ʻUala ʻEulopa Hope Blight: He aha ke ʻano o ka nānā ʻana i ka Genotype 2025 no ka hoʻokele kū'ē

He heluna pathogen e loli nei

ʻIke ka nānā ʻana i ka palaho hope o ʻEulopa i nā loli i ka heluna o Phytophthora infestans. Ma nā hopena no 2025 i hoʻokuʻu ʻia i Iulai 2026, ua hōʻike ʻo EuroBlight ma mua o 1,700 mau laʻana genotyped mai 27 mau ʻāina ʻEulopa. Ua hōʻike ʻo EU36 ma kahi o 31%, EU43 ma kahi o 10% a me EU46 ma kahi o 7% o kēlā mau laʻana.

He aha ka hana a me ka manaʻo ʻole o nā helu

Hōʻike kēia mau pakeneka i ka haku mele ʻana o ka heluna pathogen i laʻana ʻia. ʻAʻole lākou he pakeneka o nā mahina ʻai i loaʻa i ka maʻi a i ʻole nā ​​ana o ka nalowale o ka mea kanu. Hoʻopili ke aniau, ka ikaika hōʻike a me ke ʻano honua laʻana i nā hoʻohālikelike ma waena o nā makahiki. ʻOiai i nā kau me ka haʻahaʻa o ke kaomi holoʻokoʻa, hiki ke ulu kahi maʻi ahulau hōʻino ke makemake nā kūlana i ka maʻi.

Hoʻokele kū'ē

Hōʻike kekahi mau heluna pathogen i nā ʻokoʻa i ka ʻike ʻana i ka fungicide, e hana ana i kahi pono no ka mālama pono ʻana i nā ʻano hana. Pono ka hoʻokele maʻi e hoʻohui i ka nāwaliwali o ka cultivar, volunteer kaohi, wānana ʻana i ke aniau, ka nānā ʻana i ka manawa kūpono a me nā lāʻau lapaʻau i ʻae ʻia e ka wahi. ʻAʻole nā ​​inoa genotype wale nō ka hōʻike o ke kū'ē ʻana i kahi mea hana kūikawā; pono nā hōʻike susceptibility.

E nānā ana i mua

Ma mua o ke kau ulu e hiki mai ana, pono nā kākā'ōlelo a me nā mea mahiʻai e nānā hou i ka papahana palekana ma mua, e nānā i nā hopena o ka nānā ʻana kūloko a hahai i nā lepili o kēia manawa a me nā ʻōlelo aʻoaʻo no ka hoʻokele kūʻē.
