Abstract: Vegetable growers can reduce
the amount and environmental impact of pesticides used to produce peppers by
growing varieties resistant to bacterial leaf spot (BLS) and using thresholds
for aphids and European corn borer (ECB). IPM demonstrations comparing the use
of thresholds with the grower’s usual practices conducted for the past
three seasons have documented that crop quality resulting from the use of thresholds
is equivalent to that resulting from the grower’s usual practices. Growers
avoided the use organophosphate insecticides up for review by the FQPA in the
IPM area of the demonstration fields. The cost of insect management is higher
when organophosphates are not used than when they are used. Currently, there
are a limited number of non-organophosphate insecticides labeled for use against
ECB control that do not contribute to aphid outbreaks, and no options that control
both ECB and aphids.
