Field efficacy of a bioherbicide mimic (DiS-NH2) in a nanoparticle formulation for weed control in durum wheat

Abstract

Weed-resistance phenomena have increased dramatically in recent years. Bioherbicides can offer a sustainable alternative to chemical weed control but they often have low water solubility and therefore low efficacy in the field. The research reported here represents the first study on the field efficacy against weeds of a nanoencapsulated bioherbicide mimic of aminophenoxazinones, namely DiS-NH₂ (2,2′-disulphanediyldianiline). Field experiments were carried out across three different locations to evaluate the bioherbicide disulphide mimic at standard (T1, 0.75 g m⁻²) and double (T2, 1.5 g m⁻²) doses when compared to no weed control (NC) and chemical weed controlled (PC) in durum wheat.
