Iyo toll iyo inopisa yakaoma mamiriro ekunze yakatora paRed River Valley 2021 chirimwa chembatatisi hachizoonekwe kusvikira kukohwa kwatanga mumavhiki mashoma, asi zvatova pachena kuti zvakakanganisa goho uye mhando.
Gary Secor, North Dakota State University chirimwa pathologist:
"Tine zvinetswa zvakawanda zvemuviri."
Secor aive mumwe wevazhinji NDSU uye University of Minnesota vaongorori vakataura neChina, Nyamavhuvhu 26, kuNorthern Plains Potato Growers Association zuva reruwa pedyo neLarimore, North Dakota.
Zvichakadaro, kusanaya kwemvura kwakaderedza gohwo rembatatisi tsvuku dzakakurira musika mutsva. Varimi tarisiro, zvakadaro, kuti mvura dzichangoburwa dzichawedzera uremu kuchirimwa uye kuita kuti kuchera kuve nyore. Vanosvika mazana maviri varimi vakapinda gumbo rekutanga rekushanya kwemazamu zuva reHotverson Farms padhuze neLarimore kuti vanzwe vatsvagidzi vembatatisi vachipa ruzivo nezvechirimwa ichi.
Mushure mezviratidziro zvemangwanani, kushanya kwezuva remunda kwakatamira kunzvimbo yekutsvaira yekudiridzira yeNorth Plains Potato Growers Association padhuze neNkster, North Dakota, uye manheru, kuOberg Farms, padyo neHoople, North Dakota.
Red River Valley ndiyo inogadzira mbatatisi tsvuku muUnited States, uye North Dakota neMinnesota zvakasanganiswa inzvimbo yechitatu yakakura kurima mbatatisi munyika. Varimi vembatatisi kuNorth Plains vanokwidza 62% yematapiri ekugadzira fry, 10% yembeu, 12% yekucheka uye 16% pamusika mutsva, sekutaura kweNorth Plains Potato Growers Association.
Mamiriro eNorth Dakota mbatatisi, iyo inosanganisira kugadzira uye nyowani stock, muvhiki rakapera Svondo, Nyamavhuvhu 23, yaive 8% yakashata kwazvo, 14% yakashata uye 63% yakanaka, sekureva kweNational Agricultural Statistics-North Dakota. Iyo agency yakaratidza chete 13% yezvirimwa zvakanaka, uye 2% yakanakisa.
KuMinnesota, uko makumi maviri kubva muzana ematatata akange akohwewa kubva munaAugust 20, 23% yechirimwa yakanzi yakanaka kusvika kune yakanakisa, National Agricultural Statistic Service-Minnesota akadaro. Kunze kweRed River Valley, matatata ehurumende anorimwa muElk River uye Park Rapids nzvimbo dzeMinnesota uye padhuze neAlbert Lea.
Kumusoro kwekupisa uye kuoma kwemamiriro panguva yekukura kwegore ra2021 ndeyekuti chirimwa chembatatisi cheRed River Valley chaive chisina chirwere.
Semuenzaniso, kunonoka kusvibiswa, chirwere chembatatari chinokuvadza mashizha uye tubers, hachina kuoneka mune chirimwa gore rino. Munguva yemvura inonaya, varimi vanofanirwa kungwarira nezvekutarisa minda yavo yembatatisi uye voisa mushonga wemushonga kana vakaona blight yakanonoka, chirwere chinogona kukonzera kurasikirwa kukuru kwegoho.
Kunyangwe imwe yekuchamhembe kwakadziva kumadokero kweNorth Dakota uye kuchamhembe kwakadziva kumadokero kweMinnesota minda yemazamu nguva pfupi yadarika yakagamuchira mvura, kunonoka kusvibisa hakuzoite nharo nekuti hapana inoculant yekufemera kutenderera. Nekudaro, kusagadzikana kwepanyama inyaya inogona kuve yemhando nyaya.
Kupisa kunopisa panguva yekukura kwakakonzera kusagadzikana, uko kunosanganisira kupisa kwemukati necrosis uye moyo wakadzika.
Matambudziko maviri epanyama haakanganise kuchengetedzeka kwembatatisi, asi vatengi havafarire kudya mbatatisi ine mavara akasvibira mukati membatatisi, zvinova ndizvo zvinoitika mukati mekupisa necrosis, kana mbatatisi dzine mavara matema. , chinova chiratidzo chehwindi moyo.
Kuonekwa kusingakwezve kwemukati membatatisi kunogona kukonzera kudzikiswa kwekudzokorora kutengesa. Mhedzisiro yezvibereko haina chokwadi. Kukohwa kwembatatisi kunotanga mumavhiki maviri.
Parizvino, chirimwa cheHoverson Farms, icho chakatakura chikamu cheNorthern Plains Potato Growers Association zuva reChina, chinotaridzika zvakanaka, asi tubers iri pasi pemiti inoda kuwedzera saizi, akadaro Carl Hoverson, muridzi wepurazi nevanakomana vake, Mike na Casey.
Pasi pemadiridziro, Hoverson Mapurazi anokura angangoita zviuru mazana mashanu nemazana mana ematatata ekugadzirisa, kutsemura uye tafura yemusika wemusika. Hoverson Mapurazi achatanga kukohwa mbatatisi musi waGunyana 5,400, mamiriro ekunze achibvumidza, uye vanotarisira kuti pavhareji goho remakumi masere nemazana mashanu emazana emapagi paeka, akadaro Carl Hoverson.
Kukohwewa kwembatata tsvuku, kwakasimirwa musika mutsva, kuchatanga pakati paGunyana, akadaro Donavon Johnson, Northern Plains Potato Growers Association purezidhendi. Johnson anofungidzira kuti goho rembatatisi dzvuku, mazhinji acho anorimwa pasina kudiridza, achave akaenzana. Zvibereko zvakanaka zvembatatisi zvinobva pamakumi matatu nemaviri kusvika mazana matatu nemakumi mashanu nemashanu ezvirema, akadaro.
