Izimbali zasendlini, kanye nezimbali zensimu, ngezinye izikhathi zigula. Lokhu kwenzeka ngezizathu ezihlukahlukene - inhlabathi empofu, ukuchelela ngokweqile, izimo ezinganele. Isibonelo, ama-violets avame ukugcwala ukulimala okwesikhashana, izibungu, ama-aphid. Bahlushwa izifo ezifayo, ikakhulukazi isikhumba se-powdery. Ake sithole ukuthi singaphatha kanjani izimbali kule nkinga nokuthi singaphatha kanjani ama-violets avela emanzini e-powdery.
Indlela yokuphulukisa i-violet kusuka ku-powdery isikhutha?
Amaqabunga e-violet abathintekile yilesi sifo azoba nokugqoka okumhlophe futhi babonakale benothuli. Kodwa akusilo uthuli nhlobo - kungukugqoka ezimhlophe ze-mycelium. Angakhiwa hhayi kuphela emaqabungeni, kodwa futhi ngeziqu kanye neziqu.
Ukuze ususe ama-violets akho owathandayo kusuka ku-powdery isikhutha, udinga ukuqonda izizathu zalokho okuvela khona. Futhi zingahluka:
- ukunciphisa imbali nge nitrogen ezimweni zokuntuleka kwe-phosphorus ne-potassium emhlabathini;
- umswakama ophezulu ekamelweni lokushisa okuphansi;
- uthuli nokucwiliswa eshalofini enezimbali;
- ukukhanya okwanele kwesitshalo.
Njengomthetho, akunzima ukubhekana nomkhuhlane we-powdery kuma-violets. Kuyoba okwanele ukusebenzisa isitshalo esisodwa sezitshalo ezigulayo nge-agent e-antifungal.

Uma ukufiphaza okulodwa kungakusizi, emva kwezinsuku ezingu-10 ungaphinda inqubo noma usebenzise ukulungiselela okunamandla "I-Topaz".
Ukwelapha isikhumba se-powdery ku-violets kungenzeka futhi izixazululo zomuntu - kulezi zinkinga zokusebenzisa i-calcined soda noma i-copper sulfate nensipho, ukumiswa kwe-sulfur colloidal, ukukhipha imfucumfucu yezinkomo.
Futhi ukuvimbela ukuphindaphinda kwe-powdery isikhutha kuma-violets ngemva kokwelapha, zama ukudala izimo ezifanele zezimbali zakho: gcina ishalofu noma uhlalise ihlanzekile, ugcine umbuso wokushisa futhi uhlinze umquba omuncu ngobuningi obufanele. Beka lezi zitshalo kangcono ezinhlangothini ezisenyakatho-empumalanga. Futhi uma amawindi akho ebheka entshonalanga noma eningizimu, qiniseka ukuthi uthunzi ama violets, ikakhulu ehlobo.
