21 What about Stink Bugs?

22 Stink Bug Population Dynamics Wheat (hypothetical)

23 Aerial insecticide applications focused on fungicidal applications over tassling corn are ineffective but they are likely too late to do any good anyway.

24 Stink bugs in wheat and corn, 3 hours post- marking, prior to wheat harvest

25 Stink bugs in corn, 2 days post-marking, prior to wheat harvest

26 Stink bugs in corn, 4 days post-marking, 2 days post-wheat harvest

27 Stink bugs in corn, 6 days post-marking, 4 days post-wheat harvest

28 Stink bugs in corn, 8 days post-marking, 6 days post-wheat harvest

29 Stink bugs in corn, 10 days post-marking, 8 days post-wheat harvest

31 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

32

33 0.24 stink bugs/m 2 2.09 stink bugs/m 2 0.02 stink bugs/m 2

34 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
