Since the Plant and Pest Advisory Newsletter, Vegetable
edition is not being sent today, what follows is a shortened version of the IPM
Update which normally appears in it.
European corn borer
– State wide captures in traps are very low.
Highest catches, still less than 1 per night occur in Gloucester and
Cape May Counties. Larval infestations
are declining in sweet corn as the population ages. Second generation moths begin flying at 1200
degree days (base 50) which has been reached across the state now.
Corn earworm –
Blacklight counts are very low in the northern half of the state. Populations are higher in the southern half of
the state. The highest counts occur in
Salem, Cumberland, Atlantic and Cape May Counties. Silk spraying schedules given below:
North Jersey – 5 day schedule
Central Jersey – 4 to 5 day schedule
South Jersey – 3 to 4 day schedule
Brown marmorated
stinkbug – Very low counts in north Jersey but numbers increase in southern
Jersey. Only one site in the state, in
Salem County, exceeds 5 stinkbugs per night.
No reports of vegetable damage, as yet.
Beet armyworm –
Counts remain low with the highest counts of 5 per night occurring in Atlantic
and Cape May Counties.
Yellow striped
armyworm – We normally don’t track this insect pest but at least one
blacklight trap in Salem County shows large numbers of moths being caught. We may see another large larval population in
the next generation of caterpillars.
