W latach 2003–2004 prowadzono w Boninie doświadczenia z wykorzystaniem nawozów dolistnych do ograniczania rozwoju alternariozy na roślinach ziemniaka. W doświadczeniu oceniano 6 różnych wariantów ochrony. Najwyższą skuteczność w ograniczaniu rozwoju choroby uzyskano dla wariantu 2 × Basfoliar 12-4-6 w dawce 2,0 l/ha (86,0%) i 2 × ½ ochrony (dawki zmniejszone o 50%) + Basfoliar 12-4-6 w dawce 2,0 l/ha (85,3%).
