ʻO kahi maʻiʻino e pili ana i ka Rose Family
He aha ka mea e hana ai kekahi e mālama ai i ka "hōʻailona ahi" ma luna o nā kumu lāʻau Bradford? A he aha keʻano o kēia pilikia weliweli? ʻAʻole hiki i kekahi maikaʻi ke hele mai,ʻoiaʻiʻo, mai kahiʻano e hui pūʻia kēlā mau hua'ōlelo palahalahaʻelua, ua hāʻawiʻia ka mana hoʻoneʻe o ke ahi a me ka manawa i hoʻohaʻahaʻaʻia e ka "hōʻino" (e like me keʻano o keʻano o ka pōʻino, ka luku, ka hōʻino, a me ka hōʻeha).
Ua kākau ka mea heluhelu i ka nīnauʻana e pili ana i kēia pilikia wale nō.
"Ua loli nā pua ma kuʻu mau Bradford i kēia makahiki, a ua make ka ulu houʻana," i kākau aiʻo ia. "Ua make nā wēlau o nā lālā, he aha ka hewa, he maʻiʻino kēia, a inā pēlā, pehea wau e hana ai?"
He aha ke ahi ahi, pololei?
ʻO nā hōʻailona i hōʻikeʻia e nā mea heluhelu e hōʻike ana i ka uila ahi. Ma mua o kou aʻoʻana i ka mea e hana ai e pili ana i ia mea, e nānā pono kākou i keʻano o ia mea.
ʻO ka'ōpū ahi (kekahi mau manawa i hua'ōlelo hoʻokahi hoʻokahi) he maʻi bacteria. ʻO keʻano o ka huapalapa e hoʻokauʻia ai ka inoa Latin o Erwinia amylovora . Hoʻopilikia ka maʻi i nā lāʻau a me nā ulu lāʻau i kaʻohana rose. Ināʻaʻoleʻoe i hoʻokomoʻia i kaʻohana rose , eʻoluʻoluʻoeʻaʻole e pili wale kēia hoʻohālikeʻana i nā mea ulu lāʻauʻala mai kahi āu iʻike ai ma ka wā'ōpiopio. ʻO kēia mau'ōlaʻa a me ka lāʻau pīlā, no kēiaʻohana kanu mea kanu.
ʻAʻole wale i ka uluʻana o nā lāʻau pear no kā lākou huaʻai eʻaʻai i ka hōʻailona ahi, akā,ʻo nāʻano nani e like me nā lāʻau ''Aristocrat'.
ʻOiaiʻo ke kumu o ka paleʻana i nā lāʻau o Bradford i ke ahi welaʻana,ʻaʻole ia i keʻakeʻaʻole i ka palekana o ia mau mea (i ka nui o ka piʻiʻana o ke ahi). ʻO nā puaʻeleʻele ka hōʻailona o ka'ōʻana o ke ahi. Hiki i ke kino o ke kino ke lele i lalo i kahi lālā a hana i kahi kāhili; hiki iā ia ke pepehi i ka lālā a iʻole nā mea likeʻole.
E noʻonoʻo, no ka mea, aia ka bacteria ma ke kumu o ka pilikia,ʻo ka hoʻomaluʻana me kahi fungicideʻaʻole ia e hopena i ka'ōʻana o ke ahi.
He aha e hana ai e pili ana i ke ahi ahi ma Bradford Pear Trees
ʻO ka mālamaʻana i keʻano o nāʻano ahi-ʻano ahi-nui loa, e like me ka University of California. Ke kākau nei lākou, "ʻO nā hua kupa wale nā mea i loaʻa i nā mea hale no ke kāohiʻana i ka hōʻailona ahi, aʻaʻole lākou e hāʻawi i ka mana kūpono me nā polokalamu lōʻihi." Hōʻike lākou e hiki ke hanaʻia kekahi maikaʻi ma kahi nāwaliwali o Bordeaux a iʻole ke keleawe'ē aʻe ua hoʻohanaʻia ka huahana i nā manawa he nui ka puaʻana o ka pua, "akā,'ōlelo lākouʻaʻole kēia e hōʻalo i kāu pilikia ahi me kaʻole.
E nānā i kahi lāʻau o Bradford ināʻikeʻia e ke ahi. Hiki ke mālamaʻia ka maʻi inā loaʻa iā ia i ka manawa. Hiki ke huli, kūpono, a hoʻokuʻu i nā lālā i hoʻopiliʻia i ka hoʻolahaʻana o ka mea maʻi. Ma keʻano he mauʻoihana, hiki i nā kānaka kelepa ke komo i nā'ōkuhi i hikiʻole i ka mea kūʻai hale noho ke loaʻa. Hiki ke kohoʻia e hoʻohana i kahi bactericide (me streptomycin sulfate) ma luna o kāu kumu lāʻau Bradford e hoʻoponopono ai i ke ahi.
