Esi sifo esingathandekiyo sikhathazeka ngabalimi abaninzi, kuba phantsi kweemeko ezingafanelekiyo, umzekelo - kwihlobo elipholileyo kwaye lipholile, liza phantse kuyo yonke indawo.
Isifo somnyoba sisifo se-etiology. Yibangela ukubonakala kwengubo emhlophe okanye ebomvu emacaleni emacembe, ekhokelela ekumiseni. Kwiimeko ezinokunyanzelwa, iifungus infects iziqu, iintyatyambo neziqhamo zamakhukhamba. Ukuthintela loo mifuno ukuba ungangeni kweli lizwe, kufuneka uqonde kwangaphambili indlela yokujongana nomoya we-powdery kwiikomkom.
Unyango lweemkhukhamba ezivela kwi-powdery mildew
Kubaluleke kakhulu ekuqaleni kwesi sifo ukuyeka ukusabalala kwayo. Kule nqanaba, iindlela zomntu zokulwa zingasetyenziselwa:
- I-tincture ye- marigolds - iindidi ezichotshoziweyo (i-half bucket) kufuneka zifakwe emanzini afudumele (gcwalisa ibhakethi kwi-brim) kwisithuba seentsuku ezimbini kwaye wongeze isepha yokuhlamba (40 g) kwisisombululo esincinci;
- i-decoction ye-horsetail - eyomile (100 g) okanye entsha (1 kg) yokuthengisa i-horsetail (10 l) ngosuku, ubilise iiyure eziyi-1-2, ukupholisa, ukuxhatshazwa kunye nokusetyenziswa kwi-concentration ye-1: 5;
- i-mullein - ngokulinganiselwa kwe-1: 3 kuhlambulula ngamanzi, ukugxininisa iintsuku ezintathu kunye namaxesha amathathu ahlanjululwe ngamanzi ngaphambi kokusetyenziswa.
Zonke ezi zinto zifuna ukucoca ngokucokisekileyo ikhukhamba kanye ngeveki de ivele impawu. Kodwa ukuba i-powdery isikhutha kwikhukhamba sele ikhulile ngokwaneleyo, kwaye amalungiselelo emvelo ayinakunceda, iindlela zokusebenzisa umzabalazo zisetyenziswa. Ezi zi:
- isisombululo soda ash (0.5%) kunye nesepha;
- isisombululo se-Bordeaux liquid (1%);
- isisombululo se-ferrous sulfate (5%).
Ukunyanzeliswa ngokupheleleyo kwesikhumba se-powdery yamakhukhamba uphathwa ngeekhemikhali ezinetyhefu. Ziyakwazi ukusetyenziswa kuphela kuphela ukuba kungabikho i-ovary yeziqhamo. Phakathi kwamachiza amatsha, isisombululo se "Karatan" sihlanjululwe kwiilitha ezili-10 zamanzi ngokufanelekileyo. Kufuneka usebenze ngeveki okanye ezimbini.
