Iqoqo lokubalulekile

Izinambuzane ezilimazayo kakhulu zamagrebhisi ewayini, izimbungulu zemivini, ubhungane, nezintuthwane. Lezi zinambuzane nazo zibe nobuhlobo obuseduze nomunye ngoba ukulawulwa kwamakhemikhali kungabulala izitha zemvelo zazo.Lezi zinambuzane kumele zilawulwe ndawonye.

Izinambuzane eziningana zenzeka esivinini kanti izinambuzane ezilandelayo ngezinye izikhathi zingase zibe inkinga:

I-Phylloxera
Nematodes
Ama-margarodes noma amaparele omhlaba
Imbungulu zamagilebhisi
Izintuthwane
Ubhungane
Isibungu sokuhluma
Isibungu se-Erinose
Iminenke
Iqhwagi

I-Phylloxera

I-Phylloxera yimbungulu encane ehlala emhlabathini futhi idla izimpande zemivini. Isebenza ikakhulukazi ngoMandulo kuya kuNhlaba. Ngaphansi kwezimo ezithile, kungazondla amaqabunga futhi kubonakala njengenduku engaphansi kweqabunga Ukumbulula nokucwaninga izimpande zemivini ebuthakathaka kungabonisa izinambuzane eziphuzi ezinxenyeni ezilimaziwe zezimpande. I-Phylloxera ibonakala emhlabathini osindayo njalo imivini engahlumelisiwe iyazwela lezi zinambuzane. Indlela ejwayelekile kakhulu yokulawula ukusebenzisa izimpande ezibekezelayo ezifana ne-Ramsey.

Ama-Nematodes mancinyane futhi alimaza izimpande zemivini. Amanye ama-nematode ahlala ngaphakathi empandeni futhi angabangela isixuku sempande, kanti amanye ahlala kuphela emhlabathini futhi ahlasele izimpande ngaphandle. Ukulawulwa kwamakhemikhali kufanele kucatshangelwe emva kokuhlaziywa kwenhlabathi kanye nezimpande futhi kufanele kusetshenziswe njengoba kuqondisiwe.

Njenge-phylloxera, izimpande ezithintekayo ze-nematode nazo zingasetshenziswa. Izitshalo ezithile zokumboza ezifana ne-African marigolds kanye ne-oilseed radish (i-Raphanus sativus subsp. I-Oleiferus) zinomthelela wokucindezela amanani we-nematode. Umuthi wokubulala amaNematode ngokuvamile uyingozi kakhulu futhi kufanele uphathwe ngokunakekelwa njalo ngaphansi kokuqondiswa.
