Pest description and crop damage Meadow plant bug adults are dirty yellow and dark brown, narrow, about 0.375 inch long, with either short or long wings. They have a rank odor. They suck plant juices and reduce seed yields if abundant. They produce "silver top" by feeding on the stem just above the uppermost node.
Open field burns control this pest by killing any adults and nymphs present during burn. Most important, fire destroys the straw in which the eggs overwinter.
