Kana iwe ukawana chivara chakachena-chena pamashizha emichero kana mabhola machena, muti wacho unoshushwa ne powdery mildew. Kuvhara kwechiedza zvishoma nezvishoma kunotanga kuvhara uye pamagumo kunowana tambo tsvuku. Ichi hachisi chinhu chinopfuura mycelium inorarama pamutengo wegwenzi. Bhurau bhora ndeye fungus spores. Ngozi yechirwere ichi ndeyotevera: chimiro chinopera zvachose chitarisiko chekushongedza, uye nzvimbo dzakakanganiswa zvishoma nezvishoma zvinotendeuka dema ndokufa. Kana inflorescences inokanganiswa, haigoni kuumba mavari. Mukuwedzera, chirwere ichi chinonyanya kuderedza kupikisa munguva yechando.
Sezvo mutemo, kutanga kwehutachiona kunoitika pakutanga kwezhizha. Munguva iyi, spores inosunungurwa kubva muzvibereko zvemufudzi we fungus. Mune nguva yakaoma panguva yekupisa, kana pane kuchinja kwakakomba kwekushisa nekunyorova, mamiriro ezvinhu akanaka ekugadzirwa kwepodaviry mildew kuonekwa. Izvi zvinoitika kuti kuonekwa kwechirwere kwakashandisa kushandiswa kwakanyanya kwe nitrogen fertilizer. Kana kudzvara kwakasimba kunogadzirisa kwaitwa, simiti haigoni kurwisa.
Powdery mildew chirwere chefungal. Inoparidzirwa nemhepo kana kuputika kwemvura munguva yekudiridza.
Ungabvisa sei powdery mildew?
Kurwisana nemukaka kunotanga nekudzivirira. Muzhizha, kuparisa kunofanira kuitwa kanenge kanomwe. Kana zvichibvira, usashandise nitrogen fertilizer munguva yebhinzi, izvo zvinowedzera kuipa kwechirwere. Wedzera kumira kwe potassium uye phosphate fertilizer.
Kurwisana ne powdery mildew kunofanira kutanga panguva, zvisinei zvinopisa denda rose. Iyo fungus inofarira kuchando pamiti yakasara, saka zvakakosha kubvisa nguva nenguva uye kupisa kana kuidzikisa muvhu.
Pasi pamakwenzi eGooseberries uye currants inofanira kubviswa pamigumo yakasvibiswa yemashizha mukati megore. Iva nechokwadi chekudyisa mabhiza ne "yakarurama" fertilizer. Mushure mokunge mushure mokunge maruva, zvakafanira kurapa simiti ne calcined soda. Rimwechete mu 2-3 makore rinobvumirwa kushandisa kupedza kupera mapiritsi ne ferrous sulfate solution.
Muchekawa, machupusi uye mbatya, chirwere chinokanganisa chikamu chemuviri. Muchiitiko ichi, mashizha anotanga kuvhara uye kuparara. Iwe unokwanisa kusvibisa mbeu ne colloidal sulfure kamwe pavhiki. Heano mapoka mapoka:
- kusanganidza 50 g ye sulfure ne 5 g yemhangura sulphate uye inonaya mu 10 malita emvura;
- kusanganidza 100 g yewasi yekushamba uye uwedzere kune 5 g ye vitriol, yose inonatswa mu 10 malita emvura;
- iwe unogona kugadzirira mhinduro ye Mullein muchiyero che1:10, kusimbisa kwemaawa mana.
Kunewo dzimwe nzira dzokuti munhu angabvisa sei mesh powdyy. Heano mapoka mapoka:
- muna 1 litre yemvura, sungai 4 g ye soda ash uye 4 gramu yewaini yakashamba. Mhinduro yacho inoshandiswa nemiti zvakapetwa kaviri vhiki;
- in 1 litre yemvura inwaya inopedza hafu yegirazi yemhangura. Kumanikidza kwemazuva maviri. Dissolve solution uye uwedzere kwairi 4 g ye sese yakanyungudutswa. Dzokorora iyo michero kaviri pane imwe nguva pavhiki.
Powdery mildew pamaruva
Kune murairi wemaruva, dambudziko iri harina kunyanya kukurumidza, nokuti chirwere ichi chinowanzokonzera mukati maro maruva.
Asi zvose zvakafanana, zviyero zvekurwisa powdery mildew pamaruva aripo. Kuti uchengetedze muti, iwe unofanirwa kupindura nokukurumidza sezvinobvira. Iko kune nzira dzakasarudzika dze powdery mildew, iyo inogona kutengwa muzvitoro zvevaflorist. Mushonga we "Topaz" unoshandiswa maererano nemirairo yemiti yose, kunyange yakagwinya. Inowanzokwanira kugadzira maruva kamwechete.
