Congratulations to John Swaine for correctly identifying the cause of the silvery streaking in corn as thrips feeding. Thrips generally are not considered an economic threat to either corn or soybean. In soybean, thrips might become important in hot, dry conditions in which bean plants are not growing and more than 8-12 thrips per leaflet can be found.
