What about Stink Bugs?
Stink Bug Population Dynamics
Wheat (hypothetical)
Aerial insecticide applications focused on
fungicidal applications over tassling corn
are ineffective
but they are likely too late to do any
good anyway.
Stink bugs in wheat and corn, 3 hours postmarking, prior to wheat harvest
Stink bugs in corn, 2 days post-marking, prior to
wheat harvest
Stink bugs in corn, 4 days post-marking, 2 days
post-wheat harvest
Stink bugs in corn, 6 days post-marking, 4 days
post-wheat harvest
Stink bugs in corn, 8 days post-marking, 6 days
post-wheat harvest
Stink bugs in corn, 10 days post-marking, 8 days
post-wheat harvest
Summing Up Corn Stink Bug Management
• Check adjacent wheat for stink bugs
– Average stink bug density in 120 NC and VA fields
during 2011 was 1.9 in 20 sweeps at peak
infestation
– Watch when 5 or more brown stink bugs in 20
sweeps
– Check status of weeds in adjoining ditches
0.24 stink bugs/m2
2.09 stink bugs/m2
0.02 stink bugs/m2
Summing Up Stink Bug Management
in Corn
• Georgia thresholds
– Prior to VT - 25% infested plants
– R1 - 50% infested plants
– R3 - 100% infested plants
• Spray ~7 days after adjacent wheat harvest
