Isityalo esinokugula kufuneka siphathwe ngesinye sezicombululo ezilandelayo:
- i-manganese-acid - ii-2.5 gram ze-manganese nge-10 ilitha amanzi;
- i-soda calcined kunye nesepha - i-50 grams ye-soda, 40 amagremu yesepha nge-10 ilitha amanzi;
- i-garlic-garlic-15 amagremu we-garlic oqoshiwe ukugxininisa kwi-1 ilitha yamanzi emini;
- amalungiselelo esekelwe kwisulfure okanye ukupilisa ngemithi isityalo esinokugula;
- Ukulungiselela i-Topaz, i-Dectra, i-Skor, njl.;
- umxube we-antibiotics - i-tarramycin, i-penicillin kunye ne-streptomycin kwiindawo ezilinganayo.

Nangona kunjalo, khumbula ukuba unyango lwe-powdery mildew kwizityalo zasendlini kunye nezilwanyana zomntu zisebenza kuphela kwiimeko xa isifo singakhange sisasaze kwaye ubuninzi bomonakalo buncinci. Ukuba ubona ukuba iintyatyambo zibethe kakubi, kuya kufuneka usebenzise "izixhobo ezinamandla" - i-fungicides (Hom, Topaz, Vectra, Skor, Tiovit).
Kule nto kubaluleke kakhulu ukusingatha, ngokulandelelana ngokulandela imiyalelo kunye nokuqwalasela zonke izicwangciso ezichazwe kumyalelo kumalungiselelo. Zonke zizalwe emanzini amaninzi, ngoko ke unokuhlukanisa i-ampoule enye kwizicelo ezininzi.
Ukuthintela isikhumba se powdery
Iindlela zokuthintela zivela kwizizathu zokuphuhliswa kwesi sifo. Ukuba kuthethwa ukuba,
Kwakhona, ukwenzela ukukhusela ukuphuhliswa kwesi sifo, ukuguqula ngokukhawuleza umhlaba, ukuwukhubaza, nokuwunqumla amaqabunga ezityalo. Ukuba kukho izilonda ezincinci, kufuneka zisuswe ngokukhawuleza kunye namaqabunga okanye amaqabunga, thintela ukutshiza eso sityalo kunye nokufumana amanzi kumaqabunga ayo.
Akukho nto inzima kwonyango kunye nokuthintela isikhumba se-powdery, into ephambili kukuba kuqhutywe rhoqo kwaye kuqhutywe zonke iinkqubo eziyimfuneko kude kube yilapho isityalo sinyanga kwaye asiyi kuqhubeka nokuyizisa kwimeko enjalo.
