Lesi sifo esingathandeki sikhathaza abalimi abaningi, ngoba ngaphansi kwezimo ezingavumelekile, isibonelo - ehlobo elivuthayo futhi elipholile, lifika cishe kuyo yonke indawo.
Umkhuhlane we-powdery yisifo se-etiology yamafungula. Kubangela ukubukeka kombukiso omhlophe noma obomvu ngemuva kwamaqabunga, okuholela ekusomeni kwawo. Esimweni esingenakiwe, i-fungus igula iziqu, izimbali nezithelo zamakhukhamba. Ukuvimbela imifino enjalo ukuze ungene kuleli zwe, udinga ukwazi kusengaphambili indlela yokubhekana ne-powdery isikhutha ngamakhukhamba.
Ukwelashwa kwamakhukhamba avela ku-powdery isikhutha
Kubaluleke kakhulu ekuqaleni kwesifo ukuyeka ukusakazwa kwayo. Ngalesi sigaba, izindlela zomuntu zokulwa zingasetshenziswa:
- izimbali zemifino - izimbali ezichotshoziwe (isigamu ibhakede) kufanele zifakwe emanzini afudumele (gcwalisa ibhakede emgqeni) zingakapheli izinsuku ezimbili bese ufaka isobho lokuhlanza (40 g) kwisisombululo esinamandla;
- i-decoction ye-horsetail - eyomile (100 g) noma i-freshtail (1 kg) ye-horsetail ngamanzi (10 l) ngosuku, bese ubilisa amahora angu-1-2, upholile, usebenzise futhi usebenzise emakethe angu-1: 5;
- i-mullein - ngesilinganiso se-1: 3 siphucula ngamanzi, sisho izinsuku ezingu-3 nezikhathi ezintathu zihlanjululwe ngamanzi ngaphambi kokusetshenziswa.
Zonke lezi zindlela zidinga ukuhlanza ngokucophelela ikhukhamba kanye ngesonto ize izimpawu ziphele. Kodwa uma i-powdery isikhutha kwikhukhamba isivele ithuthukile ngokwanele, futhi amalungiselelo emvelo awazisizi, izindlela zokumakhemikhali zisetshenziswa. Lezi yizi:
- isisombululo soda ash (0.5%) nesepha;
- isixazululo se-Bordeaux liquid (1%);
- isisombululo se-sulfate esinawo (5%).
Ukunakwa ngokuphelele i-powdery isikhutha samakhukhamba uphathwa ngamakhemikhali anobuthi. Kuphela kuphela okungasetshenziswa uma kungenasifo sezithelo. Phakathi kwezidakamizwa ezintsha, isisombululo "seKaratan" sihlanjululwe ngamalitha ayi-10 amakhophi amanzi. Udinga ukucubungula njalo ngesonto noma ezimbili.
