Powdery mildew - zviratidzo, kudzivirira, kurapwa

Zvirwere zvezvirimwa zvakawanda mumunda. Inonzi fungus. Icho chinoratidzika se powdery, white coating. Mashizha anokonzerwa nefungus iri uye anowa. Chimiro chinosvava uye nokukurumidza chinofa zvachose. Mildew inowanikwa mumunda wega wega, "kubudirira" mukati memwedzi mushure mokubuda. Zvinokonzera kuonekwa kwefungus pamashizha ndezvekuti: yakasimwa zvakare, ivhu rakashata, kudiridza kunononoka, kuchinja kwakakomba mukati mekushisa kwezuva maererano neusiku (kupisa-kupisa).

Powdery mildew ndeyechokwadi. Chiratidzo chikuru ndechekuonekwa kweiyo yakanyorwa pamusoro apa kwete pamashizha chete, asiwo pamashizha uye kunyange maruva. Chirwere ichi chinokurumidza kusima chikamu. Mashizha akavhara, asi usagumburwa kwenguva yakareba. Chikonzero chacho chiri mumiti yakasvibira uye kudiridza zvishoma. Chienzaniso ndeye powdery mildew pa gooseberries: mashizha akaomeswa anomira kukura, akaoma, kuputsa; Zvitsva, zvisati zvakura, zvinoderedzwa. Somugumisiro - kusavapo kwekukohwa nekufa kwechirimwa mugore kana maviri.

Powdery mildew ishema. Chiratidzo chikuru - kuoneka kwe "faded" kana kuti tsvuku-mavara machena pamusoro pejira, pasi apa inoratidza grey mold. Chimiro chiri kuderera, kuipa. Kuonekwa kwezvibereko kunokwanisika, asi hutano hwavo hwakadzika, hwakasiyana-siyana. Muenzaniso ndeye powdery mildew pamakucheka. Chikonzero chikuru chekuonekwa kwemafungi akadaro pamiti yacho inogara muusiku husiku uye masikati makuru ekupisa.

Kurapa kwezvirimwa zvakakanganisika kunogoneka, asi zviri nani kufunga nezvekudzivirira. Kuchenesa kubwinya kwekudyara, sarudza nzvimbo dzakaputirwa nemhepo, kupa mvura nguva dzose, kuwana michero yemiti isingagamuchiri. Kubviswa kwehutachiona hwehutachiwana uye mashizha anopiswa. Iyo ivhu iri mumakona uye kumativi ose emasango inogadzirwa, mushure mokunge kuwedzera mashoma nemafuta (potassium uye phosphorus-nitrogen) inoitwa.

Chibereko chakanaka ndiko kuputira kwezvirimwa zvine utera hwakakosha we soda ash (0.5%) pamwe nekuwedzerwa kwemajasitiri ejasisi. Fukidza kazhinji kano: musati watumbuka, pakarepo mushure mayo, vasati vakohwa (mazuva gumi) uye zvakare mumavhiki maviri.

Kana powdery mildew yave yatozviratidza, ita zvinomera zvinoshandiswa (kubvisa nzvimbo dzakapararira dzakapararira (mashizha uye kunyange matavi), fungicide.) Kemikari inoreva, saka kubvumirana nehuwandu uye kushandiswa kwezvidziviriro (magirafu, mask) zvinotenderwa.

Chinhu chinokanganisa kunoshandisa kushandiswa kwemishonga "Topaz". Inoda kubatwa kaviri, kunyange zvazvo imwe chete (mushure mokupenya)

Imwe mishonga inonzi inotsiva muganhu weBordeaux "HOM". Masango anotsvedzwa asati asvava, maererano nemirairo.

Muvanhu, "mishonga yepamusha" yakapararira: bhari ye sopu yakanyoroveswa uye 20 g ye vitriol inopedzwa mubhodhoro remvura (10 litita). Chigadziriswa chinokonzera matate-bhuruu inoshandiswa nemiti mushure mekunge ichitumbuka.

Inogona kurapwa nemhinduro ye sopu yemumba (50 g) uye soda (50 g), yakagadzirwa mubhakiti remvura. Mvura inodururwa kubva mumvura inodiridza neyemuchero wakanaka pamberi pemashizha asati apera (pamagwenzi - matatu malita e solution) uye mushure mokupenya.

Imwe, kwetewo nzira yakaoma, inoda 3 kg yemhangura uye bhakiti remvura inopisa (iyo madota inodururwa nemvura inopisa). Kuvharirwa kubva pamadota kunoshandiswa pamiti isati yatumbuka, uye pashure payo (imwe nguva yemazuva anenge gumi).

Ichokwadi kuti mapoka ose haafaniri kushandiswa panguva imwe chete, ichava kutsvaga kutsvaga, izvo zvinogona kungowedzera mamiriro acho ezvinhu. Zviri nani kusarudza imwe, nzira yakakodzera. Kazhinji, zvirwere zviviri zvegore zvakakwana. Kunyanya kana pakusima (kana kudyara) unosarudza marudzi asingadziviriri ku powdery mildew.

Uye imwe pfungwa inokosha inokosha: itsva, itsva inowanikwa, inofanira kunge yakasvibiswa. Nzira yakanaka yechinangwa ichi ichava 1% yendarira sulfate. Mbeu dzinochengetwa mune iri sarudzo kwemaminitsi mashanu, yakashambidzwa nemvura ndokuzodyarwa.
