Sorry, Marjorie. Not how it works here. Almost all farmers spray on a
regular
program because that's what the pesticide rep. (probably the only
advisor they've
got) told them to do. The pesticide rep. is only doing what he is
trained and paid
to do. The local ag. extension people are (mostly) in no better posion.
