong ea sehlaha ho hohela litlhapi ka potlako sehlaheng.Ha ho lokisoa bait, karolo ea peresente ea lijo tse omileng ke 1-5%, ho bolelang hore ligrama tse 5 tsa DMPT le ligrama tse 95 ho isa ho tse 450 tsa likarolo tsa phepelo e omileng li ka tsoakoa ka ho lekana.

5. DMPT e ka qhibiliha ka metsing a hloekisitsoeng kapa a hloekisitsoeng, ebe e hloekisoa ho ea ho metsi a mangata a mangata ho kopanya le bait.Tšebeliso ea boits'oaro le boits'oaro bo ts'oana, e le hore ho ts'oana ha DMPT ka har'a bait ho be holimo.Ho feta moo, DMPT e ka kopanngoa le lisebelisoa tse tala tse entsoeng ka phofo ka thepa e tala ea bait ka ho li kenya ka mekotleng ea polasetiki e tiisitsoeng ka thata kapa mekotla ea sampole ebe e e sisinya pele le morao ho netefatsa ho kopanya ho feletseng le ho lekana.Joale, motsoako oa 0.2% oa tharollo ea metsi ea DMPT e ka eketsoa bakeng sa ho feto-fetoha.

Ho phaella moo, e le ho thibela ho kopanya le lits'ebetso tse ling tsa khoebo le ho fetola thepa le monko oa tsona, ho kgothaletswa hore metsoalle ea ho tšoasa litlhapi e leke ho sebelisa lihlahisoa tse hloekileng tsa lijo-thollo.Ha e le hantle, haeba lihlahisoa tse hloekileng tsa lijo-thollo li le sieo, li-baits tsa khoebo li ka boela tsa sebelisoa.

U ka pheha lijo-thollo tse entsoeng ka mahahapa tse entsoeng ka maiketsetso kapa bait.Ka mohlala, karo-karolelano ea khatello e phahameng ea DMPT ke e latelang: ligrama tse 5 tsa DMPT, e qhibilihisitsoeng pele ho limililithara tse 100 tsa metsi a hloekileng, e tsosoa ka ho lekana le ho qhibiliha ka ho feletseng pele e kopantsoe le ligrama tse 95 tsa bait e omileng, le karolo e setseng ea 0.2% ea dilute. tharollo e eketsoa ho ea ka tekanyo ea ho omella le ho koloba.(5%) Mohlala oa karo-karolelano e tlase ea DMPT: 5 dikgerama tsa DMPT, e qhibilihisitsoeng pele ho limililithara tse 500 tsa metsi a hloekileng, a hlohlelletsoa ka mokhoa o ts'oanang 'me a qhibiliha ka ho feletseng, a sebelisetsoang ho kopanya le ligrama tse 450 tsa bait e omileng,' me e tlatsitsoe ka 0.2% ea motsoako oa dilute. tharollo ho ea ka tekanyo ea ho omella le ho koloba.(1%) Ho lokisetsa tharollo ea DMPT dilute: 2 dikgerama tsa DMPT, pele e qhibiliha ka 1000 milliliters ea metsi (0.2%), e lokiselitsoeng e le tharollo ea dilute bakeng sa tšebeliso e tlang.Ho lokisoa ha DMPT le ho omella (1%): Nka ligrama tse 5 tsa DMPT le ligrama tse 450 tsa lisebelisoa tse ling tse tala 'me u li behe ka mokotleng oa polasetiki o koetsoeng hantle, u tsokele pele le morao, 'me u kopanye ka ho lekana.Ka mor'a ho li ntša, eketsa tekanyo e loketseng ea 0.2% DMPT dilute solution ho lokisa bait e hlokahalang.Ho lokisoa ha DMPT le bait e omileng (2%): Nka ligrama tse 5 tsa DMPT le ligrama tse 245 tsa lisebelisoa tse ling tse tala 'me u li behe ka mokotleng oa polasetiki o koetsoeng hantle, u tsokele pele le morao, u kopanye ka ho lekana. Kamora ho li ntša, eketsa e loketseng. palo ea 0.2% DMPT hlapolla tharollo ho lokisa bait e hlokahalang.Ho lokisoa ha DMPT le ho omella (5%): Nka ligrama tse 5 tsa DMPT le ligrama tse 95 tsa lisebelisoa tse ling tse tala 'me u li behe ka mokotleng oa polasetiki o koetsoeng hantle, u tsokele pele le morao, u kopanye ka ho lekana.Ka mor'a ho li ntša, eketsa tekanyo e loketseng ea 0.2% DMPT dilute solution ho lokisa bait e hlokahalang.

6. Ho molemo ho itokisetsa bait ea hau, kaha DMPT e ajoa ka mokhoa o ts'oanang ka har'a bait, ka tekanyo ea ho lokolloa ha junifomo ka metsing le nako e telele.Haeba e se e entsoe bait, e ka boela ea kolobisoa bosiu bo le bong ka tharollo e tsitsitseng ea DMPT ka tekanyo.
