Hoʻolauna

ʻO ka lāʻau lapaʻau e pili ana i kahi ʻano insecticide e pepehi i nā mea ʻino, i hoʻohana nui ʻia no ka mālama ʻana i nā pests mahiʻai a me nā pōʻino olakino kūlanakauhale.E like me nā pipi, nā nalo, nā ʻōpala, nā ihu, nā ʻauʻau, a me nā mea ʻino ʻē aʻe he 10000.He moʻolelo lōʻihi ka hoʻohana ʻana o nā insecticides, ka nui, a me nā ʻano like ʻole.

Hoʻokaʻawale

Nui nā kūlana hoʻokaʻawale no nā pesticides.I kēia lā, e aʻo mākou e pili ana i nā pesticides mai nā ʻano o ke ʻano o ka hana a me ka toxicology.

Ma muli o ke ʻano o ka hana, hiki ke hoʻokaʻawale ʻia nā pesticides penei:

① ʻO ka ʻōpū ʻawaʻawa.Komo ia i loko o ka ʻōnaehana hoʻoheheʻe ʻana ma o ka waha o ka pepeke a loaʻa ka hopena ʻona, e like me Metrifonate.

② Hoʻokaʻaʻike i nā mea pepehi kanaka.Ma hope o ka hoʻopili ʻana me ka epidermis a i ʻole nā ​​mea hoʻohui, komo ia i loko o ke kino o ka pepeke, a i ʻole e hoʻopōʻino i ka papa wax o ke kino o ka pepeke, a i ʻole ke poloka i ka valve e pepehi i nā pests, e like me pyrethrin, mineral oil emulsion, etc.

③ Mea hoʻohuhū.Hoʻokumu ʻia ka mahu e ka volatilization o ke kinoea ʻona, ka wai a i ʻole ka paʻa i nā mea ʻino a i ʻole nā ​​germs, e like me Bromomethane.

④ Inhalation o nā lāʻau lapaʻau.Hoʻopili ʻia e nā hua kanu, nā aʻa, nā ʻōpala, a me nā lau a lawe ʻia i ka mea kanu holoʻokoʻa, i loko o kekahi manawa, komo ka pathogen a i ʻole kāna mau metabolites i hoʻāla ʻia i loko o ke kino pepeke ma ka ʻai ʻana i ka ʻiʻo o ka mea kanu a i ʻole ka omo ʻana i ka wai o ka mea kanu, e pāʻani ana i kahi hana ʻawaʻawa. , e like me ka dimethoate.

Wahi a nā hopena toxicological, hiki ke hoʻokaʻawale ʻia nā insecticides i:

① Nā lāʻau neurotoxic.Hoʻohana ia i ka ʻōnaehana nerve o nā pests, e like me DDT, parathion, carbofuran, Pyrethrin, etc.

② Nā mea hana hanu.Kāohi i nā enzyme hanu o nā pests, e like me ka cyanuric acid.

③ Nā mea hana kino.Hiki i nā ʻaila ʻaila ke hoʻopaʻa i ke kīpē o nā pests, ʻoiai ʻo ka pauda inert hiki ke hoʻopau i ka ʻili o nā pests a make lākou.

④ Nā insecticides kiko'ī.Ke hoʻoulu nei i nā hopena physiological ʻino o nā pests, e like me nā repellents e mālama i nā pests mai nā mea kanu, nā mea hoʻowalewale e hoʻowalewale i nā pests me ka moekolohe a i ʻole ka maunu, nā antifeedants e kāohi i ko lākou ʻono a ʻaʻole e hānai hou, e alakaʻi ana i ka pōloli a me ka make, nā mea hana sterile e hana i ka hana hānau makua. e hoʻopilikia i ka ulu ʻana, ka metamorphosis, a me ka hana hou ʻana o nā mea ʻino.

Dhoʻoulu ʻanaDkuhikuhi

① Hoʻomaka ka hoʻololi ʻana i ke ea o ka honua i nā hana o nā pest a me nā maʻi, a laila e alakaʻi i ka hoʻonui ʻana i ka hoʻohana ʻana i ka pesticide.I ka hana mahiʻai, pili loa ka hanana ʻana o nā pests a me nā maʻi i ka hoʻololi ʻana i ke aniau.Inā maikaʻi ʻole ke ʻano o ke aniau no ka ulu ʻana o nā pests a me nā maʻi, e hoʻemi nui ʻia ke kiʻekiʻe o ka hiki ʻana mai o nā pests a me nā maʻi, a laila e hōʻemi i ka hoʻohana ʻana i nā pesticides.

② Ke hoʻomau nei nā Insecticides i ke kūlana koʻikoʻi i ka mākeke pesticide honua, me ʻekolu ʻano nui o nā pesticides, ʻo ia hoʻi nā insecticides, fungicides, a me nā herbicides, ʻo ia nā mea pāʻani nui i ka mākeke pesticide honua.I ka makahiki 2009, ua helu ʻia nā insecticides no 25% o ka mākeke pesticide honua, me ʻAmelika ʻAmelika a me ʻEulopa e mālama nei i ka māhele mākeke nui loa, e helu ana ma kahi o 70% o ka mākeke holoʻokoʻa.

③ Ke hoʻomau nei ka hoʻomohala ʻana o ka ʻoihana pesticide honua, ke kū nei hoʻi ia i kahi ʻano o nā koi hou, ʻo ia hoʻi, ʻo ka hoʻohana ʻana i nā lāʻau pesticides i nā makahiki he kumu like ʻole o ka pollution i ke kaiapuni a me nā kānaka a me nā holoholona.No laila, ʻoi aku ka nui o nā koi kiʻekiʻe o ke kaiāulu honua no ka maikaʻi, haʻahaʻa haʻahaʻa, haʻahaʻa koena, a me ka pollution-free pesticides, ʻoi aku hoʻi i ka ʻoihana pesticide.
