Ma waho aʻe o nā mea laʻa a pau e pili ana i ka nohona o kaʻuala -ʻo ka'ōpala potato potatoʻo Colorado , he nui aku nā maʻi e hiki ai ke emi iho ka hua. ʻO kekahi mau maʻi e alakaʻi i ka hoʻohuliʻana i nā lau. E noʻonoʻo kākou e pili ana i kēia mau mea hōʻehaʻeha a me nāʻano hana e kū'ē iā ia ma ka mea.
ʻO nā lau o ka'ōlaʻi -ʻo nā kumu
ʻO ka hui mua o nā kumu he maʻi maʻi. Eia kēia mau mea:
- ʻO ka mosaic wrinkled. ʻO ka hopena e hele pūʻia me kahi lag i ka uluʻana, i kahi liʻiliʻi o nā kaha, ka wrinkles a me ka'ōwili o nāʻaoʻao o nā lau. ʻO ka hopena hope loa o ka ulu iki o nā uala.
- ʻO Mosaic Stripe. Keʻikeʻia ka maʻi i loko o ka'ō'ōʻana o ka uala. I ka manawa mua,ʻikeʻia nā wahiʻeleʻeleʻeleʻele - necrosis o nā lau mai kaʻaoʻao lalo, me nāʻehaʻoi aku iʻoi aku kaʻino a make ka lau, e kauʻia ma luna o nā aʻa. ʻO ke kumu, ua hoʻopiliʻia nā lau haʻahaʻa, ua mau ka'ōmaʻomaʻo. Hoʻonui kēia mau hōʻailona i ka wā o ka wela nui.
Pehea e hana ai i nā lālā o ka'ōlaʻi i ka hopena o ka maʻi:ʻo ka pale o kaʻaila mai nā maʻi viral ka wehe kokeʻia o nā mea maʻi me ko lākou mauʻano kanu, ka wela wela, kaʻohiʻana i ka manawa. E like me ka hua, nā huakai maikaʻi i kūʻaiʻia i nā hale kūʻai kūikawā pono e kohoʻia.
ʻO kaʻaoʻaoʻelua o nā kumu no ka'ānaiʻana i nā lau o kaʻuala he maʻi leʻaleʻa:
- ʻO Phytophthorosis -ʻaʻole e hoʻopili i nā lau wale nō, akā,ʻo ka pūpū a me ka'olola. ʻO ka mua, aia nā'āpanaʻeleʻele a me kaʻeleʻele ma luna o nā lau, ināʻaʻole i mālamaʻia ka mea kanu,ʻo ka'ōpoki i keʻokiʻoki e lilo iʻeleʻele aʻeleʻele. ʻO nāʻano o ka hakakāʻana,ʻo ia ka paleʻana,ʻo ka hoʻokomoʻana i nā mea i pono i ka lepo, i ka wā kanu e pono aiʻoe e hoʻoponopono i nā kumu lāʻau me nā papa hana lāʻau.
- ʻO Parsh - ke alakaʻi i ka'ōwiliʻana o nā lau, ke'ōmaʻomaʻo ke aʻa o kaʻuala a make koke. ʻO nā mea kanuʻoi aku iʻoi aku ka maʻi i kēia maʻi. Ma hope o ka'ōpuʻuʻana o kaʻohi,ʻaʻole e hoʻopili ka maʻi i nā mea kanu. No laila, maikaʻi ke kanuʻana i ka'ōlaʻau a ua hoʻomaopopoʻiaʻaʻole he lepo lepo ma nā kuahiwi. Mamua o ke kanuʻana, ua mālamaʻia ka'ōpū me kahi 1.5% o ka wai boric.
ʻO nā kumu i kū ai i ka lāla e pili ana i nā maʻi bacteria. ʻO ka mea nui, heʻeleʻeleʻeleʻele ia. Kūkulu ia i loko o ka mālamaʻana i nāʻano kanu, a me ka wā ulu o ka mea kanu. ʻO ka mua,ʻo nā lau apical ka pali i ka lelala, a laila ua lilo ke kumu o ke kapuaʻi iʻeleʻele a palaha. E kōkua wale nā mea palekana maʻaneʻi: ke kau muaʻiaʻana o nāʻano kanu, ka waihoʻana i loko o ka hopena o microelements - boron, keleawe sulfate, manganese a me ka zinc.
I kekahi manawa, heʻulaʻula kaʻuala a he lauwili ka lau a me ka wela nui, he aha ka mea e hana ai i kēia hihia: ka hoʻouluʻana a me nā lāʻau hoʻokipa, hiki iāʻoe ke nīpi i nā moena no ka mālamaʻana i ka wai ma ka lepo.
