The claim that 99% of corn is sprayed with glyphosate is not supported by the sources. Official USDA data show glyphosate applied to about 41% of corn acres in 2021 and Minnesota reports 76% for 2019, and even the highest estimates (EPA and advocacy groups) sit near 80-91%, none near 99%.
This claim is about the present, so it is judged as of the day it was checked.
What was said
… I, you know, I wasn't in there to argue for unreasonable things. We have a very complicated, interconnected economy. I've even buy the argument, right, that we can't ban this stuff tomorrow. You know, 99% of corn is sprayed with that, 98% of soybeans. It's used in other countries. It's a lot less in wheat, which is yeah, and they use it for post yeah desiccation yeah, which is really insane. …
The Joe Rogan Experience · · from the transcriptPost →What we found
Contradicts. USDA NASS's 2021 field crop survey reports glyphosate isopropylamine salt applied to 41% of planted corn acres, and glyphosate is not listed among the top herbicides beyond that salt form.[1]
Contradicts. Minnesota Department of Agriculture data for 2019 report glyphosate applied to 76% of all corn acres in that state, well short of 99%.[4]
Contradicts. A Food & Water Europe analysis of USDA data reports 80% of corn acres treated with glyphosate in 2022, and NBC News describes glyphosate use on 'nearly half' of corn and soybean acres.[3][5]
Contradicts. EPA's review says roughly 90% of corn acres are treated with glyphosate, the highest figure among the sources; this is still below the claimed 99%.[2]
Context. The 99% figure in the post appears to be a different statistic: the Non-GMO Project reports that field corn makes up about 99% of US corn grown, which is a crop-type share, not a glyphosate-use share.[6]
Context. The claim's wording ('sprayed with that') refers to glyphosate in the post, so the extraction is faithful; the 99% figure is the speaker's own number and is contradicted by the record.
