Iphunga le-Mealy (ngamanye amazwi, umlotha noma umlotha) yisifo esiwufungayo esibangelwa isikhunta esincane kakhulu esiphila enhlabathini - umyalelo we-powdery erysipelas noma i-erysiphoid. I-Currant ihlushwa yi-fungus. I-mealy idonsa ingxenye yesitshalo esingaphansi komhlabathi - amaqabunga, ama-petioles, amaqabunga, izithombo kanye namahlumela kulo nyaka, kanye nephuzu elikhulayo. Ake sihlolisise lesi sifo kanye nezinyathelo zokulwa nazo.
Yini eyingozi futhi ivelaphi
Lesi sifo siqala ukusakazeka ekuqaleni kukaJuni, isigaba esisebenzayo senziwa ngoJulayi - Agasti. I-agent causative yi-fungus Lalela Funda Kudivayisi kuphela Kwengeziwe Buka Kufakiwe Sphaerotheca morus-uvae Berk, et Curt.
Azikho izinhlobo ze-currants eziphikisana ngokuphelele nalesi sifo. I-fungus ikhiwa emaqabunga, ama-petioles, amahlumela amancane, amajikijolo nama-stalks zezitshalo. 
Okokuqala, isikhutha se-powdery sithinta amaqabunga namahlumela asondelene nomhlabathi, bese kuthi sonke isitshalo sitheleleke kuso. Lesi sifo se-currants kufanele sicatshangelwe ngokucophelela esithombeni ukuze sikwazi ukuhlukanisa nabanye.
Uyazi? I-Currant i-Pantothenic acid (i-vitamin B5), eyenza i-immununity iphinde ikwazi ukumelana nemithi, futhi iphinde ithuthukise isimo sesikhumba nezinwele.Ekuhloliseni okusheshayo, uzobona izilonda, ezisezindaweni zokunamathiselwa kwe-mycelium. Ngenxa yalokho, lesi sitshalo sinciphisa futhi singathandeki, njengoba i-fungus ivimbela ekudleni, futhi i-photosynthesis ihlaselwa emaqabunga aphethwe.
Ngesikhathi esifanayo, imifantu ibonakala izithelo ezigulayo, ezingase zithatheleleke nge-pathogens of rots. 
I-fungi iba esebenzayo ngaphansi kwezimo ezilandelayo.:
- ngezimvula ezinkulu;
- ekushiseni kwemoya + 15-27 ºC ngokumelene nesizinda somoya umswakama we-60-80%;
- enezinguquko eziningi zokushisa;
- emva kokudubula okunzima kokuguga;
- nge-nitrogen ngokweqile emhlabathini;
- uma amahlathi ayehlwanyela kakhulu;
- nemodi yokuphuza engalungile. Isibonelo, ngokugcoba njalo komhlaba noma ngokuchelela okungavamile.
Izimpawu zokunqotshwa
Nazi izibonakaliso eziyinhloko ongazi ukuthi isihlahla se-currant sinegciwane le-powdery:
- Ukuqhakaza okumhlophe kunamaqabunga namahlumela, okuzokwenza kube mnyama esikhathini esizayo.
- Iphuzu lokukhula liyabathinteka, lesi sitshalo saphela ukukhula nokuwa.
- Amaqabunga ama-curl, anciphisa usayizi, futhi alahlekelwe nombala wabo obuluhlaza.
- Amajikijolo, ayenesikhathi sokubumba, ayembozwa ngokuqhakaza, kanti labo ababengabonwanga bewile.
- Isihlahla siyeka ukukhula, soma, ukumelana kwayo nesithwathwa kunciphisa. Ngakho-ke, uma i-currant ingafi ngesifo, khona-ke ngeke nje isinde ebusika.

Kubalulekile! Uma isimo sezulu sikhuthaza ukuthuthukiswa kwezifo ze-fungal, kuyadingeka ukuba sikhule izinhlobo eziningi ze-currants ezingamelana nazo, isibonelo, iNdove, Black Pearl, Agat, nabanye.Ekuqaleni kwentwasahlobo, amahlathi nezihlabathi kudingeka baphathwe ngesisombululo samavitriol.
Futhi, hlola ngezikhathi ezithile izihlahla ukuze uhlole ngokushesha lesi sifo, ngoba ngokushesha uma uyibona, amathuba okudinga ukwelapha isitshalo. Ngalendlela, ungabona ukuthuthukiswa kwezinye izifo ze-currants.Indlela yokulwa
Kubalulekile ukuphawula ukuthi isikhumba se-powdery sitholakala emakhaleni amhlophe namabomvu kaningi kunokuba kube omnyama. Izinyathelo zokulwa nesifo zihluke kakhulu. 
Ungaphatha isitshalo esinegciwane kokubili ngosizo lwama-fungicidal amalungiselelo (uma usebenzisa, landela imiyalelo yomkhiqizi) futhi ngosizo lwamakhambi asebenzayo abantu.
Isifo sithinta izitshalo eziningi, njenge: utamatisi, ama-apula, amagilebhisi, ukhukhamba, ama-roses, i-gooseberries, ama-raspberries, i-peas, ama-strawberries, i-viola, i-orchid, i-gorteniziya, ama-violets, ama-houseplants.

Ngakho-ke, uzothola umphumela ofanayo nokunisela zonke izingxenye zasemahlathini.I-powdery isikhutha esihle kakhulu sokulungiselela ama-currants:
- Isixazululo se-3% se- "Nitrafen". Ukucubungula izitshalo nale mithi ekuqaleni kwentwasahlobo noma ekwindla zakuqala.
- Ngaphambi kokuvela efihlekile ekuqaleni kwentwasahlobo, kunisela izihlahla kanye nomhlabathi ngaphansi kwazo ngesisombululo sulfur sulfate (80 g ngalinye ngamalitha ayi-10 amanzi).
- Isixazululo se-1% se-sulfur colloidal, 0.1-0.2% "iKaratan", i-lime-sulfur decoction, inqaba 1 ngokusho ku-Baume. Ukwelashwa kokuqala ngaphambi kokuchichima, okwesibili kufanele kwenziwe ngaphambi kokwakhiwa kwe-ovary, kanti okwesithathu - emva kwesonto nengxenye.

- Ukumnika uketshezi we-anyanisi, okufanele ukwelashwa esigabeni sokuqala sesifo. Futhi kufanelekile njengesilinganiso sokuxwayisa;
- 25 g we-sulphate yethusi + 25 g insipho, isisombululo sika-1-3% se-aqueous.
