Evaluating hidden risks of herbicides over multiple generations
Robert Brucker grew up in rural Ohio, where farmers depend on herbicides to protect crops. Now in his lab in the Microbial Sciences Initiative at the Rowland Institute of Harvard, he studies how agrochemicals affect insects over multiple generations. “It’s important to recognize that the pesticides and herbicides we use are essential for our food security, and that following best practice in pest management is an essential part of life,” said Brucker, who is a Rowland fellow. “But now that we’re starting to understand the role of microbes in health, it’s time to look carefully at the impact these compounds have not only on cytotoxicity, but also on the microbiomes of pollinators and even ourselves.” Robert Brucker researches how the gut microbes of wasps, when exposed to a widely used herbicide, leads to changes in the gut microbiome that are passed to future generations.
