Green guardians: Harnessing biopesticides for sustainable vegetable pest management

Insect pests pose significant challenges to vegetable crops, causing not only economic losses but also compromising the quality of our food. Shockingly, up to 20 % of globally produced goods fall victim to these insidious invaders. While chemical insecticides have historically bolstered food production, they come with notable drawbacks, including handling risks, residue concerns and negative impacts on non-target species and the environment.Though they have not yet completely replaced chemical insecticides, biopesticides are becoming key in reducing pesticide overuse and promoting safer, residue-free food and environments. Derived from plants and microorganisms, biopesticides offer a safer alternative, ranging from plant extracts to microbial agents such as bacteria, fungi, viruses and nematodes. Additionally, insect hormones and semiochemicals, along with silica-based mineral products like activated clay and rice husk, contribute to eco-friendly pest control solutions. Cutting-edge nano biopesticides also deliver unparalleled pest control with precision targeting and excellent environmental credentials.In this comprehensive exploration, we delve deep into the myriad forms of biopesticides, their commercial availability, modes of action and the advantages and disadvantages in vegetable pest management. Crucially, we illuminate the path toward integrating biopesticides into holistic pest management strategies, which can lead to healthier crops, increased yields and more sustainable agricultural practices. By emphasizing biopesticides, we can promote environmental safety and support a greener future in agriculture.
