I think you'd get more feedback asking one question at a time. But I think the first question answers all the rest.

What would be the better pesticide to use on crops for farmers?

In my little world, we have used to many forms of un-natural pest control. I grew up in the country... we DID NOT know what pesticides were... Locusts---old brooms,shirts, run, yell... name the intruder, we faced it. There are too many quick fixes with long-term BAD results in this world. Take the time to enjoy your fodder... use Mother Nature's friends. Stop the pollution.
