Please click “”More”” to view the most recent update on BMSB distribution in Virginia soybean (please see slide 1 of the attached pdf document). On August 20, our soybean scout Ed Seymore reported that in the last week stink bugs have started to move out of corn and into soybean fields in the counties of Culpeper, Fauquier, Franklin, King George, Rappahannock, Rockingham, Spotsylvania and Stafford. These counties have reached the threshold for stink bugs of 5 stink bugs in 15 sweeps (in the fields that we scouted). Attention should be paid to fields that border corn and woods especially with the tree of heaven (end report from Mr. Seymore). Note that thresholds in soybean do not distinguish between BMSB and native green and brown stink bug species (also shown on slide 1). Dr. Herbert’’s insecticide efficacy trials and on-farm edge treatment research suggest that most insecticides provide initial stink bug knock down (please refer to slides 2 and 3 for efficacy trial results, where the higher percent control, the better). Residual activity varies, and reinvasion can occur after loss of residual protection. Since BMSB exhibit a strong soybean field edge preference, perimeter-only treatments may be effective. Please remember to always base management decisions on proper scouting and thresholds, and always read and follow the pesticide label (sometimes, products and/or rates that we include in our tests are experimental; also, product labels and rates may change from year to year).
