profit, only Baythroid dominates Penncap M in
terms of EV analysis.
As indicated when discussing the field experi-
ments, in Florida in 1989, a sub-threshold insecticide
application was applied. This resulted in the control
as the only SSD efficient insecticide for Florida
profit in 1989 and the control along with Karate and
Baythroid in the risk efficient set associated with
yield. Applying insecticides at a sub-threshold level
might have reduced the positive effects on yield of
beneficial insects and spiders. However, not apply-
ing an insecticide to control for stink bugs, which
feed directly on the soybean seed, resulted in a higher
