Japanese beetles are beginning to emerge in Missouri.
Populations are low now but activity is expected to increase over the next two to four weeks. Early scouting helps guide timely management decisions.
What to look for:
• In soybeans, check multiple areas and estimate overall defoliation. Beetles often feed in the upper canopy, leaving a skeletonized look where only leaf veins remain.
• In corn, watch for beetles feeding on silks during pollination. Pay attention if silks are clipped very short, especially when beetle numbers are high and pollination is not complete.
