ʻApida pulupulu
Nā hōʻailona o ka pōʻino:
Hoʻopili nā ʻāpala pulupulu i ke kua o nā lau pulupulu a i ʻole nā poʻo palupalu me kahi waha e omo ai i ka wai. Hoʻopilikia ʻia i ka wā kanu, ʻōwili nā lau pulupulu a lohi ka pua a me ka wā hoʻonohonoho ʻana o ka bowl, e hopena ana i ka pala lohi a me ka emi ʻana o ka hua; Hoʻopilikia ʻia i ka wā makua, ʻōwili nā lau o luna, ʻike ʻia nā lau waena he ʻaila, a mae a hāʻule nā lau o lalo; Hiki i nā ʻōpuʻu a me nā bolls i hōʻino ʻia ke hāʻule maʻalahi, e hoʻopilikia ana i ka ulu ʻana o nā mea kanu pulupulu; Hoʻoulu kekahi i nā lau hāʻule a hōʻemi i ka hana.
Ka pale ʻana a me ka kaohi ʻana i nā kemika:
10% imidacloprid 20-30g no ka mu, a i ʻole 30% imidacloprid 10-15g, a i ʻole 70% imidacloprid 4-6 g no ka mu, e pīpī like, hiki i ka hopena kaohi i 90%, a ʻoi aku ka lōʻihi ma mua o 15 mau lā.
ʻUmeke Punahele ʻElua-kiko
Nā hōʻailona o ka pōʻino:
ʻO nā ʻuku kolo ʻelua-kiko, i ʻike ʻia hoʻi he mau moʻo ahi a i ʻole nā kolo ahi, ua laha nui i nā makahiki maloʻo a ʻai nui i ka wai ma ke kua o nā lau pulupulu; Hiki ke hana mai ke kahua kanu a hiki i ke kahua makua, me nā hui o nā ʻuku a me nā ʻuku makua e ʻākoakoa ana ma ke kua o nā lau e omo i ka wai. Hoʻomaka nā lau pulupulu i hōʻino ʻia e hōʻike i nā kiko melemele a me keʻokeʻo, a i ka wā e ʻoi aku ka ʻino, ʻike ʻia nā ʻāpana ʻulaʻula ma nā lau a hiki i ka lau holoʻokoʻa e ʻeleʻele a mae a hāʻule.
Ka pale ʻana a me ka kaohi ʻana i nā kemika:
I nā kau wela a maloʻo, e hoʻohana i ka 15% pyridaben 1000 a 1500 mau manawa, 20% pyridaben 1500 a 2000 mau manawa, 10.2% avid pyridaben 1500 a 2000 mau manawa, a me 1.8% avid 2000 a 3000 mau manawa i ka manawa kūpono e pīpī like ai, a e uku ʻia ka nānā ʻana i ka pīpī like ma ka ʻili o ka lau a me ke kua e hōʻoia i ka pono a me ka hopena o ka kaohi.
ʻIlo Boll
Nā hōʻailona o ka pōʻino:
No ke kauoha Lepidoptera a me ka ʻohana Noctidae. ʻO ia ka mea ʻino nui i ka wā o ka ʻōpuʻu pulupulu a me ka wā boll. Hoʻopilikia nā larvae i nā wēlau palupalu, nā ʻōpuʻu, nā pua, a me nā ʻōpuʻu ʻōmaʻomaʻo o ka pulupulu, a hiki ke nahu i ka piko o nā kumu palupalu pōkole, e hana ana i ka pulupulu poʻo ʻole. Ma hope o ka hōʻino ʻia ʻana o ka ʻōpuʻu ʻōpio, huli nā bracts i melemele a hāmama, a hāʻule ma hope o ʻelua a ʻekolu paha lā. Makemake nā larvae e ʻai i ka pollen a me ka stigma. Ma hope o ka hōʻino ʻia ʻana, hiki i nā ʻōpuʻu ʻōmaʻomaʻo ke hana i nā kiko pala a paʻakikī paha, e hoʻopilikia nui ana i ka hua a me ka maikaʻi o ka pulupulu.
Ka pale ʻana a me ka kaohi ʻana i nā kemika:
He hopena maikaʻi ka pulupulu pale pepeke i ka lua o ka hanauna o ka pulupulu bollworm, a ʻaʻole pono ke kaohi. Ua nāwaliwali ka hopena kaohi ma ke kolu a me ka hā o ka hanauna o ka pulupulu bollworm, a pono ke kaohi i ka manawa kūpono. Hiki i ka lāʻau lapaʻau ke 35% propafenone • phoxim 1000-1500 manawa, 52.25% chlorpyrifos • chlorpyrifos 1000-1500 manawa, a me 20% chlorpyrifos • chlorpyrifos 1000-1500 manawa.
ʻO Spodoptera litura
Nā hōʻailona o ka pōʻino:
Hōʻuluʻulu nā larvae i puka hou mai a hānai i ka mesophyll, e waiho ana i ka epidermis luna a i ʻole nā aʻa koko, e hana ana i kahi pūnaewele pua a me nā lau e like me ke kānana. A laila hoʻopuehu lākou a hōʻino i nā lau a me nā ʻōpuʻu a me nā bolls, e ʻai nui ana i nā lau a hōʻino i nā ʻōpuʻu a me nā bolls, e pala ai a hāʻule paha. I ka wā e hōʻino ai i nā bolls pulupulu, aia he 1-3 mau lua ma ke kumu o ka boll, me nā nui o nā pores like ʻole a nui, a me nā ʻōpala pepeke nui i hoʻopili ʻia ma waho o nā lua.
Ka pale ʻana a me ka kaohi ʻana i nā kemika:
Pono e hāʻawi ʻia ka lāʻau lapaʻau i nā wā mua o ka larvae a kinai ʻia ma mua o ka wā ʻai nui ʻana. No ka mea, ʻaʻole puka mai nā larvae i ke ao, pono e pīpī ʻia i ke ahiahi. Pono ka lāʻau lapaʻau he 35% probromine • phoxim 1000-1500 manawa, 52.25% chlorpyrifos • cyanogen chloride 1000-1500 manawa, 20% chlorbell • chlorpyrifos 1000-1500 manawa, a pīpī like ʻia.
