Evaluation of a lignin-encapsulated nootkatone formulation against Tetranychus urticae (Acari: Tetranychidae)
Botanical-based miticides, such as neem oil, are used in organic and conventional agronomic production as part of chemical rotation plans to suppress pest mite populations. Other plant-based compounds such as nootkatone (a component of essential oils distilled from grapefruit, Citrus paradise Macfay...
