Sažetak
Pathogenic microorganisms, including fungi, oomycetes, bacteria, viruses, and viroids, constitute a serious threat to agriculture worldwide and are one of the biggest threats to global commercial crop and food production resulting in significantly increased cost of production, reduced crop establishment and productivity One of the main challenges of modern agriculture is the preparation of new agroecological formulations for the protection of plant crops based on silver and zinc ions. The aim of this investigation is to explore how the method of ionic-gelation encapsulation method can produce biopolymer microcapsules enriched with silver and zinc ions, which could increase the stability and viability of silver and zinc ions over a longer time period. At the optimal point microcapsules enriched with silver and zinc ions were produced and physiochemically characterized (microcapsules size, encapsulation efficiency, loading capacity, particle size). The process of encapsulation in biopolymer microcapsules did not have a negative impact on the properties of the silver and zinc ions and its activity remains very high. Also, the silver and zinc ions release data were fitted to the Korsmeyer- Peppas model and the n exponent indicated that the release mechanism was Fickian. The electrostatic interactions between silver, zinc ions, alginate and chitosan were confirmed by infrared spectroscopy. The obtained results showed that silver and zinc ions could be successfully encapsulated and applied in the process of plant protection against plant pathogens.
