Reports of grasshopper damage to soybean have been received during the past week. Dry weather and dry-down of grasses in field borders and waterways will force grasshoppers into growing field crops. Economic thresholds and insecticides labeled for grasshopper in most crops and non-cropland areas can be found in a previous newsletter published earlier in 2011. Grasshopper numbers often occur on a 4-5 year cycle and this looks like a peak year for grasshoppers in most areas of Missouri.
