ʻO nā fungicides soya: ka mea āu e ʻike ai

Ua hoʻoholo wau e hoʻāʻo i nā fungicides ma nā soya no ka manawa mua o kēia makahiki. Pehea wau e ʻike ai i ka fungicide e hoʻāʻo ai, a i ka wā hea wau e hoʻopili ai? Pehea wau e ʻike ai inā he kōkua?

ʻO ka paneli aʻoaʻo aʻoaʻo hōʻoiaʻiʻo Indiana e pane ana i kēia nīnau e pili ana iā Betsy Bower, Ceres Solutions, Lafayette; Jamie Bultemeier, agronomist, A&L Great Lakes Lab, Papu Wayne; a ʻo Andy Like, mea mahiʻai a me CCA, Vincennes.

Bower: Nānā e koho i kahi huahana fungicide me nā ʻano hana o ka hana e hoʻopili ʻia ma kahi o triazole a me strobiluron. Hoʻopili pū kekahi i ka mea hana hana SDHI hou. Koho i kahi hana maikaʻi ma ka mahele lau frogeye.

ʻEkolu mau manawa o ke kahua soybean e kūkākūkā ka nui o nā poʻeLoaʻa nā pōmaikaʻi a me nā maikaʻi ʻole i kēlā me kēia manawa. Inā he mea hou wau i ka hoʻohana ʻana i kahi fungis soybean, e māka wau i ka pae R3, ke hoʻomaka wale nā ​​pods e hana. I kēia wā, loaʻa ʻoe i ka uhi maikaʻi ma ka hapa nui o nā lau i ka pale.

Ua lohi ka noi R4 i ka pāʻani akā hiki ke maikaʻi loa inā loaʻa iā mākou kahi makahiki maʻi haʻahaʻa. No kahi mea hoʻohana fungicide manawa mua, manaʻo wau ʻo R2, pua piha, hiki wawe e hoʻopili i kahi fungicide.

ʻO ke ala wale nō e ʻike ai inā e hoʻomaikaʻi nei kahi fungicide i ka hua e hoʻopili i kahi kahakaha kikoʻī me ka ʻole o ka palapala noi i ke kula. Mai hoʻohana i nā lālani hopena no kāu kaha kaha, a e nānā pono e hana i ka laulā o ke kaha kikoʻī ma ka liʻiliʻi o ka nui o kahi poʻo poʻohiwi a i ʻole kahi pōʻai hui.

Ke koho ʻana i nā fungicides, e nānā i nā huahana e hāʻawi i ka kaohi o nā maʻi i loaʻa iā ʻoe i nā makahiki i hala aku nei i ka nānā ʻana i kāu māla ma mua a i ka wā e hoʻopiha ai ka palaoa. Inā ʻaʻole loaʻa kēlā ʻikepili, e nānā i kahi huahana ākea ākea e hāʻawi i nā ʻano hana ʻoi aku ma mua o hoʻokahi.

Bultemeier: Hōʻike ka noiʻi i ka hoʻihoʻi nui loa o ka hoʻopukapuka kālā no kahi noi hoʻokahi o nā hopena fungicide mai kahi R2 hope i ka noi R3 mua. E hoʻomaka i ka māka ʻana i nā māla soya ma ka liʻiliʻi i kēlā me kēia pule e hoʻomaka ana i ka pua. Kālele ʻana i ka maʻi a me ka ʻume insect a me ka pae ulu e hōʻoia i ka manawa kūpono noi ʻoi loa fungicide. Hoʻomaopopo ʻia ʻo R3 ke loaʻa kahi pod 3/16-inch ma kekahi o nā piko ʻehā o luna. Inā ʻike ʻia nā maʻi e like me ka puna keʻokeʻo a i ʻole ka lau lau frogeye, pono ʻoe e mālama ma mua o R3. Inā kū ka lāʻau ma mua o R3, pono ʻia kahi noi ʻelua ma hope ma ka piha o ka palaoa. Inā ʻoe e ʻike i nā aphids soybean nui, stinkbugs, beetles leaf beetles a i ʻole Japanese beetles, aʻoaʻo paha ka hoʻohui ʻana o kahi insecticide i ka noi.

E waiho pono i kahi kaha i hana ʻole ʻia a hiki ke hoʻohālikelike ʻia ka hua.

E hoʻomau i ka mākaʻikaʻi ʻana i ka māla ma hope o ka noi ʻana, e kia ana i nā ʻokoʻa o ke kaomi maʻi ma waena o nā ʻāpana i mālama ʻia a mālama ʻole ʻia. No nā fungicides e hāʻawi i kahi hoʻonui i ka hua, pono e loaʻa kahi maʻi no ka mālama ʻana i ka fungicide. Hoʻohālikelike i ka ʻaoʻao ma ka ʻaoʻao ma waena o ka mālama a mālama ʻole ʻia ma mua o hoʻokahi mahele o ke kahua.

E like me ka mea maʻamau, ʻo ka noi fungicide a puni ka pae ulu R3 e hāʻawi i nā hopena hua maikaʻi. ʻO ka ʻike ʻana i ka fungicide maikaʻi loa e hoʻohana ai ma mua o ka hoʻomaka ʻana o ka maʻi he paʻakikī. I koʻu ʻike, ua hana maikaʻi nā fungicides me ʻelua ʻano o ka hana a me ka helu kiʻekiʻe ma ka lau lau frogeye. ʻOiai ʻo kou makahiki mua kēia me nā fungicides soybean, e haʻalele wau i kekahi mau kaha kaha a i nā mālamana hoʻokaʻawale e hoʻoholo i ka hana o nā huahana.
