Chirwere ichi chinowanikwa mune dzimwe nyika iyo mbatata inowedzera massively. Pamwero, kurasikirwa kwezvirimwa kunogona kusvika kusvika makumi manomwe kubva muzana.

Mbatata inenge ichinetseka ichi chirwere chinokonzera fungal, iyo causative agent iyo inonzi pathogenic. Inobata tuber, stems, maruva, midzi midzi.

Zviratidzo zvekutanga zvechirwere zvinogona kuonekwa pane mashizha uye mashizha epamusoro. Mbatata inopera nguva yakaipa inokuvadza zvikuru, sezvo inokanganisa vaduku uye physiologically zvikamu zvinoshanda zvikuru zvemuti, vachideredza zvibereko zvavo.

Nekuderera kwebasa rakafanana pamashizha emudziro wezvibereko, nzira yekuumbwa uye kuwedzerwa kwezvibereko zvakawanda zvinokanganiswa, kunyanya muchikamu chekubata mbeu.

Somugumisiro, ruvara rune ruvara rwemavara nemaitiro anotungamirira tinge rinowanikwa pamashizha. Vanowedzera zvakajeka, vakakurumidza kuputira gwenzi rose, uye vozoenda kune dzimwe nzvimbo dzakapoteredza.

Mumamiriro ezvinhu akanaka, kunonoka kwemazambatara kunopararira zvakasimba zvokuti mumazuva masere kana gumi chete inogona kuvhara nzvimbo yose.

Panzvimbo dzakasvibiswa mumangwanani mangwanani kana mumvura yakanyorova, kupfeka kwakachena kunowanikwa pazasi kwemashizha. Uyu ndiwo mhirizhonga wezvimedu zvinomera. Mune mamiriro okunze akaoma, chikamu chepamusoro chinoputika chinosvava, chinoputsika. Mushure memvura, inokurumidza kuora, ichipararira kunenge isina simba yakasvibirira.

Nheyo yemiti inenge yakasvibiswa nepamusoro pematatata inoratidzwa nekuumbwa kwezvidimbu zvezvikwata zvefa mavara tsvina. Dzimwe nguva vanofukidza yose yepamusoro yemiti.

Pamatera aya, chirwere ichi chinoratidzika sechimiro, chakashungurudzika, nzvimbo dzakatsanangurwa zvakanaka dzinonyanya kuonekwa pamusana wemucheche. Mamwe mabhakitiriya ane fungi anopinda mukati memishonga yakakanganiswa, iyo inowedzera kusimba kwezvirimwa.

Mbatatari inopera blight inosangana chete nezvibereko zviri mukutanga kwekutsvaga. Pakutanga, nzvimbo inenge isingaoneki yakachena yakareba yakaonekwa, iyo inopararira zvishoma nezvishoma mumusanganiswa mutsvuku. Kuwedzera muhupamhi, kuchema kwekupedzisira kunotora zvishoma nezvishoma mbatata yose, iyo inoderedza uye inotanga kuora.

Ichi chirwere chinokonzera kupisa chinoparadza kwete chete mbatata zvirimwa, asiwo pamwe nemamatare anotora. Inofadza ndeyekuti zvirimwa zve aubergines uye zucchini hazvibatsiri zvachose, kunyangwe nevavakidzani vepedyo vane zvirwere zvine utachiona.

Mazuva ano, kurwisana nekunonoka kwemazamu mbatata ndiko kunyanya kushandiswa kwembeu yemhando dzakasimba. Mukuwedzera, kusarudzwa nokungwarira panguva yekugadzirisa kwemashoko okudyara kunokosha zvakanyanya pakudzikisa kusimbiswa kwechirwere ichi.

Mune dzimwe nyika, mbatatisi mbeu inobatwa nefungicides munguva yekuchengetedza. Izvi zvinoitwa kuti tisabvisa kuve kwekuora, kusanganisira phytophthora.

Sezvo zvinyorwa zvitsva zvehutachiona zvinenge nguva dzose zvichirwara zvirwere, nyanzvi dzinokurudzira kuparadza dumps yemapatatisi, yakasiyiwa mushure mekuvhara bulkhead yekukohwa.
