Thousands of successful and very profitable organic gardeners/farmers are doing without the pesticides. It requires "relearning" and using other techniques to adjust, but it can be done. Yes, pesticides were simply over done to the point that bugs develop resistance, but residuals of these chemicals are in our water, soils and worse, in our bodies. I am neither an alarmist nor a radical "tree hugger", (whoever those folks are). Just an old country boy.
I grew up commercial farming with chemicals so the necessary adjustments have been challenging, but it can be done, is being done quite successfully. We all just have to re-learn other methods. I am not going to waste my time whining about it, but working my behind off to learn new tricks. I'm an old dog, and if I can do it, anyone can.
