Thrips rarely require treatment; however, early season injury, in combination with spider mites or leafhoppers, to drought-stressed plants may occasionally reduce yields. Both nymphs and adults feed on the underside of the leaves, causing small silvery streaks and whitish or yellowish discoloration. Treatment may be required when injury appears on drought-stressed plants and more than eight thrips per leaflet are found. Treatment is not recommended in nonstressed fields because soybeans can tolerate thrips injury.
