Pesticides ākea ākea. Hiki i nā nematocides me ka hana fumigation ke hoʻoheheʻe i ka methyl isothiocyanate, formaldehyde a me ka hydrogen sulfide i loko o ka lepo, a loaʻa ka hopena pepehi i ka rhizoma nematode, stem nematode a me heteroderma nematode. Eia kekahi, loaʻa iā ia nā hopena insecticidal, bactericidal a me herbicidal, no laila hiki iā ia ke mālama i nā fungi lepo, nā pests lalo a me nā chenopodium weeds, e like me ka rhizoctonia potato, lepo polypteroptera insects, kowbeetles, May scarab larvae a pēlā aku. Ke hoʻohana nei i ka 98% particulate agent 750 ~ 900g/100m2 one one, 900 ~ 1050g/100m2 pālolo e like me ka mālama ʻana i ka lepo, hoʻolaha a noi ʻauwaha paha, hiki i ka Chemicalbook ke hoʻomalu i ka mea kanu a me ka maʻi nematode pīnī. Hiki ke ho'ohana 'ia ka pauda pulu 75% 1125g/100m2 no ka ho'omalu 'ana i ka ma'i nematode a'a 'uala.
ʻO ka lepo fumigant, ka methyl thioisothiocyanate nematocide, a no ka mālama ʻana i nā haʻi, nā mea ʻeha ma lalo o ka honua a me nā mauʻu, i ʻike ʻia hoʻi he hoʻopau wikiwiki. Hoʻopili ʻia ka huahana i loko o ka lepo e hana i ka methylaminomethyl dithiocarbamate, a ʻoi aku ka hana ʻana i ka methyl isothiocyanate. Hiki iā ia ke hoʻomalu pono i nā nematodes a me nā haʻuki lepo, e like me ka bacteria cataplexy, filarial bacteria, fusarium, a me nā mea ʻē aʻe, a hiki ke pale i ka ulu ʻana o nā mauhele he nui. He hopena maikaʻi kona ma luna o ka pulupulu melemele blight.
Kaʻina disinfection
(1) Ma mua o ka hoʻohana ʻana iā Dazomet, e hoʻomaʻemaʻe i nā aʻa o ka hua hope loa, a kau i ka mea hoʻomomona kumu e koi ʻia e ka mea kanu e hiki mai ana.
(2) E hōʻoia i ka hiki ʻana o ka wai o ka lepo ma kahi o 50-60% o ka nui o ka wai o ke kula, inā ʻaʻole i kūpono i ka maʻamau, hiki iā ʻoe ke hoʻokomo i ka wai i loko o ke kula; 3-5 mau lā ma hope o ka irrigation, e hoʻohana i ka mīkini e hoʻohuli a wāwahi i ka lepo e hōʻoia i ka permeability o ka lepo.
(3) I ka hoʻohana ʻana iā Dazomet, ʻo ka mahana kūpono o ka lepo he 12-18 ° C, a ʻaʻole hiki ke emi ka liʻiliʻi ma mua o 6 ° C.
(4) E hoʻohana i 25-40g o Dazomet i ka mika square o ka ʻāina. I waena o lākou, ʻo ka hoʻohana ʻana i ka kukumba, ka pepa ʻono, ka pepa ʻōmaʻomaʻo he 20-25kg / mu, ʻo ka hoʻohana ʻana i ka ʻōmaʻomaʻo tōmato he 25-30kg / mu, a ʻo ka hoʻohana ʻana i ka ʻōmaʻomaʻo strawberry he 15-20kg / mu.
(5) E hoʻopili pono i ka lāʻau lapaʻau ma luna o ka ʻili, a laila e hoʻohana i ka palau palau no ka mahi ʻai ʻana (ʻo 25-30cm ka hohonu), i pili pono ai ka piʻi ʻana o Dazomet me ka papa palau e hoʻokō ai i ka pono kiʻekiʻe. Inā kū koʻikoʻi ka nematode aʻa, pono ka hohonu o ka mahiʻai ʻana he 40cm, a pono ke kau ʻia ka palena kiʻekiʻe o ka hoʻohana ʻana i ka lāʻau.
(6) Ma hope o ka hoʻohana ʻana, hoʻoheheʻe ʻia ka wai ma ka ʻili e hana i ke kinoea disinfection (methyl isothiocyanate, formaldehyde a me ka hydrogen sulfide).
(7) E uhi i ke kiʻiʻoniʻoni (ʻaʻole e emi ka mānoanoa ma mua o 6 siliki), a laila hoʻopaʻa i ke kiʻiʻoniʻoni me ka lepo hou, mai hoʻokuʻu i ke kinoea disinfection, a mālama i ka mahana o ka lepo ma 10cm ma 20 ℃, pani ʻia ka disinfection ma kahi o 15-20 mau lā (i ke anuanu haʻahaʻa, pono e hoʻonui ʻia ka manawa fumigation).
(8) Ma hope o ka disinfection, wehe i ka kiʻiʻoniʻoni, a hoʻohana i ka palau rotary e hoʻoheheʻe i ka lepo, hoʻokuʻu i nā kinoea ʻawaʻawa i koe i ka lepo, maʻamau e ventilate no kahi o 15 mau lā (ke anuanu a pulu ka lewa, e hoʻolōʻihi i ka manawa ventilate, i ka wā e wela a maloʻo ka manawa, e hoʻemi i ka manawa ventilate).
(9) Hiki ke kanu ʻia nā hua ma hope o ka disinfection.
Mechanism o Dazomet boom
1. ʻO Dazomet kahi mea hoʻomaʻemaʻe fumigation lepo ākea ākea ākea me ka maikaʻi kiʻekiʻe, haʻahaʻa haʻahaʻa a ʻaʻohe koena.
2. Ke hoʻohana ʻia i ka lepo pulu, ua hoʻoheheʻe ʻia i loko o ka methyl isothiocyanate, formaldehyde a me ka hydrogen sulfide i loko o ka lepo, a pālahalaha koke i nā ʻāpana lepo, e pepehi pono ana i nā ʻano nematodes, pathogens, nā pests underground a me nā hua germination weed i ka lepo, i mea e hoʻokō ai i ka hopena o ka hoʻomaʻemaʻe ʻana i ka lepo.
3. Hoʻopili nui ʻia ka noi e ka wela o ka lepo a me ka haʻahaʻa a me ka hoʻolālā lepo, pono ka hoʻohana ʻana i ka mahana o ka lepo ma mua o 12 ° C, 12-30 ° C ka mea kūpono loa, ʻoi aku ka nui o ka haʻahaʻa o ka lepo ma mua o 40% (hiki ke hoʻopuʻi ʻia ka lepo i ka lima pinch lepo, hiki ke hoʻopuehu ʻia 1 mika kiʻekiʻe ma hope o ka hāʻule ʻana i ka honua e like me ke kūlana).
