1. Izimpawu
Isifo samaqabunga aphukile silimaza isihloko noma unqenqema lwamaqabunga kagwayi.Izilonda azimile kahle, zinsundu, zixutshwe namachashaza amhlophe angavamile, okubangela amathiphu amaqabunga aphukile kanye namacele amaqabunga.Esigabeni sakamuva, amachashaza amancane amnyama ahlakazekile ezindaweni zesifo, okungukuthi, i-ascus ye-pathogen, kanye namachashazi afile afana nombani ompunga-omhlophe avame ukuvela emaphethelweni emithanjeni phakathi kwamaqabunga., izindawo ezinezimbobo eziphukile.
2. Izindlela zokuvimbela
(1) Ngemva kokuvuna, susa udoti namaqabunga awile ensimini futhi uwashise ngesikhathi.Guqula umhlaba kusenesikhathi ukuze ugqibe izinsalela zezitshalo ezigulayo ezisakazeke ensimini ekujuleni kwenhlabathi, utshale ucinene, futhi wandise umanyolo we-phosphorus ne-potassium ukuze ukhuthaze ukukhula kwezitshalo zikagwayi futhi uthuthukise ukumelana nezifo.
(2) Uma isifo sitholakala ensimini, sebenzisa izibulala-zinambuzane ukuvimbela nokulawula insimu yonke ngesikhathi.Ngokuhambisana nokuvimbela nokulawula ezinye izifo, ama-ejenti alandelayo angasetshenziswa:
Carbendazim 50%WP 600-800 izikhathi liquid;
Thiophanate-methyl 70%WP 800-1000 izikhathi liquid;
Benomyl 50%WP 1000 izikhathi liquid;
Uketshezi oluphindwe ka-2000 lwePropiconazole 25%EC + 500 izikhathi zoketshezi lweThiram 50%WP, fafaza ngokulinganayo ngesibulala-zinambuzane esingu-500g-600g ngamanzi angu-100L ngo-666m³.
