Umama we-Mealy ungenye yezifo ezivame kakhulu futhi ezingavamile ukuthi inani elikhulu lezitshalo lihlushwa. Kubalulekile ukulwa nalokhu, ngoba umphumela wesifo esingahoxiswa ukufa kwesitshalo. Okungajabulisi lapho lesi sifo sibhubhisa ubuhle bezitshalo zokuhlobisa.
Kulesi sihloko sifuna ukwabelana ngezincomo zendlela yokuvimbela isikhutha se-powdery ku-roses nokuthi kufanele senzeni uma sithinta izimbali.
Uyazi? Isikhathi sokuqala lesi sifo, njenge-powdery mildew, sabhalwa eYurophu ngo-1907. Kwangeniswa eMelika.
Iyini isikhumba se-powdery esiyingozi?
Abalimi be-powder, abalimi nabalimi bezimbali ngokuvamile bahlanganiswa ne-powdery isikhutha, njengoba kuthinta izingadi, okusanhlamvu, izithelo nezithelo kanye nezitshalo zokuhlobisa.
Lesi sifo sesibungulu sibangelwa isikhunta esiningi se-pathogenic. Uma sikhuluma nge-roses, bahlala kumakhowa okuthiwa "Sphaerotheca pannosaLew." Var. "Rosae Voron". Ngenxa yokuhlala kwawo emaqabunga, iziqu kanye neziqu zezimbali, lesi sitshalo silahlekelwa ukubukeka kwayo, siyeka ukukhula; amaqabunga akhe aphelile, engaveli; amaqabunga aphendukile asundu, aphendule amnyama futhi asomile. Ngenxa yalokho, ukufa kwembali kungabonwa. Ngisho nasesikhathini sokuqala sesi sifo kunciphisa kakhulu ukuzivikela kwezitshalo, futhi abakwazi ukubekezelela izimo zangaphandle ezimbi, ubusika obusika.
Kubalulekile! Izinhlobo ezimbili zama-roses zitholakala kakhulu e-powdery isikhutha: i-hybrid tea kanye ne-remontant.
Izimpawu zokunqotshwa
Izimpawu zesikhumba se-powdery ziyizinto ezibonakalayo: azidibanisi lesi sifo nanoma yikuphi okunye. Ngokunqotshwa kwezitho zezitshalo kuhlanganisa i-mealy embubheni-emhlophe i-plaque ebomvu-i-mycelium. Kubonakala sengathi kubukeka sengathi ufulawa luthululelwa kuma-sheet. Ngemuva kokuthi izinhlamvu zivuthwe, amaconsi angabonwa emgqonyeni - kusuka lapha ukuthi igama lesi sifo livela. Kamuva, ekupheleni kwehlobo, ukuqhakaza kuyaba mnyama, futhi phezu kwamaqabunga, ama-stalks, ama-spores amancane ama-brown amnyama.
Njengomthetho ukutheleleka kwenzeka ngenyanga yokuqala yehlobo - ngalesi sikhathi lapho kukhishwa khona ama-spores we-fungus, ayesebenza ngobuningi emzimbeni wesithelo. Iqala ngamaqabunga aphansi, kancane kancane athola yonke imbali.
Izici ezithandekayo zokusakazeka kwesifo yilukushisa, umswakama ophezulu, izinguquko ngokuzumayo ekushiseni emini nasebusuku. Ngokuvamile, amazinga okushisa aphuma ku-22 ° C nangaphezulu anele futhi umswakama womoya ungama-60-90%. 
Kunezizathu eziningana zokusabalala kwesifo ku-roses:
- ukutshala izithombo ezithathelwanayo;
- i-agrotechnology engalungile;
- ukufika kokuqina;
- umquba we-nitrogen owedlule;
- Ukuntuleka kokudla okunomsoco, ikakhulukazi i-phosphorus ne-potassium;
- ukungabi namasu okuvimbela;
- ukutholakala kokhula e-rosearium;
- ukuphefumula kwemoya empofu.
Ama-fertilizer amaminerali, naphezu kokusebenzisa kwawo kalula, awafisi kakhulu emapulazini amaningi, ngakho-ke abantu bavame ukuthakazelisa indlela yokutshala izitshalo ngomquba owenziwe ngamakhemikhali, izimvu, ingulube, inkomo, ihhashi, udoti, umquba wenkukhu, amalahle, inambuzane, imvubelo.
Izinyathelo zokuvimbela
Yiqiniso, njenganoma yisiphi isifo, kungcono ukuyivumela kunokubhekana nemiphumela yayo. Ngakho-ke, izinyathelo zokuzivikela zithatha indawo yokuqala ekutshalweni kwama-roses. 
Lezi zihlanganisa:
- ukuhlola njalo izitshalo;
- ukuhambisana nezimo ezinconywayo zokutshala (ukugeleza kwenhlabathi, ibanga elilingene phakathi kwamahlathi, ukukhetha isayithi ngokukhanyisa okulungile, ukufika endaweni evulekile, evikelekile emoyeni);
- ukususwa okwesikhashana kokhula;
- Imikhuba efanele yezolimo, kuhlanganise nokuchelela njalo nokuhambisana nemithetho yokwethulwa kwezakhi - ungadluli nge-nitrogen futhi uvimbele ukungabi khona kwe-phosphorus ne-potassium, ukhetho lokunikeza izithako eziphilayo;
- ukupompela nge-prophylactic ngamalungiselelo akhethekile okuvikela;
- ukucubungula ngokuzenzakalelayo kwezitshalo ze-rose kanye nokuhlanzwa kwamahlamvu asomile nokumba ngokujulile izihlahla zomuthi;
- Okukhethwa kokutshala izinhlobo eziphikisana nezifo.
Uyazi? Abazalisi banamuhla baletha izinhlobo eziningana zama roses eziphikisana kakhulu ne-powdery isikhutha. Phakathi kwazo kukhona amaqembu engadini ama-scrubs, ukuhluma, isembozo somhlabathi nokukhuphuka.
Ngokusho balimi abanolwazi, izinhlobo ezinhlanu eziphikisana kakhulu zihlanganisa:- "Leonardo da Vinci".
- "Amabheyili omshado".
- Usuku olusha.
- "UWilliam Shakespeare 2000".
- "Rosters Yuterson".
0.25% i-Benomil, 0.4% i-Zineb, 0.1% i-Fundazol nayo isetshenziswa. Njengomthetho, ukwelashwa kwenziwa entwasahlobo ngaphambi kokutshala nezimbali ekwindla ngemuva kokushiya amahlamvu, isikhathi esiphakathi kokupuniza singukuthi izinsuku ezingu-10-14.
Izimpande-zokugqoka nazo ziyindlela zokuvimbela isikhutha se-powdery, okufanele senziwe ngaphambi kokuqubuka usebenzisa ingxube ye-superphosphate (0.3%) ne-nitrate ye-potassium (0.3%).
Amakhambi omphakathi
Ekuqaleni kwezimpawu ze-powdery isikhutha ku-roses, kufanele uqale ukwelashwa ngamakhambi abantu. Nazi ezinye izindlela zokupheka eziphumelelayo. 
Iresiphi 1. I-Whey (1 l), i-iodine (amaconsi ayishumi) axutshwe emanzini (10 l). Sebenzisa ukupuniza amahlamvu kanye neziqu kabili nge-interval of days 7-10.
Iresiphi 2. I-soda (40-50 g), insipho (40 g) exutshwe ngamalitha angu-10 amanzi. Tshala kabili ngesonto.
I-Recipe 3. Umquba omusha (ingxenye eyodwa yesithathu ibhakede) uthele amanzi (10 l). Ukusekela izinsuku ezintathu, ukuvuselela zonke izinsuku. Ukucindezeleka ngokusebenzisa i-cheesecloth. Phuza amanzi 1 kuya ku-10.
Iresiphi 4. Ukhula oluvuthiwe wegadi (isigamu ibhakede) uthele ibhakede lamanzi ashisayo. Faka futhi uvikele izinsuku ezimbili. Ngaphambi kokusetshenziswa, ubunzima. Ama-Dandelions, i-celandine, i-coltsfoot, i-planta kanye namanye amakhambi azokwenza.
Iresiphi 5. Ugarlic oqoshiwe (80 g) ufake ama-10 amalitha amanzi, ubilise. Kulula isixazululo, ukucindezeleka nokusebenzisa ukupuniza.
Izincomo ezijwayelekile mayelana nokwelashwa kwamakhambi abantu:
- Ukuphalaza kumele kwenziwe ebusuku ukugwema ukushisa emaqabunga.
- Ngaphambi kokwelashwa ngalunye isisombululo esisha silungisiwe. Izimali ezinjalo azihambisani nokugcinwa.
- Ukuphalaza kwenziwa okungenani izikhathi ezimbili, kuze kube khona ukunyamalala kwempawu zomonakalo.
- Ngaphambi kokucubungula, kubalulekile ukususa nokubhubhisa amapheshana agciwane kanye namafihlekile ngokushisa.
Kubalulekile! Naphezu kokuthi izikhambi zabantu azivame ukusebenzisa izinto eziyingozi empilweni yabantu, noma kunjalo, amehlo, impumulo nomlomo ngesikhathi sokwelapha kufanele ivikelwe ukuze izixazululo zingafinyeleli embranini ye-mucous futhi zingabangeli ukusabela kokugula.
Ukuhlaselwa kwe-Chemical
Uma izikhambi zabantu zingabi namandla okulwa ne-powdery isikhutha kuma roses, kubalulekile ukuqhubekela phambili ezinyathelo zokulawula okunamandla - ukupaka nge-fungicides: izidakamizwa ezenzelwe ukwelapha izifo zefungal.
Namuhla, ukukhethwa okukhulu kwe-bio-fungicides nama-fungicide e-systemic kudayiswa.
Phakathi kwamafungicide e-systemic avame ukusetshenziselwa ukuthi: "Skor", "Fundazol", "Maxim", "Topaz", "Baktofit", "Fundazim", "Kvadris".
Ekufuneni izimali, kunokwelapha ama-roses e-powdery isikhutha, abalimi basebenzisa indawo yezinhlobo ze-bio-fungicides, ezifaka:
- "Fitosporin-M".
- "Alirin-M".
- "Hamair".
- "Planriz".
Izincomo zokwelashwa kwamafayicide:
- Ukucubungula kwenziwa ngekhefu kwezinsuku ezingu-10-14.
- Kungcono ukuphalaza kusihlwa.
- Amalungiselelo adinga ukushintshaniswa, ngoba i-fungus evuselela lesi sifo, ingasetshenziselwa umuthi osebenzayo ekubunjweni kwendlela ethile.
Kubalulekile! Lapho ukuchithwa kwamakhemikhali kufanele uqaphele izinyathelo zokuphepha. Ukucubungula kwenziwa ngosuku olumile olungenawo umoya. Vikela umzimba nge-suit ekhethekile, amehlo anezibuko, umlomo nomlomo nge-mask.
Ngakho-ke, i-powdery isikhutha ingenye yezifo ezimbi kakhulu ezifakwe yizifo ezitshengiswayo izitshalo eziningi. Ngeshwa, izimbali ezinhle zensimu azifani. Kodwa-ke, uma unolwazi oludingekile mayelana nezimbangela ze-powdery isikhutha kuma roses nokuthi ungabhekana kanjani nalo, ungaligcina engadini yakho ye-rose, ugcine izinyathelo zokuvimbela. Uma kwakungenakwenzeka ukugwema lesi sifo, sebenzisa abalimi abavuthiwe noma amafungicides ahlolwe ngabalimi, futhi ngokuqinisekile uzophambuka ezimpandeni zakho.
