What other methods do you employ in IPM?
I think you need to do some reading. What 'IPM' stands for, as a start. First and last words are important (no point in doing anything if there is no problem, for a start).
Organo-phosphates and others are actually organic compounds. Chemicals are combinations of elements in fixed proportions, so both thymol and oxalic acid are, indeed, chemicals. Organic chemistry is the study of carbon chemistry, as opposed to inorganic chemistry,. Question might arise as to whether limestone is 'organic', of course!
But nevermind, I don't think there have been many un-flawed polls on the forum previously. A simple 'yes' or 'no' to a single simple question is about the best way to have an un-flawed poll. Multiple irrelevannt options are the worst.
