Machena machena: Zviratidzo zvekutanga zve powdery mildew
Powdery chakuvhe, dota, guruva, guruva, dota, cendrada, sendrosa, sendreta, malura vella, blanqueta, nezvimwe. Zvichienderana nenzvimbo, inozivikanwa nezita, asi vese vanopindura izvi mushwa (Uncinula necator) iyo inovhara mashizha ane grey kana chena kupfeka yakafanana nedota. Sezvo chirwere ichi chichienderera mberi, mashizha anoita yero uye ooma.
Iyo inowanzoitika yenguva ine tembiricha dzakapfava uye hunyoro hwakakwira. Mavise, magaka, manwiwa uye zucchini zvinokanganiswa nazvo mukati primavera. Makabheji uye chard tambura nazvo kudonha. Saka ikozvino zvatatanga neyedu chiruva Autumn, chenjera ne powdery mildew nekukurumidza apo tembiricha inotanga kudonha uye hunyoro hukakwira.
La nzvimbo yeMediterranean ndiyo imwe yenzvimbo dzinowanzoitika kuhupfu. Humidity yakakwira, tembiricha yakadzika, mweya wakasviba, mwenje wakaderera mwenje, mweya wakasviba uye kunyangwe yakawandisa nitrogen inofarira kupararira kwayo. A yakanyanya kukwirira kwemiti mubindu redu remumaguta inoita kuti aeration iome uye inogona kuve chikonzero chekuwedzera kweiyi fungus.
Para kudzivirira chitarisiko chayo tichadzivirira madhaka uye sosi, tinofarira kufefetedza uye aeration pakati pezvirimwa zvakasiyana uye tinokwanisa kuisa mapiritsi propolis pamashizha (3 ml. per litre yemvura), iyo inoshandawo semushonga wekuuraya fungus nemabhakitiriya uye inowedzera dziviriro yemuti. Iyo gadziriro yemabhiza y garlic iwo zvakare akanyanya ekudzivirira.
Kana tangoona iyo zviratidzo zvekutanga yedenda (kuoneka kwemavara machena, sekunge riri guruva) zvakafanira kuti ubvise pakarepo mashizha ane hutachiona nekuvandudza aeration yebindu nekuchekerera kana kubvisa zvimwe zvirimwa kana paine kuwanda kukuru, sezvo iyi fungus inopararira nekukurumidza kana mamiriro acho akanaka. Kana iyo powdery mildew ikafambira mberi, kukura kunononoka, mashizha anozoita yero ofa.
Para kurwa powdery mildew tinogona kuzora marapira pamashizha:
- skimmed mukaka (hafu yetita yemukaka yemvura masere). Inoshanda kwazvo.
- hydrogen peroxide yakadzvanywa mumvura (75 ml ye5 l emvura).
- sarufa, kungave kune aqueous kupuruzira kana muupfu wakapihwa nemabhero (usambotumbuka)
Mamwe mashoko - Potted chard, Hari yemaruva, Gadzira fungicide yezvakatipoteredza kumba, Kugadzira chipembenene kudzinga pamba
Mhoroi, ndinobva kuArgentina, uye ndanga ndiine zvishoma chard zvirimwa mubindu rangu kwechinguva, uye ndakaona kuti dzakatanga kushanduka kuchena sekunge vakasasa madota kana hupfu pamashizha avo. Mazuva maviri apfuura mashizha pazasi akatanga kuita yero. Ini ndaida kuziva kana iri powdery mildew? Uye kana uchikwanisa kudya mashizha ayo achiri akasvibira asi akasvibiswa neiyo chena hupfu. Uye chii chandinofanira kuita kuti ndirape? Kana kana iwe uchizofanira kucheka kana kubvisa zvirimwa zvakananga? Ndinovimba mhinduro munguva pfupi.

Kubva pane zvaunotaura zvinoita kunge powdery mildew. Muzviitiko izvi zvinokurudzirwa kuchekerera zvikamu zvakakanganiswa kudzivirira zvimwe zvirimwa kubva mukutapukirwa, nekurapa negariki (50 gramu muuta imwe yemvura) kurwisa.
Thanks.
Ndatenda zvikuru nemhinduro yako !. Ikozvino ndazvicheka kune ese chard zvinomera uye ndichaona sezvavanokura kana zvikanyangarika asi sedziviriro ndichaita zvawakakurudzira, maita basa!.
Masikati akanaka. Ndine mibvunzo yakati wandei ine chekuita nehupfu hwakasviba. Ndinozvipfuudza pazasi
1.- Ndeipi mhedzisiro kune vanhu yekumedza chero muriwo / miriwo iyo yakatapukirwa neiyi fungus?
2.- Kuonekwa kwefungus kunogona kudzivirirwa sei?
3.- Iyo mishonga yavakapa, kangani inoda kushandiswa? Mukaka wakaomeswa unoshanda zvechokwadi here? Mubvunzo wangu ndewekuti kana iri kamwe pasvondo, mazuva ese, ...
Ndatenda zvikuru pamberi pezve idzi tsananguro dzamakapa.
Thanks.
Ndinokumbira mhinduro netsamba.
Mhoro vatengesi.
1.- Unogona kusagadzikana, manyoka, kurwadziwa nemudumbu.
2.- Iyo nzira inoshanda kwazvo yekudzivirira kuoneka kwayo ndeyekudzora njodzi nekutarisa humhutu hwevhu usati wadiridza, nekudzivirira kunyorovesa mashizha, maruva nemichero.
3.- Iyo mishonga inogona kushandiswa kamwe pasvondo. Panyaya yemukaka wakaomeswa, chokwadi ndechekuti ini handina kukwanisa kukuudza nekuti handina kuzviedza, asi sarufa ndinogona kukuudza kuti ine fungicide ine simba uye inoshanda.
Thanks.
