摘要：

"Mitigating pesticide effects will require multiple approaches. Chemical pesticides should be progressively replaced with agroecological measures such as invertebrate biological control agents and biopesticides, many of which are cost-effective, environmentally sound, and practicable (5). Preventative pest management without chemical pesticides can include planting pest-tolerant varieties (6); using light, pheromone, or sticky traps (7); removing pest resources, such as harvest residues and alternative host plants; and altering sowing dates (8). Other strategies include diversifying crops through intercropping or cover cropping; mulching or organic manuring; establishing flower strips that provide food for predators and parasitic wasps; and raising aquatic animals, such as fish, ducks, or frogs, in cropping fields, where they can prey on insect herbivores or weeds (9).Precision agriculture and digital tools could also decrease pesticide use. Robotics, unmanned aerial vehicles (UAVs), artificial intelligence–based computer vision, and data-driven forecasting or advisory systems can all enable timely, targeted interventions (10). Tractor-pulled or autonomous camera–equipped mechanical weeders, for instance, can surgically remove weeds from a standing crop, and UAVs can “precision-drop” natural enemies or deliver biopesticide patch sprays on infestation hotspots. However, the funds and training required to use such technologies limit their accessibility and impact."
