Kāohi a me ka kaohi ʻana i ka palaho lau Curvularia ma nā lau nahele

Ka hoʻolaha ʻana a me ka pōʻino o ka palaho lau Curvularia
Ma muli o ka mālama ʻole o ka hoʻokele a me nā kumu ʻē aʻe, ulu ka lau nahele i kahi ʻano paʻakikī a maikaʻi ʻole hoʻi i ka maʻi. Ma waho aʻe ohoʻopili i nā mauʻuo ka ʻohana liʻiliʻi o Artemisia, e hoʻopili ʻo Curvularia i nā mauʻu o ka ʻohana liʻiliʻi o Pooideae, e like me ka bluegrass, meadow bluegrass, fine-leaved fescue, Canada bluegrass, ryegrass, a pēlā aku.

Pōʻino: He nāwaliwali ka lau nahele i maʻi ʻia, he lahilahi, a he mau kiko mauʻu make ʻano ʻē. He lahilahi a pōkole nā ​​kolamu mauʻu i loko o nā kiko mauʻu make, a ʻike ʻia he hina a make. Hoʻololi nā lau maʻi o ka bluegrass meadow a me ka fescue lau maikaʻi mai ka melemele a i ka ʻeleʻele mai ka piko a i ke kumu, a laila i ka hina, a hiki i ka make ʻana o ka lau holoʻokoʻa. Hoʻokumu nā ʻano pathogens like ʻole i nā hōʻailona like ʻole. No ka laʻana, i ka wā e hoʻopilikia ai ʻo Curvularia crescentus i ka bluegrass meadow, he oval a fusiform paha nā ʻeha ma nā lau maʻi, he hina ka waena o nā ʻeha, he ʻeleʻele nā ​​​​​​mea a puni, a he mau halo melemele ma waho. Ke uhi ʻia nā lau me nā ʻeha, make lākou.
Nā kūlana no ka ma'i lau o Curvularia

Mahana: He mea maʻalahi ke hana ke hiki ke kiʻekiʻe ka mahana ma kahi o 30 degere i kahi kaiapuni haʻahaʻa kiʻekiʻe.

Nā mea o ka maʻi: E hoʻopili i ka mauʻu e ʻike nei i nā pilikia wela kiʻekiʻe a i ʻole nā ​​​​​​hoʻōki ulu ma muli o ke wela kiʻekiʻe. Mauʻu, nā mea kanu cereal like ʻole, a me nā nāhelehele mauʻu. ʻO nā lau nahele i ulu maikaʻi ʻole ʻia, mālama maikaʻi ʻole ʻia, a me nā lau nahele i ulu nāwaliwali. Hiki ke loaʻa i nā wahi pulu a me nā mea hoʻoulu naikokene nui.

ʻAno o ka laha ʻana: Hoʻolaha me ka makani a me ka ua.

Ka pale ʻana a me ka mālama ʻana i ka pala o ka lau Curvularia

Nā hua: E koho i nā hua me ke kūpaʻa ikaika i nā maʻi a me nā mauʻu ʻaʻohe maʻi, a e hoʻohui i nā ʻano hua mauʻu like ʻole.

Ka lūlū ʻana a me ka hoʻoulu ʻanaE uhi pono i ka lepo i ka wā e lūlū ai, e makaʻala i ka mālama ʻana i nā mea kanu, e hoʻopili pono i ka mea hoʻomomona naikokene, e pale i ka hoʻopili nui ʻana i ka pūnāwai mua a me ke kauwela waena, a e hoʻonui i ka mea hoʻomomona phosphorus a me potassium.

Hoʻoinu wai: Pono e hoʻoinu wai i ke kakahiaka, pale i ka hoʻoinu wai i ke ahiahi, hoʻoinu wai hohonu a maikaʻi, hoʻēmi i ka hoʻoinu pinepine ʻana, a pale i ka hōʻiliʻili ʻana o ka wai ma ka lau nahele.

ʻOki ʻokiʻoki: E hoʻolohe i ke kiʻekiʻe o ka ʻokiʻoki ʻana, ʻo ka liʻiliʻi he 5 a 6 kenimika.

Kaiapuni: E wehe i nā lau koena o nā mauʻu maʻi a me nā mauʻu make i ka manawa ma hope o ke ʻoki ʻana, a e hoʻomaʻemaʻe pinepine i ka papa mauʻu make.
Nā hana lapaʻau no ka maʻi lau Curvularia

I ka lūlū ʻana, e kāwili i nā hua me ka nui kūpono o ka pauka pulu triadimefon a i ʻole 50% pauka pulu thiram. E pīpī i ka lau nahele me ka fungicide i ka manawa kūpono no ka pale ʻana a me ka kaohi ʻana i ka wā mua o ka maʻi.
