Are Copper-Based Nanopesticides For Tomato Crops Worth It?

By Hussain AhmedJul 21 2022Reviewed by Megan Craig, M.Sc. The tomato plant is the second most important global food product after potatoes. However, a broad range of diseases significantly reduce its yield. A recent study published in the journal ACS Agricultural Science & Technology presents a thorough evaluation of the efficacy of copper-based nanopesticides for tomato disease management.

Early blight, induced by Alternaria solani , is one of the most devastating tomato plant diseases. It can develop at any phase of the plant development cycle and reduces tomato fruit harvests by 50 to 86 percent. In recent years, fusarium wilt, caused by the soil-borne fungus Fusarium oxysporum , has resulted in a 10-80 percent output loss in tomato cultivation.

Related StoriesTraditional chemical pesticides are also efficient in plant disease management, but their overuse pollutes the environment and creates serious health hazards. Furthermore, long-term usage of traditional chemical pesticides promotes disease resistance and raises economic costs. Nanoparticles have a substantially higher surface-to-volume ratio, improved absorption, and chemical bonding compared to bulk-sized particles. These features enable nanopesticides to deliver drugs more efficiently in tomato plants. Furthermore, unregulated absorption of conventional pesticides can impede plant development owing to phytotoxicity.

As a result, a complete comparison of the effectiveness and cost of nanopesticides and traditional pesticides against tomato diseases is required. This research can assist in identifying the technical and economic benefits of nanopesticides over conventional pesticides. Key Developments of the Study From a technical standpoint, the findings suggest that copper-based nanopesticides outperform traditional copper pesticides in terms of effectiveness, resource efficiency, and biomass production. Copper-based nanopesticides were shown to be as cost-effective as traditional pesticides, indicating their viability for large-scale applications.
