If you buy chems at full price, they will bend over back to help.  Problem is that might be 5,10-20k per year.  If you are paying 1/4 of their salary with inflated prices they better be there.

I'll put the cash in my pocket, if I have to respray or it doesn't work as well as expected, I'll cover the product need for respray and not use the product next year. Generic chemicals have changed the cost structure dramatically.
For example.  Callisto was 500 a gallon.  Generics came out for 100/gallon.  That is a savings of $9 per acre.  I remember reading callisto was used on at least a third of the acres nationally.  That is over 270 million dollars that farmers could have saved.
