Commercial planting of genetically modified maize lowers pest damage, yield loss and pesticide usage in Northeast China.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundLepidopteran herbivores and weeds greatly constrain the productivity of maize globally. Genetically modified (GM) maize lines expressing insecticidal cry genes and herbicide-tolerant epsps genes are widely adopted in the continental America, but their uptake is restricted in many parts of the other countries. Northeast China, which is the largest maize planting area of the country, GM maize with both Bt insecticidal and herbicide tolerance genes was commercially released in 2021 and its cultivation reached 250 000 ha in 2023. Here, we investigated the performance of GM maize in terms of pest damage, yield loss and pesticide usage, amongst other metrics, to assess the safety and benefits.
resultWe show how GM maize achieved >99% control of the locally prevailing lepidopteran pests and permitted 97% herbicidal weed control over a 3-year period. As compared to non-GM maize, GM maize yields increased by 4.6-10.1%, mycotoxin contamination levels were reduced by 91.7-95.6% and farmers' net income (under subsidized seed prices) rose by US$276-332 ha
conclusionOur work underlines how GM maize curbs pesticide use intensity, upholds food security and allays food safety concerns. When tactically paired with biological control and the agroecological components of integrated pest management, GM maize could provide durable crop protection and shrink the environmental footprint of agriculture in China. © 2026 Society of Chemical Industry.
