Do you know any common brand name pesticides for garden use?

[derrick c.]

I'm doing a science fair project on brand name pesticides vs. natural pesticides. I need some brand name pesticides that can be applied to plants specifically. If you can, also name some natural pesticides. What I'm trying to do is test which is better for harming pests, brand pesticides or natural.

Thanks in advanced. And no i don't use brand pesticides myself, or so I think.
