False White Mold. Usually turns yellow after a few days and doesn’t have sclerotia (white\/brown birdshot sized BB’s) and is harmless.<\/figcaption><\/figure>\n\n\n\n

Not white mold. Corky, warty growth on peanut pods are often found when the peanuts are growing in wet soils.  The corky growths are benign and they may be an attempt by the plant to increase gas exchange with the pod in saturated soils.  The pods and plant are not negatively affected. It is not disease or nematodes – Kemerait. (Pic – Ben Reeves, Berrien Co)<\/figcaption><\/figure>\n\n\n\n

Worms in Peanut<\/p>\n\n\n\n

Worms are showing up in some fields. Velvet bean caterpillars and loopers have been found. Threshold is 4-8 worms\/foot. Lower threshold (4) for younger, smaller or stressed plants and higher (8) threshold for older, larger, healthier plants. Diflubenzuron (dimilin) works well on velvet bean caterpillars but not on loopers. <\/p>\n\n\n\n
