A new easy-to-use tool is being developed to help farmers and plant health authorities quickly detect harmful pests, the viruses they may carry, and signs of resistance to pesticides—all directly in the field. The system uses “pill”-shaped pellets that contain all the necessary chemicals in a freeze-dried form. There’s no need for complicated lab work like DNA extraction. Farmers or technicians just need to add a sample of insects (like mites, thrips, whiteflies, aphids, mealybugs, or psyllids) to the reaction tube, and results are ready quickly using a small, portable device.The same tests can also be used in advanced labs for high-sensitivity results, allowing policy-makers and scientists to confirm findings and monitor resistance on a larger scale.For plant viruses, another part of the platform uses a compact device (qcLAMP) that can detect viruses in crops like tomatoes (e.g., TYLCV, TSWV, ToBRFV) and grapevines (e.g., GFLV, ArMV, GRBV). Users simply place a small leaf piece into a reaction tube—no training required. Results appear automatically on a tablet or smartphone, and data can be saved or shared instantly for early warning and coordinated action. This technology makes on-the-spot diagnosis possible, saving time and helping reduce crop losses. It will support smarter pest control decisions, improve pesticide use, and strengthen surveillance and response systems. Field testing with farmers and plant health services will ensure it meets real-world needs, with the goal of bringing it to market soon (Technology Readiness Level 7).
