ʻO ka meaʻono ka meaʻai maikaʻi a maikaʻi , aia nāʻanoʻano he nui, he maikaʻi kēlā mea kēia mea ma konaʻano pono'ī. Eia naʻe, no ka hoʻomaʻamaʻa pinepineʻana o nā māla no ka maʻi o ka currant, ua hoʻopiliʻia nā lau. No ke aha e hiki ai kēia a me keʻano o ka hoʻopakeleʻana i ka mea kanu - ke aʻo nei mākou mai kēiaʻatikala.
Nā kumu o Curling Currant Lea
Aia kekahi mau ho'ākāka he aha ka lau iʻeleʻele aʻeleʻele paha. Hāʻawiʻia ka lau e nā aphids, aiʻole ma ka maʻi viral, a ma kekahi mauʻano,ʻo ka laupalapa, ka paukū a me ka'alekuma,ʻo ia ka mea hewa. No kēia mau meaʻoluʻoluʻole i keʻano kiko'ī.
ʻO ka hoʻoweliweliʻana o nā aphids
Hoʻopiliʻia nā'ōpoki'ōpala maʻamau e nā'ūlū e hānai i ka wai a lākou e hana. ʻO kaʻoi o ka hōʻinoʻana iʻoi aku ka laulā ma mua o kekahi. ʻO kaʻimiʻana i nā aphids he mea maʻalahi wale nō - e nānā wale ma lalo o ka lau, a eʻikeʻia he nui o kēia mau'īkoi liʻiliʻi. ʻO nā lālā o ka lauwili ka hopena o ka maloʻo waleʻana o nā'ōpihi e inu i ka wai. I ka manawa pinepine, e kinai ka lau i ka melemele i ka manawa mua, a laila e pale i luna. Pono pono e hakakāʻaʻole wale me nā aphids, akā, me nā kuʻi.
He aha ka hana e hana ai inā hoʻopiʻiʻia nā lau lau ma muli o nā aphids:
- E kāpīpī i ka mea kanu i ke kakahiaka mua o ka hoʻomaʻemaʻeʻana i nā lau me kahi wai o nitrafen;
- Ma mua a ma hope paha o ka uluʻana, e mālama me ka carbophos;
- e kāpīpīʻia me ka wai huihuʻi e hakakā ai i nā mea makua
Ka uku hōʻoia
He'ōmeʻomaʻo'ōmaʻomaʻo a me ka mohala e hiki ke luku i 80% o nā lau. E hoʻomaopopo he kumu maʻalahi ke kumu i ka laulā - ua haʻalele lākou i nā lau i hoʻohuiʻia a'ōwiliʻia i loko o ka mauʻu. Aia kekahi mau hanana o ka uluʻana o kēia mau'ōpū: nā hua pālalaʻula-'ōmaʻomaʻo, nā'ōpūʻeleʻele a me nā anuhe'ōmaʻomaʻo'ōmaʻomaʻo a me nā papalina momona. I kēlā me kēia hihia, ponoʻoe e hoʻomaka koke i ka lāʻau lapaʻau, ma ka hanaʻana i ka mea kanu me ka carbophos ma mua o ka puaʻana a ma hope paha o kaʻohiʻana o kaʻohi. Pono eʻokiʻia nā lau lūlū a puhiʻia i waho o ka pūnaewele.
ʻO Anthracnose
I loko o ka anthracnose, ka lau o ka lau lauwili me ka pale. ʻO ka maʻi keʻano koʻikoʻi a kauʻia ma nāʻano non-chernozem i loko o nā kumulāʻau he nui. ʻO ka maʻi e hoʻopili i ka pae honua honua a pau o ka mea kanu,ʻike mua ia e like me nā meaʻulaʻula i nā lālā'ōpiopio, a laila e hoʻonui, e hoʻoluli, e hoholaʻia ma luna o kaʻala o ke kino, e lilo i keʻokeʻo me ka loleʻulaʻula. Hoʻopilikia ka maʻi i ka uluʻana a me ke uluʻana o nā kumu liʻiliʻi a me kāna hua.
He aha ka mea e pīpī i nā lau lau, inā e hoʻohuliʻia lākou mai ka anthracnose:
- i ka pūnāwai mua, nā mea kanu kahe me kahi wai o Bordeaux wai (2-3%);
- hiki iāʻoe ke'ōpala i ka 0.4% me ka hoʻokuʻuʻia o kahi kīʻaha.
ʻO ka māmā
ʻO ka Powdery mildew he maʻi ia e pili ana i ka māhele'āina o nā mea kanu,ʻaʻole waleʻo kahi kanu, akā, no nā hihiu hoʻi. Ma kēiaʻano,ʻo nā wana a pau, nā lau, ua uhiʻia ka pahu i kahi kapa keʻokeʻo, kahi hana mua, a me - mealy, hue hina-grayish. Ke hoʻopilikia nuiʻia ka maʻi, ua pupuhi nā'ōpuʻu, ua palahalaha nā lau,'ōwili, ulu ka ulu, a laila e hāʻule nā lau.
He aha ka hana e hana ai ināʻo ka lau ka lau o ka lau e like me ka paukū lūlū:
- e kāpīpī ma hope o ka napoʻoʻana o ka lā me kahi waiāwaliwali o ka Uurea
- hiki iāʻoe ke hoʻohana i kahi hoʻolālā lepo 1 sulfur;
- hana iā Topaz.
E hana hou i kāu hana e hana houʻia iʻelua manawa me ka manawa o ka 7 a 10 mau lā.
