Hit a double digits h-index today. Whether the double-digiti-ness rests on a single shameless self citation in my latest paper is not the question you asked though.

Do you know about bees but want to start looking at pesticides (or know someone who does)? Then why not start with reading our primer - setting out the basics to get started in bee and pesticide research! Led by @edstraw.bsky.social besjournals.onlinelibrary.wiley.com/doi/10.1111/...

If you could stick a bunch of sensors into a bee colony placed out in farmlands, what would you want to measure? I've got temperature, humidity, colony weight and bee entry/exit down, but I imagine there are other metrics that'd be super interesting. Thoughts?

Pesticides are more than just the main ingredient 10 April 2024 Free
Dr Edward Straw of Trinity College writes about how the active ingredient is a small part of a pesticide. Co-formulants which help the product to work are a large part of the ingredients.

Complaint about modern academic papers: Acronyms. Example: Each of these acronyms is only used in this specific table, and there's clearly enough room to expand the acronyms into full text. UAMPHTR,FNBAA: Using acronyms makes papers harder to read, for no benefit at all.
Table with 4 acronyms listed with lots of blank space around then.

If we ended co-formulant secrecy tomorrow, there'd be no negative impacts on industry and researchers would be much freer to ensure that all the ingredients in pesticides are safe. Go read the paper, it's free to read and only 3 pages long. doi.org/10.1016/j.en...

The real outcome of co-formulant secrecy is to limit the ability of independent researchers to understand the toxicity pesticides pose. Both to people, and nature.
110
Ed Straw @edstraw.bsky.social · 21/02/2024
1) Secrecy doesn't work. Rival companies can reverse engineer the formulations (this has been done multiple times). 2) Their innovation is already protected by patents. 3) The public's right to know what's included in pesticides outweighs the company's commercial interest.
110
Ed Straw @edstraw.bsky.social · 21/02/2024
This means farmers don't know exactly what they're spraying, and consumers don't know what the food they're eating has been sprayed with. The pesticide industry argues keeping this as a trade secret protects innovation. This is wrong for three reasons:
110
Ed Straw @edstraw.bsky.social · 21/02/2024
Pesticide labels list the main ingredient in the pesticide, as well as a few of the other ingredients (called co-formulants). But unless a co-formulant meets specific EU rules, it doesn't have to be listed on the label.

Ed Straw @edstraw.bsky.social · 21/02/2024
New Paper! Here I argue that the list of ingredients on the back of a pesticide should no longer be a secret. Secrecy isn't in farmer's or consumer's interests! I also take on the industry arguments defending the practice. 🧪 doi.org/10.1016/j.envsci.2024.103701

Take home: Pesticides in Ireland leave residues in soils, nectar & pollen. They can have impacts on bees, but the level of risk for fungicides and herbicides needs more work. We need better pesticide usage data, & better mitigation measures, to track change and reduce risk 16/16

This is especially important, as farmers are very good at following rules and guidance around pesticide use (except in terms of wearing PPE!). So, the better the rules the better the potential outcomes. doi.org/10.1016/j.ec... 13/16
