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%).
In the work the features and properties of press cake obtained in industrial processing of raspberries and strawberries on juice concentrates, which could be useful in taking business decision connected with using such materials in practice, have been presented. It was demonstrated that industrial strawberry and raspberry press cake containing high quantity of proanthocy-anidins and ellagitannins with relatively low pesticide residues, could be used for production of extracts, which are characterized by over 80% effectiveness in protecting tomato and parsley against dangerous diseases: early blight, powdery mildew and potato late blight.
