Amayeza okubulala izinambuzane kunye nezitshabalalisi: Imbali emfutshane

Eli yayilixesha eliyimbali kuba eli yayilithuba lokuqala lokuyilwa kwezibulali-zinambuzane nezitshabalalisi ezaziyilelwe ngokukhethekileyo ukulima.
Indlela Amayeza okubulala izinambuzane kunye nezitshabalalisi ezitshintshe ngayo ukulima
Ezi zibulali-zinambuzane zitsha zokwenziwa kunye nezibulali-zinambuzane zabuguqula ubomi bamafama. Ngaphambili, bekufuneka basebenzise amayeza endalo kunqabile permetrine basebenze kakuhle njengoko bebenethemba.
