Kukuvadzwa kwemishonga yesora pambatatisi kunokonzerwa nekunaya kwemvura zhinji
Varimi kumaodzanyemba nekumabvazuva kweIdaho vakavhiringika nezviratidzo zvekuparara kwembesa kwakaitika muminda yavo yembatatisi zvichitevera kunaya kwemvura zhinji muna Chivabvu 2017. uye yero tsinga mumashizha - yakaonekwa muminda yedunhu spud ichitevera imwe mvura yaMay muna 2019.
Pam Hutchinson, weYunivhesiti yeIdaho mbatatisi yekurima mbatatisi Nyanzvi yekuwedzera masora, akaongorora uye akadzidza dambudziko - mvura zhinji isati yamera mbatatisi inogona kufambisa mishonga yesora yakadzika muvhu, umo inosvikika nyore nenhungirwa nemidzi yechubhu kupfuura mazuva ese. izvo zvinogonawo kukonzera kukanganisa kwezvirimwa. Neyeyedzero yake yekunaya kwemvura, Hutchinson anga achiyedza mana preemergence herbicides: Matrix, Outlook, Prowl H2O uye metribuzin.
"Ndaifanira kudzidza kuti ndezvipi zviratidzo zvingakonzerwa nemushonga wesora mumamiriro ezvinhu akadaro nekunaya kwemvura yakawandisa," Hutchinson akadaro. "Mumakore apfuura takatarisa uye takadzidza nezvekukuvara kwemishonga yesora mumamiriro ekukura."
Kunaya kwemvura yakawanda kusati kwamera kunogona kukonzera kusakura zvakanaka kwesora, sezvo mishonga yesora ichinyanya kudzika uye nekukasika nemuvhu kuti inyurwe nemasora nemidzi. Mumakore ekunaya, varimi vazhinji vembatatisi vaifanira kushandisa mishonga yesora yavakange vasina kuronga kushandisa.
Ngozi yekukuvadzwa kwemishonga yesora nekuda kwekunaya kwemvura yakawandisa inogona kunyanya kuoneka muminda ine ivhu rejecha, kuburikidza nemvura uye mishonga yesora isinganyungudike nemvura yakaita seMatrix ne metribuzin, inogona kupinda zvakadzika kudarika muvhu rakarema. Hutchinson anoshanda nevarimi vanorima ivhu rejecha uye vakagadzira zvirongwa zvekurwisa sora nemishonga isinganyanyikirwe nemvura inotangira kumera. Varimi vanokwanisa kuramba vakatarisa pakutanga kurwisa sora uye kutevera mishonga yesora mushure mekumera kana zvakakodzera.
"(Miedzo) yakasimbisa zvakanyanya zvekuti kana uine ivhu rejecha chairo uchange uine kufamba kwemishonga yesora yakaderera pane yaimbonzwisiswa kana mvura yakawandisa," Hutchinson akadaro.
Ritchey Toevs, murimi wembatatisi yeAberdeen uye aimbova sachigaro weIdaho Potato Commission, anotenda kuti zvidzidzo zvetsvagiridzo yaHutchinson zvakakosha kuvarimi, kunyangwe mumwaka wakajairika wekurima.
“Kana tiine zuva rine mhepo uye tisingawani mvura yakawanda uye mhepo ichiita kuti titadze kudiridza zvakanaka, tichawedzera mamwe maawa mashoma, totevedzera kunaya kwemvura zhinji, tisingazive kukanganisa kwayo. tinogona kunge tiri kukonzera,” Toevs akadaro.

Masora nemvura
Dr. Pamela JS Hutchinson, Potato Cropping Systems Weed Scientist weYunivhesiti yeIdaho kunze kwechiteshi cheAberdeen, akatsanangura kuti akanga achigamuchira nhare kubva kuvarimi vane hanya pamusoro pemvura yakawandisa uye kutonhora kunokonzera kukuvara kwembesa yembatatisi. Kunyangwe kunaya kuri chikomborero, kuwandisa kwemvura pamwe nekutonhora kwenguva refu nekushaikwa kwezuva zvave kuita kuti mishonga yesora iwanikwe nyore kutorwa nesora nembatatisi, asi kudzivirira mbatatisi kuti isagaye mamwe emishonga iyi nekukasira kurima zvakanaka. kushivirira.
"Chero chinhu chinodzikisira kukura kwembatatisi zvakare chinodzoresa mushonga wesora," anoti. “Kutonhora kwechando kunogona kuve dambudziko sezvo zvakaoma kuti chirimwa chembatatisi chibude nekukasira pasi pemamiriro ezvinhu aya. "
Zvisinei, pashure pokunge rwendo rwemasora rwapera, zuva rakaramba riri kunze uye makore akasara. Hutchinson akataura kuti kana ichinge yadziya uye zuva rapenya, kazhinji hazvitore nguva kuti zviratidzo zvekukuvadzwa kwesora pazvinomera zvembatatisi zvitange kunyangarika, nekuti mbatatisi dzinotanga kushingaira kukura uye dzinokwanisa kuputsa mishonga yesora. Muchokwadi, akacherekedza iyi nhevedzano yezviitiko muyedzo yake yekutsvagisa, pasina zviratidzo zvinoonekwa nekuvharwa kwemitsara uye pasina mhedzisiro patuber set, kuwanda kana goho.
Imwe yemiedzo yakataurwa naHutchinson parwendo rwemasora yaisanganisira mushonga wesora kubva kuSyngenta Crop Protection inonzi Reflex (fomesafen). Mhedziso yakasvika pakupera kwegore rapfuura ndeyekuti Reflex yakaisa pre-emera kumasora nembatatisi chete kana mukubatana nemishonga iyi yesora yaiwanzopa 90 muzana kana yakakura redroot pigweed uye ine mvere nightshade mwaka-refu kutonga.
Pre-musanganiswa we s-metolachlor uye metribuzin chete kana nekuwedzera metribuzin haina kupa yakakura kupfuura 85 muzana ine bvudzi nightshade control; zvisinei, nepo kuwedzerwa kwerimsulfuron kumusanganiswa kana kushandiswa gare gare, kutanga mushure mekumera kwakaguma ne 97 kusvika ku100 muzana kudzora kwesora iri.
Makwayana akajairwa kutonga neReflex akasanganiswa nemimwe mishonga yesora kunze kweDual Magnum (s-metolachlor) kana Outlook (dimethenamid-p) kazhinji inovandudzwa kana ichienzaniswa nekudzora neReflex inoiswa yega. Pasinei neReflex rate mumatangi ekusanganiswa kwemishonga, kutonga kwemasora ose matatu aripo mumuedzo akanga akafanana uye aibva ku95 kusvika ku100 muzana. Kudzokorora kutongwa gore rino, Hutchinson anoti, ichapa kujekeswa.
Hutchinson akataura kuti ari kuona zvimwe zvezviratidzo muyedzo iyi sezvaange achiona mundima dzekutengesa-shizha diki richipfakanyika uye kuoma-nemamwe marudzi anoita seanoshivirira kupfuura mamwe. Akataurawo kuti, sezvaitarisirwa, zuva rega rega kunenge kuchidziya uye kune zuva, zviratidzo zvinova zvishoma uye zvishoma uye kuti ruzivo rwake neongororo iyi uye nezvimwe zvakaitwa munguva yakapfuura, zvechokwadi zvakamubatsira kupindura mibvunzo yemurimi uye zvinomunetsa.
