Phytophthora inorwisa iyo inogona kuderedza zvakanyanya kukohwa kwemiriwo uye kunyange kuparadza mbeu yose yembatata. Zviratidzo zve phytophthors pane mbatata zvinotaridzirwa kune ziso rakashama: kutanga, mavara ane maronda anopindira mashizha mashoma emuti, zvishoma nezvishoma anotendeukira kumashizha ekumusoro, mashizha uye tuber. Pasi pematata inotungamira-grey, inonyorera uye inononoka kune iyo inobata, uye nyama inowana hutu hunotyisa. Chimwe chinokonzera kukura kwechirwere chacho, mvura yakasununguka. Kurwisana nemapatato phytophthora kunosanganisira nhamba yezviyero.
Nzira dzokurwisa phytophthora pane mbatata
Kuchengeta varwere tubers
Sezvo chikonzero chikuru chekutapukirwa chiri kurwara tubers, kuchengetedza mbatatisi kubva ku phytophthora, zvinodikamwa kusarudza zvakanyatsonaka zvinhu zvakasanganiswa nefungus. Zvakakosha kuti urege kungoisa zvimedu zvakashata munzvimbo yekamba kana kuti uzvikanda pamusoro pefambo, zvinonyatsokosha kuti ucheke midzi inotsika pasi kana kupisa, zvisinei kuti spores inomira kusvika kure makiromita mashanu.
Kururamisa kugoverwa kwemhando dzakasiyana-siyana dzepatate nemiriwo
Hazvina kunaka kudyara marudzi ekupedzisira-kubereka pamwe chete nemhando yekutanga uye yakabereka, iyo inokonzerwa nekupera kwemazuva ekutanga. Kana zvichibvira, zviri nani kudyara mbatatisi gore negore kunzvimbo itsva. Hazvigoneki kudyara utamatisi munharaunda, iyo inoratidzirwawo nekunonoka .
Kemikari kugadzira mbatata
Kuchengeta mbatatisi kubva pakupera kwemazuva ano, makemikari ekugadzirira anoshandiswa. Kugadzirisa mubvunzo, chii chaungaita mbatatisi kubva ku phytophthors, kunyanya kufunga nezvekushandiswa kwezvirimwa tsika. Pakutanga kudyara, mbatatisi inobatwa kaviri mukukwira-muchitsiko chepamusoro, kuchengetedza nguva yevhiki mashanu. Panguva ino fungicidal zvakagadzirwa zvinoshandiswa kubva ku phytophthors pane mbatata: Arcedil (50 g ne 10 l wemvura), Ridomil MC (25 g pa 10 l) uye Oxcich (20 g pa 10 l). Mushure memaruva, kurapwa kunoitwa nekubatanidza maitiro ekugadzirira: Ditamin M-45 (20 g pa 10 L yemvura), mhangura yekorodi (40 g pa 10 L), Kuproksat (25 g pa 10 l). Nhamba yezvirapa ndeiyi 3-4 pamwaka, nguva inenge iripo pakati pemishonga inenge 1 vhiki.
Kukura kwemazamu anotapira kusvika kunopera
Kusarudzwa kwemarudzi embatata asingagadziri kusvika pakupera kwechiedza ndiyo nzira yakanakisisa uye inobudirira. Munzvimbo umo chirwere ichi chemazambatadzi chinowanzo, mbeu dzinofanira kudyarwa, dzisinganyanyi kuonekwa nekuratidzwa kwayo: Nevsky, Spring, Arina, Golubichna, September, Mavka, Ogonek nevamwe.
Kuteerera mitemo yekukohwa mazamu
Kuchengetedza chirwere chakadai chisingafadzi chemazambatori sechiedza chekupedzisira, zvinokosha kuti ugadzirire zvakakwana kudyara kwemasikati kwegore rinouya. Nokuti izvi, mushure mekukohwa, iyo tubers inofanira kuomeswa. Kana mamiriro okunze ari akaoma, ipapo mbatata yakaoma zvakananga panzvimbo iyi, kana kunaya - kuoma kunowanikwa pasi pedenga. Mushure mokunge mbeu dzacho dzioma, ita chikamu chechipiri chemazambatata, uye chete ipapo chibage chakaiswa kwenguva refu yekuchengetedza . Bvisa kunyange iyo tubers iyo inoshamisa, nokuti pashure pemwedzi 1.5 mushure mekudyara, fungus icharamba ichiratidzira, uye hutano huchawana hutachiona
Kuchengetedzwa kwembeu usati wasima
Varimi vemikumbi vakanzwa kuti nekuwedzera kukurira kwemazambatata, kudyara tubers kunobatwa nemishonga. Asi havasi vose vanoziva kuti vangaparadzira mbeu mbatatisi kubva paprophthors. Agrotechnics inorayirwa kuti iite kurapwa kwemazuva maviri usati wasima Agatom-25K (3 magamu pa 250 ml wemvura) kana Immunocytophyte (0.4 g pamus 150 ml). Iyi yakawanda yekugadzirisa inokwana kubata makirogiramu makumi maviri ematata.
Tinotenda nekuda kwegadziriro yekudzivirira iwe unogona kuunganidza yakawanda kukohwa kwekunakidza yemidziyo tsika!
