Calaamadaha la eegayo
- Baro huruud ah oo aan lahayn qaab sax ah ayaa ka soo baxa dusha sare ee caleemaha yaryar.
- Qaybta Hoose ee caleenta, meelaha baraha huruudda ah ka hooseeya waxaa ka soo baxa caaryo buluug ah.
- Baruhu way sii fidaan, waxay isu beddelaan midab Madow ah, way engegaan, caleemuhuna way duuduubmaan ama qaabkoodii saxda aha way ka bedelmaan.
- Dhirta uu ku badan yahay cudurku way gaabiyan koritaanka ama way dhintaanba
- Badanaa calaamaduhu waxay so baxaan 7-10 maalmod ka dib, aadna wu u fidaa cudurku.

Hab-beereedka
Isticmaal noocyo dhirta ee u adkaysta cudurka. Isticmaal siidh nadiif ah, kana fogow waraabka caleemaha qoynaya. Dhirta meel u kala fogee si hawadu u dhex marto, hana u beerin si aad u cufan. Ka saar dhirta cudurka qabta iyo hadhaaga beeraha, sameena dalagg gedis (crop rotation).Habka ugu muhiimsan ee looga hortago cudurka waa in caleemaha laga ilaaliyo qoyaanka badan ee muddada dheer.
Xulashooyinka dabiiciga ah
Isticmaal noocyada dhirta ee cudurka u adkaysta. Hagaaji hawo socodka beerta, kala fogee dhirta, ka fogow waraabka caleemaha qoynaya, kana saar dhirta cudurka qabtay. Copper fungicides sida copper hydroxide iyo copper oxychloride waxay caawin karaan ka hortagga cudurka.
Waxyaabaha firfircoon
- copper hydroxide
- copper oxychloride
Xulashooyinka kiimikada
Waxaa loo isticmaali karaa fungicides gaar ah sida mandipropamid, dimethomorph, iyo phosphorous acid. Daawooyinka waa in la isticmaalaa ka hor inta cudurku si weyn u faafin, waana in la beddelaa noocyada daawooyinka si cudurku uusan u yeelan iska caabbinta.
Waxyaabaha firfircoon
- mandipropamid
- ametoctradin
- dimethomorph
- phosphorous acid (phosphonate)
Badbaadada
Marka la isticmaalayo daawooyinka, xidho galoofisyo, masks iyo murayadaha indhaha. Raac muddada sugitaanka ka hor goosashada ee ku qoran daawada. Caleemaha isbinaajka si fiican u dhaq ka hor cunista.
Sidii looga hortagi lahaa xilliga soo socda
