Stink Bugs in Field Crops

The row crops in the Mid-Coast of Texas continues to progress at a normal rate. Cotton field maturity ranges from late squaring to the second week of bloom. Grain sorghum fields are from late bloom to near hard dough. And soybeans are blooming (R2), setting pods (R4) and filling pods (R5). In all of these crops, stink bugs are one of the primary insect pests of concern.  After bloom, cotton fields should be checked for stink bug management by opening 1-inch bolls and checking the inside for evidence… Read More →
