Mukuwedzera kune zvese zvinowanzozivikanwa zvehutachi tsika - iyo inovengwa Colorado mbatata beetle , pane zvirwere zvakawanda zvinotungamirira pakuderera kwezvibereko. Zvimwe zvirwere zvinotungamirira kushandura mashizha. Ngatitaurei nezvechiitiko chisingafadzi uye nzira dzokurwisana nayo munyaya yacho.
Mashizha etazhu inoshandiswa - zvikonzero
Boka rokutanga rezvikonzero ndizvo zvirwere zvehutachiona. Izvi zvinosanganisira:
- Mifananidzo yakashata. Kukundwa kunosangana nelagi mukukura, nhamba shomanana yematombo, wrinkles uye kuputika kwemakona emashizha. Izvozvo ndezvekuguma kwekukura kunononoka kwemitsipa.
- Mosaic stripe. Chirwere chacho chinoratidzika panguva yekusviba kwemazamu. Pakutanga, nzvimbo dzakaoma dzemavara dzinoonekwa - necrosis yemashizha kubva kurutivi rwezasi, ane zvipembenene zvakanyanya mashizha anoputika kufa, akaturika pamatemu. Chaizvoizvo, mashizha ari pasi akabatwa, mupfuti unoramba uine ruvara. Zviratidzo izvi zvinowedzera munguva yekupisa kukuru.
Nzira yekugadzirisa nayo kana mashizha emukirasi wepatato nemhaka yehutachiona hwekuvhara: kuchengetedzwa kwemazambatari kubva kune zvirwere zvehutachiona ndiko kubviswa panguva yakakodzera yezvirimwa zvine utachiona pamwe chete nemashizha ayo, kutora uswa, kukohwa panguva yakakodzera. Sembeu, chete ndiyo yakanakisisa tubers inotengeswa mune zvekugadzirwa kwepamusoro inofanira kusarudzwa.
Chikamu chechipiri chezvikonzero zvekunamatira mashizha eti mbatata zvirwere zvehuturu:
- Phytophthorosis - haibatsiri mashizha chete, asiwo maitiro uye mbatatari tubers. Chokutanga, mavara madhena uye madema anoonekwa pamashizha, kana simiti isingatariswi, iyo tubers pamusoro pekuchekwa ichava yemavara uye yakaoma. Nzira dzokurwa nadzo ndeyokudzivirira, kuiswa kwezvinhu zvakakosha zvinotevera muvhu, munguva yekukura unoda kushandura mabwenzi ane mazano akafungidzirwa.
- Parsh - inotungamirira pakukanganiswa kwemashizha, midzi yebatei inosvibisa uye zvishoma nezvishoma kufa. Zvisina kusimba zvinomera zvinowanzosangana nechirwere ichi. Mushure mekumera mbeu, chirwere chacho hachina kuchinja mbeu. Saka zvakanakisisa kudyara kakatooma mbatatisi uye kuve nechokwadi kuti hapana mhepo yakasvibira pamumipata. Usati wasima, iyo tubers inobatwa ne 1.5% solution ye boric acid.
Izvi zvikonzero zvinotevera nei mbatatisi yakanyungudutswa mashizha anosanganiswa nehosha dzebhakitiriya. Icho chikuru ndechegumbo jena. Iyo inowedzera panguva yekuchengetedzwa kwemataipi, uyewo munguva yekukura kwemuti. Kutanga, maapical mashizha anosiya mazamu muzamu, ipapo nheyo yehutende inotendeuka uye inoora. Zvimwe chete zvinodzivirira zvichabatsira pano: kutanga kunomera kwe tubers, kupinda kwavo mune imwe sarudzo ye microelements-boron, copper sulfate, manganese uye zinc.
Dzimwe nguva chikonzero chekuti mbatatende inosvibira uye mashizha anoputika isanaya uye kupisa kwakanyanya, chii chaunofanira kuita munyaya iyi: kunwisa nekuchera misoro, unogona kuputira mabhedha kuchengetedza unyoro muvhu refu.
