The use of Insecticides remains one of the primary methods for controlling species harmful to crops. However, insecticides used for pest control pose hazards to human health and cause environmental damage. Nanotechnology has been used in the agriculture sector to address these problems and increase crop yield. Numerous formulations with various modes of action and applications have been developed, including solid-based nano-pesticides, controlled-release formulations, nanoemulsions and nanosuspensions. Nano-pesticides provide effective and environment friendly substitutes for controlling insect pests in fields and storage. Nanoparticles can be used to target particular pests, thereby minimizing off target impacts and increasing pest control effectiveness. Nano formulations enhance the stability and solubility of active ingredients, leading to better absorption and prolonged action, and also allow for the slow and controlled release of pesticides. Recently, green nanotechnology-based nanoparticles and nanoparticle-based RNA pesticides have been used as a recent trend to control vegetable crop pests. This review presents information about recently used nano formulations for vegetable crop pest management and their challenges.
