Depends on who you talk to the ag extension still say 250. The hefty boys I think are around 25 to 50. IMO it matters what time of the season it is if it is early I spray with the hefty boys recommend, because they don't go away and multiply so fast. Later in the season I wait for the higher population to make sure I only have to spray once since most sprays have a residual.
