Aquatic Hemp Grass Has Become a Major Pest – Blame Farmers?

Over 200 years ago, the era of modern agriculture began with fertilizers that would not give you food poisoning if any traces of it remained, as manure will.

A new article has found what you expected and a key reason why older pesticides used in the biological process require almost 600% more chemicals per calorie; pests evolve at the same rate as science.

In their observational study, the authors compared 187 aquatic hemp samples from nearby farms and wetlands with more than 100 herbarium samples, dating as far back as 1828, housed in museums across North America. . They found hundreds of genes in the weeds’ genome that contribute to their ability to compete on farms, with mutations in genes linked to water requirements, rapid growth and even ancient herbicide resistance. They’ve found that a weed once mostly near lakes and streams is now found in drier land – and they blame genetic changes linked to agriculture.

Hemp drains nutrients used for crops like soybeans and corn, so they evolved to continue to do so even as agriculture sought to kill weeds. No wonder that since many samples were taken before herbicides existed, the study found that five of the seven herbicide-resistant mutations found in current samples did not exist in ancient ones. A little more surprising is that two did. If an herbicide does not kill a plant, that genetic ability can be passed on. Thus, the authors noted that water hemp with one of the seven herbicide resistance optimizations had on average 1.2 times more surviving offspring per year since 1960.

It’s no surprise to scientists even the two mutations that had nothing to do with herbicides but still offer resistance. Science knows that just as medicine must evolve as nature finds new ways to kill, pesticides must also continue to improve. If we were stuck with “organic” herbicides like copper sulfate, we’d still be using hoes. The article does not overtly criticize farmers, although academic ecologists do so often that scientists are not wrong if they automatically assume that is the case, but emotional verbiage like “intensive farming” is the farming community’s “white lives matter” phrasing – that’s absolutely signaling its true intent. Because it’s a fake story. In the United States, the overwhelming majority of food is produced by family farms, almost none of which are even large enough to trigger an estate tax. The land is their greatest asset, they value it and use the cleanest solutions. Only academics think farmers are destroying their assets.

As the population approaches 8 billion, the worst thing for affordable and nutritious food would be if regions like Europe continue to penalize poorer countries that need modern technology to be self-sufficient. The fight is ongoing, and herbicide-resistant mutations have also been found in natural habitats, so food production can’t really be blamed, but this study will be used by campaigners touting “mutations.”
