All pesticides are registered by an EPA issued number, and its uses are guided by a label, which is the letter of the law when it comes to application procedures. These uses are periodically reviewed, and environmental risks assessed based on ‘new’ science that becomes available.
What I’m saying is this process didn’t change during the Trump administration.
As an example, the complete revocation of the insecticide chlorpyrifos was initiated during the Trump administration. The revocation went into effect in 2021. It was then found the EPA violated some procedures and chlorpyrifos was allowed back on the market during the Biden administration while the EPA allowed for a public comment period. After that period, chlorpyrifos was allowed and will be registered on 11 crops going forward, but wont have the widespread label allowances it previously had.
Long story short, the way the EPA went about its business changed very little (at least in regards to pesticide regulation) during the Trump administration.
If RFK Jr does some of the things he’s talking about, we may see huge changes in this administration. I guess we’ll see.
