ʻAʻole mea hou nā moʻolelo e pili ana i ka compost i nā metala koʻikoʻi mai ka wai ʻino a me nā herbicide ʻino e lele ana i ka lepo. I ka makahiki 2010, ua hoʻopuka ke Kulanui o Maryland Extension i kahi "Gardener's Alert! E makaʻala i ka compost a me ka manure i hoʻopōʻino ʻia i ka herbicide." Ua paʻi ka Ohio State University Extension i kahi pepa ʻoiaʻiʻo (PDF) e pili ana i kahi pesticide mau loa i loaʻa i loko o ka compost e pepehi ana i nā tōmato, eggplants a me nā mea kanu ʻē aʻe i ka pō, a me nā pī a me nā sunflowers.
Akā i kēia mau lā, ʻike ʻia e hoʻomaka ana ka poʻe māla e hoʻolohe i kekahi pilikia e pili ana i nā ʻāina potting pāʻoihana nui a me ka compost: ka hoʻokomo ʻana i nā pests a me nā maʻi i loko o kāu māla a i ʻole ka ulu ulu.
Aia nā hewa? Kaomi ma kā mākou hopena pest e nānā i nā kiʻi, nā wehewehe a me kahi papa inoa piha o nā huahana eco-friendly. Inā hoʻouka ia i nā mea kanu... e loaʻa iā ʻoe ma aneʻi! Loaʻa nā mea a pau mai nā aphids a i nā whiteflies.
ʻO ka lepo lepo, inā paha i loko o nā ʻeke a i ʻole i loko o nā ipu me nā mea kanu āu e kūʻai ai, he mea haumia ikaika. Ua ʻike ʻia no ka hoʻokomo ʻana i kahi aʻa aʻa i ʻike ʻole ʻia i loko o nā hale ʻōmaʻomaʻo a me nā kīhāpai ma ka ʻāina ma kahi ʻano maʻi ahulau. Ua ʻike ʻia nō hoʻi ka lawe ʻana i nā ʻūhā.
ʻO kekahi inoa inoa kaulana o ka lepo potting i kaulana loa no ka loaʻa ʻana o nā iniseti Hana pū me nā mea kūʻai aku Aia kahi ʻaoʻao i hoʻolaʻa ʻia no nā hoʻopiʻi.
Hiki iā ʻoe ke loaʻa nā hoʻopiʻi ma ka pūnaewele e pili ana i ka lepo maikaʻi ʻole a me ka compost mai nā hale kūʻai kaulahao nui i loaʻa i ka plastic a me nā ʻōpala ʻē aʻe.
He mea paʻakikī ke hahai i ka hoʻolaha ʻana o nā maʻi kanu a me nā maʻi fungal i loko o nā māla māla. Akā, ua manaʻo nui ʻia ka lepo lepo no ka laha ʻana o ka maʻi, ka ʻōpala a me ka maʻi ma kahi i hoʻohana ʻia ai. E kūʻai wale i ka maikaʻi maikaʻi loa mai nā mea āu e hilinaʻi ai.
Loaʻa pinepine nā aphids aʻa i ko lākou ala i loko o ka lepo kahi i aʻa ai nā mea kanu i loko. Hoʻopau kēia mau aphids i nā mea kanu i ka ikaika a me ka ikaika, e alakaʻi ana i ka hōʻino ʻana i ka hua a me ka pua. ʻO ke kūʻai ʻana i nā clones a me nā kahu hānai mai ka hilinaʻi, ʻoi aku ka maikaʻi o ka ʻāina, nā mea kanu i hiki iā ʻoe ke nīnau a puni he mea nui. E hōʻalo i nā huahana pēpē i kūʻai ʻia ma nā hale kūʻai nui a me nā hale kūʻai pahu nui.
He mea nui nō hoʻi ke kūʻai ʻana i nā ʻano mea hilinaʻi mai nā kumu hilinaʻi i ke kūʻai ʻana i ka manure a me ka compost. Hiki ke loaʻa nā lāʻau lāʻau koena i kēlā me kēia compost i hana ʻia mai nā ʻāpana lau nahele o ke kūlanakauhale a me nā ʻōpala ʻōmaʻomaʻo ʻē aʻe. Ua aʻo ke kūlanakauhale ʻo Seattle i kahi haʻawina koʻikoʻi i ka makahiki 1990 i ka wā i hoʻomaka ai ka compost i hana ʻia mai ka ʻōpala pā hale hana hou e pepehi i nā mea kanu mea kanu. Ua alakaʻi ʻia ka pilikia i ka pāpā ʻana i ka hoʻohana ʻana i ka clopyralid i nā lau.
I kēia manawa, loaʻa kekahi herbicide hoʻomau i ka compost - aminopyralid. Hoʻohana nui ʻia ʻo Aminopyralid i nā mauʻu a me nā wahi ʻai e pepehi i nā lau ākea. E like me ka clopyralid, hoʻouka ʻo ia i nā ʻano mea kanu lau lau ākea, me ka pī, ka pī a me nā ʻōmato. E like me ka clopyralid, hiki iā ia ke hoʻomau i ka lepo a me ka compost no nā mahina a i ʻole mau makahiki (ʻaʻole wikiwiki ka hana compost i kona decomposition).
ʻO Aminopyralid, i hana ʻia e Dow AgroSciences, loaʻa i loko o ka waiu waiu a me ka ʻai pipi. Hoʻohana nui ʻia kēia manure ma nā mahiʻai a me nā māla, akā hoʻopau pū ʻia i nā manures a me nā compost i kūʻai ʻia i nā māla home.
ʻO nā pilikia me ka pesticide, i hoʻokomo mua ʻia i ka makahiki 2005, ua hoʻomaka e ʻike ʻia ma ʻEnelani e 2008. Ua hoʻopaneʻe ʻo Dow i ka hoʻohana ʻana i ka spray a hiki i ka hoʻopuka ʻia ʻana o kahi ʻōlelo aʻo (wehe ʻia ka loulou).
Inā ʻaʻole hiki iā ʻoe ke kūʻai i ka compost a me ka lepo mai nā kumu kūlohelohe, ʻoi aku ka palekana o ka hana ʻana iā ʻoe iho. Ma kēia ala e ʻike pono ai ʻoe i ka mea e hana nei a me ka mea ʻole. ʻAʻole hiki ke kūʻai mau ʻia ka maluhia o ka naʻau.
