Zviri mukati
Yakapupurirwa, organic uye yakasikwa mhinduro dzekubvisa mbatatisi scab kumba uye mubindu.
Chirwere chetuber chinowanikwa pese panorimwa mbatatisi. Zviratidzo zvembatatisi scab zvinosanganisira rima rakasvibira, mavara ane pithy anogona kusimudzwa uye "warty." Izvi zvipembenene zvinogona kukanganisa chikamu chiduku che tuber pamusoro kana kuvhara zvachose. Dzimwe nguva mbabvu zvikamu zvakaputsika concentric zvindori.
Unogona here kudya mbatatisi ine crust?Ndinobheja! Miti yakakanganiswa, kunyange zvazvo isingatarisirwi, inogona kudyiwa. Ingo cheka kubva kune corky mavara kubva paganda uye / kana nyama uye kubika semazuva ese. |
Mbatatisi scab inokonzerwa nemabhakitiriya akafanana ne microorganisms. Streptomyces scabies, overwintering muvhu uye mashizha akawa. Mhuka iyi inogona kurarama nekusingaperi muvhu rine alkaline zvishoma, asi iri shoma muivhu rine acid yakawanda. Inotapurirwa kuzvirimwa kuburikidza nemachubhu embeu ane utachiona, mhepo nemvura. Hupenyu hunowaridzwawo mundove itsva nekuti hunogona kurarama nekupfuura nemudumbu remhuka. (Dzidza nzira yekurima mbatatisi pano.)
S. scabies inopinda kuburikidza ne pores (lentils) mumadzinde, kuburikidza nemaronda uye zvakananga kuburikidza neganda revechidiki tubers. Mukuwedzera kune mbatatisi, zvimwe zvirimwa zvinotapukirwa: beet, radishes, turnips, karoti, rutabaga uye parsnips. Izvi zvinofanirwa kuverengerwa pakugadzira chirongwa chekutenderera kwezvirimwa.
Cherechedza: S. scabies inogona kuramba iri muvhu kwemakore akawanda mukushayikwa kwembatatisi.
Лечение
Ese anotevera matanho ekudzora aratidza kushanda kurwisa mbatatisi scab. Zvisinei, kazhinji kacho kusanganiswa kwenzira idzi kunodiwa.
- Dyarai mbatatisi dzakasimbiswa, dzisina mhodzi uye mhando dzinoshingirira pazvinogoneka. Tinokurudzira kushandisa mhando dzine ganda dzvuku-ruvara sezvo dzichinyanya kushingirira kuchirwere.
- Tenderedza midzi mbesa nekudyara munzvimbo dzakasiyana kuti zvirwere zvipere.
- Mbatata scab inonyanya kuwanikwa muvhu rakaoma, rine alkaline. Deredza ivhu pH nekuwedzera elemental sulfur. Chirwere ichi chinodzorwa kana kudzvanyirirwa zvakanyanya paivhu pH mazinga e5.2 kana pasi. Yakareruka uye inokwanisika yekuongorora ivhu kits inowanikwa kuti igare ichiongororwa pH.
- Kurapa mbesa dzinovhara—masitadhi, canola, nealfafa—usati wadyara mbatatisi kuchabatsira kuderedza utachiona.
- Vamwe varimi vanotaura kubudirira kushandisa gypsum yezvekurima vasati vadyara pamwero we25 pounds pa2,000 square feet. Izvi zvichawedzera calcium yevhu uye kubatsira kuvaka yakasimba sero madziro mumiti. (Cherechedza: S. scabies zvinokanganisa kusimukira kwemadziro emasero, izvo zvinotungamira mukukuvadzwa.)
- Kudiridza kwakaringana kutanga kwetuber kunokwanisa kukanganisa kubatwa nescab, asi unozofanirwa kuchengetedza ivhu rakanyorova kwemavhiki 2-6. Iyi nzira inoshanda nekuti hunyoro hwevhu hwepamusoro hunokurudzira kukura kwebhakitiriya, iyo inogona kubvisa S. scabies pamusoro pembatatisi.
- Do NOT pamusoro pemvura.
Zano: Kana muchinge muchidyara muvhu musati madyarwa machubhu kana kuti munzvimbo inozivikanwa kuti hamuna chikwambo, gadzirai mhodzi yembatatisi nemushonga weSulfur fungicide kuderedza kupararira kwescab.
