Soybeans
Continue sweeping for stink bugs, especially in double crop beans. As full season beans begin senescing, stink bugs may move and concentrate in later plantings. Once beans reach R6.5, stink bug thresholds increase dramatically. Soybean looper and bean leaf beetle populations are generally present, but in low numbers.
Sorghum
Sugarcane aphids are present in some fields. Fields that have reached the hard dough stages are less likely to incur problems. Fields that have isolated hot spots or sugarcane aphid and with abundant natural enemies seem to have had corn leaf aphids in them earlier this season. Be sure to scout for honeydew or for aphids in sorghum fields that may have been treated with an insecticide earlier this year and late fields that are younger than soft dough.
