Nanocomposite based slow release atrazine effectively controlled Striga asiatica incidence, and enhanced sugarcane yield.

ABSTRACT: Sugarcane is a major industrial crop highly susceptible to parasitic weed (Striga spp.), causing a 38% reduction in cane yield due to a longer lag phase of 20-40 days, and wider spacing. Herbicides with a longer retention and slow-release nature could allow Striga seeds to germinate and be killed before attaching to the host. Therefore, a graphene oxide based nanoformulation loaded with atrazine was synthesized and evaluated under controlled and field conditions for its release kinetics, Striga control efficiency (SCE), and cane yield for two years (2018-2019) at two locations. In-vitro assays on release kinetics showed that the release rate of active ingredient (a.i.) from the nanocomposite loaded with atrazine (NCA) was slower (64.5%) than conventional atrazine (82.1%) on the 30th day in
