A study by Embrapa Medio Ambiente and the University of Rio Verde (UniRV) revealed that herbicide consumption in Brazil increased from 157,500 tons in 2010 to 329,700 tons in 2020, a 128% rise. ^[1] Kevin Bradley, a University of Missouri Extension weed scientist, stated that fall applications of herbicides are far more effective for treating Johnsongrass than spring or summer applications. ^[2] Brazil currently records 20 cases of glyphosate resistance in at least 12 weed species, including Digitaria insularis and Conyza spp. ^[3] According to USDA estimates, Johnsongrass infestations can reduce corn and soybean yields by up to 80%. ^[4] Johnsongrass is listed as a noxious weed in Missouri and many surrounding states. ^[5] Johnsongrass spreads through both seeds and underground rhizomes, with individual plants producing as many as 80,000 seeds annually. ^[6]

Why these sources, and not others

How the desk chose them

We do not pick publishers. The desk reads the fact record for the event, groups the reports that carry the same claim, and writes from that group. Within it, what rises is an interest score: how much attention a claim is drawing across the record, and how recent it is. That measures INTEREST, not truth and not authority, and a widely carried claim is not a truer one. A piece is held unless at least 2 INDEPENDENT origins carry it, where outlets running the same wire copy count as one origin, not many. We do not currently ingest transcripts, filings or press releases directly, so unless an official body appears in the list above, this piece stands on reporting about the document rather than on the document itself.
