From what I'm aware of, the pesticides now being reviewed would actually increase if they were decertified or taken off the list of products available to me. I would probably have to spray other things that are more harmful to the environment and use up more of my time, fuel, and effort. It would make my job that much more difficult. Right now there are risk management strategies for dealing with certain insects that affect certain crops. The most common crop that would be affected is canola, which is my go-to crop.
There's a particular insect that is there when the crop comes out of the ground, generally, and if you miss that two-day window of spraying it when it comes up, you're done.
It would be quite costly, not just to me, but to the environment as well.
