Regional pest suppression associated with widespread Bt maize adoption benefits vegetable growers
Open accessAbstract
Significance Area-wide Bacillus thuringiensis (Bt) adoption suppresses pests regionally, with declines expanding beyond the planted Bt crops into other non-Bt crop fields. The offsite benefits to vegetable crops from such pest suppression have not been documented. We show that widespread Bt field corn adoption is strongly associated with marked decreases in the number of recommended insecticidal applications, insecticides applied, and damage to vegetable crops in the United States. These positive impacts to growers, including organic producers, in the agricultural landscape expands on known ecological effects of Bt adoption.

Bt crops can reduce target pest populations over broad scales, resulting in reduced damage on both GE and non-GE crops in the region.
“There is evidence that Bt crops can reduce target pest populations over broad scales (Carrière et al., 2003;Dively et al., 2018;Hutchison et al., 2010;Wan et al., 2012;Wu et al., 2008;Zhang et al., 2018) resulting in reduced damage on both GE and non-GE crops in the region.”

A similar 'halo' effect of lepidopteran suppression by widespread adoption of Bt maize in the eastern USA has been documented, as well as benefits of pest declines in surrounding vegetable fields.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
